This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Compact models are tools used by the semiconductor industry for digital prototyping of integrated circuits. They are analytical parametrizations of the current-voltage characteristics of nanoelectronic devices in terms of hundreds or thousands of empirical parameters. In this thesis, we present accurate compact models of ballistic metal-oxide-semiconductor field-effect transistors using less than ten parameters, all of which have a clear physical interpretation. In addition to having great predictive power, the models that we present are important conceptual guides for device research and development. We focus our attention on transistors composed of monolayer black phosphorus, a two-dimensional semiconductor with unique electronic and mechanical properties which make it a promising candidate for novel digital logic applications." --

This book was released on 2016 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, a new semiconducting 2D material, black phosphorus, has piqued the interest of research groups in the field. In its bulk form, black phosphorus was synthesized over a century ago and in 2014 devices based on thin flakes of black phosphorus were successfully realized. This was a crucial step towards the exploration and characterization of this material. However, because this material was virtually ignored until this point, many open questions needed to be quickly addressed. Fundamental properties such as the band gap, carrier mobility, optical spectrum, and thermal transport had not been established. Furthermore, the effect of extrinsic factors such as the number of layers, external electric fields, and applied strain had not been explored. How these extrinsic factors affect the tunability of the aforementioned physical properties is of utmost importance for device engineers.Using first principle computations based on density functional theory and the GW approximation including many-electron effects, we calculate the fundamental electronic and optical properties of few-layer black phosphorus. Beyond basic calculations, such as the band structure, quasiparticle band gap, and optical absorption spectrum, we dig deeper to explore the origin and nature of some of black phosphorus' unusual and surprising properties. These properties include the existence of relativistic Dirac fermions as charge carriers, a highly anisotropic band structure, an anisotropic optical absorption spectrum, quasi-1D excitonic features, and an ultra-high sensitivity to a gate electric field.In the first chapter, we discuss the properties of few-layer black phosphorus. We calculate the quasiparticle band gap, and excitonic optical spectra for 1-4 layers. We provide an empirical formula in the form of a power law to fit the calculated results and predict the values for larger layer numbers. We also propose an effective mass hydrogenic model to describe the excitonic spectra calculated. We use a symmetry analysis of the wavefunctions to determine the optical selection rules present in black phosphorus and use the rules to explain the observed anisotropic absorption spectra. Finally, we employ a Wannier function decomposition of the valence bands to illuminate the origin of the anisotropic band dispersion in black phosphorus.In the fourth chapter, we discuss the electronic and optical properties of phosphorene nanoribbons. Using first principles calculations, we find that due to the anisotropic band dispersion present in monolayer phosphorene, nanoribbons cut along the armchair and zigzag directions differ drastically in their properties. We show that the band gap of armchair nanoribbons obeys the usual quantum confinement law of mass particles, while the band gap of zigzag nanoribbons obey a law consistent with Dirac fermions. We show that this is a manifestation of the unique relativistic dispersion in phosphorene.Finally, we discuss the effect of interlayer interactions in few-layer and multilayer black phosphorus. We determine that tunneling through the van der Walls interlayer barrier plays a key role in determining the band gap behavior with respect to the number of layers. We use this to create a model that accurately describes the band gap evolution with the number of layers and the band gap under the application of a gate electric field. Our results show that the strength of the interlayer interaction is in a unique range compared with other layered materials. The interlayer interaction leads to a very large sensitivity of the band gap to a gate electric field. This ultra-high tunability could be very useful for future devices.

This book was released on 2019 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aggressive scaling of Silicon-based MOSFETs in the past decades have contributed immensely to the performance increase of modern electronics. However, at extreme scaling nodes, what was a solution is now the problem when power dissipation in its static and dynamic form have magnified and already reached the cooling limits. The static power dissipation is related to the short channel effect and can be limited by using other material systems that is immune to the short channel effect such as, two-dimensional semiconductors. The dynamic power dissipation can be reduced by allowing the frequency to increase without costing power dissipation. This can be possible if the device is not designed on a thermionic injection which is limited by the subthreshold swing of 60 mV/dec, but rather on a tunneling transport mechanism which in theory can go far beyond the 60 mV/dec. It is, however, the low saturation ON current of the Si-based T-FETs that hinder their progress. In our work, we combine the high mobility two-dimensional semi-conductive black phosphorus material, which has a 1) low effective mass value, 2) favorable band gap value and 3) short electrostatic length and therefore immune to the short channel effect and, with the vital device design of Tunnel-FETs. A combination of scrupulous black phosphorus FET device optimization process, e-beam lithography micro-alignment skill, and shadow deposition technique was used to realize our black phosphorus-based T-FET device. We have achieved high ON current values (1.4 uA/um), high ON/OFF ratio ( 10 ^3), high mobilities (300-400 cm ^2 V^(-1) S^(-1)), and low subthreshold swing (0 mV/dec). We have also marked these T-FET metrics against different temperatures, and also against the crystal orientation of the two-dimensional material. This research proves the applicability of Van der Wal materials in tunnel FET devices in particular and low power electronics in general, and widen the path for greener, high-performance, and energy-efficient devices.

This book was released on 2019 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorene-a two-dimensional layered semiconductor derived from the exfoliation of black phosphorus (BP)-is attracting significant interest in the nanomaterials community due to its high charge-carrier mobility, tunable bandgap, and anisotropic properties, but suffers rapid degradation upon exposure to ambient conditions. Herein we demonstrate the stabilization of phosphorene nanosheets via controlled chemical modification with organic azides, a relatively mild pathway towards covalent functionalization of the phosphorene surface, allowing for greater control over surface functionalization while preventing destructive phosphorene oxidation. Treated phosphorene exhibits a remarkable increase in ambient stability versus untreated phosphorene. This method offers further potential for the controlled, rational design of highly-tunable phosphorene-based materials using fundamental phosphorus chemistry as a guide.

This book was released on 2013-12-01 with total page 1580 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Proceedings of the 17th International Conference on the Physics of Semiconductors are contained in this volume. A record 1050 scientists from 40 countries participated in the Conference which was held in San Francisco August 6·1 0, 1984. The Conference was organized by the ICPS Committee and sponsored by the International Union of Pure and Applied Physics and other professional, government, and industrial organizations listed on the following pages. Papers representing progress in all aspects of semiconductor physics were presented. Far more abstracts (765) than could be presented in a five-day meeting were considered by the International Program Committee. A total of 350 papers, consisting of 5 plenary, 35 invited, and 310 contributed, were presented at the Conference in either oral or poster sessions. All but a few of the papers were submitted and have been included in these Proceedings. An interesting shift in subject matter, in comparison with earlier Conferences, is manifested by the large number of papers on surfaces, interfaces, and quantum wells. To facilitate the use of the Proceedings in finding closely related papers among the sometimes relatively large number of contributions within a main subject area, we chose not to arrange the papers strictly according to the Conference schedule. We have organized the book, as can be seen from the Contents, into specific subcategories and subdivisions within each major category. Plenary and invited papers have been placed together with the appropriate contributed papers.
