Available in PDF, EPUB and Kindle. Book excerpt: A Monte Carlo simulator for silicon devices has been developed. The band structure data for this self-consistent device simulator were computed using the empirical pseudopotential method. The ensemble Monte Carlo technique used in the simulations is described in detail. A homogeneous simulator, based on the same transport physics, is used to calibrate the device simulator as well as to indicate the shortcomings of more traditional simulators such as drift-diffusion based models, hydrodynamic and energy balance based models, and nonparabolic band approximation Monte Carlo models. A conventional metal-oxide-semiconductor field effect transistor (MOSFET) is simulated as a test case to validate the simulator. Finally, a floating gate memory element (non-volatile memory) is also examined. In this simulation, the Monte Carlo simulator is used as a post-processor to PISCES IIB in the interest of execution time. Despite the lack of self-consistency and rigor, the simulator is able to produce results which are in good agreement with experimental data.

Book excerpt: Monte Carlo simulation is now a well established method for studying semiconductor devices and is particularly well suited to highlighting physical mechanisms and exploring material properties. Not surprisingly, the more completely the material properties are built into the simulation, up to and including the use of a full band structure, the more powerful is the method. Indeed, it is now becoming increasingly clear that phenomena such as reliabil ity related hot-electron effects in MOSFETs cannot be understood satisfac torily without using full band Monte Carlo. The IBM simulator DAMOCLES, therefore, represents a landmark of great significance. DAMOCLES sums up the total of Monte Carlo device modeling experience of the past, and reaches with its capabilities and opportunities into the distant future. This book, therefore, begins with a description of the IBM simulator. The second chapter gives an advanced introduction to the physical basis for Monte Carlo simulations and an outlook on why complex effects such as collisional broadening and intracollisional field effects can be important and how they can be included in the simulations. References to more basic intro the book. The third chapter ductory material can be found throughout describes a typical relationship of Monte Carlo simulations to experimental data and indicates a major difficulty, the vast number of deformation poten tials required to simulate transport throughout the entire Brillouin zone. The fourth chapter addresses possible further extensions of the Monte Carlo approach and subtleties of the electron-electron interaction.

This book was released on 2013-04-17 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle simulation of semiconductor devices is a rather new field which has started to catch the interest of the world's scientific community. It represents a time-continuous solution of Boltzmann's transport equation, or its quantum mechanical equivalent, and the field equation, without encountering the usual numerical problems associated with the direct solution. The technique is based on first physical principles by following in detail the transport histories of indi vidual particles and gives a profound insight into the physics of semiconductor devices. The method can be applied to devices of any geometrical complexity and material composition. It yields an accurate description of the device, which is not limited by the assumptions made behind the alternative drift diffusion and hydrodynamic models, which represent approximate solutions to the transport equation. While the development of the particle modelling technique has been hampered in the past by the cost of computer time, today this should not be held against using a method which gives a profound physical insight into individual devices and can be used to predict the properties of devices not yet manufactured. Employed in this way it can save the developer much time and large sums of money, both important considerations for the laboratory which wants to keep abreast of the field of device research. Applying it to al ready existing electronic components may lead to novel ideas for their improvement. The Monte Carlo particle simulation technique is applicable to microelectronic components of any arbitrary shape and complexity.

Download or read book Full band Monte Carlo Simulation of Hot Electrons in Scaled Silicon Devices written by Amanda Watson Duncan and published by . This book was released on 1996 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: A full-band Monte Carlo device simulator has been used to study the effects of device scaling on hot electrons in different types of n-channel MOSFETs and flash memory structures. A MOSFET with a single source/drain implant, an LDD MOSFET, an SOI MOSFET, and a MOSFET built on top of a heavily doped "ground plane" have been simulated. Different scaling techniques have been applied to the devices to see the effects on the electric field, the energy distributions of the electrons, and the drain, substrate, and gate currents. The locations of impact ionization events and injection into the gate oxide are examined. It is shown that simpler models cannot adequately predict hot carrier behavior at the channel lengths studied (below 0.3 $mu$m) and that several strategies that are successful at suppressing the hot carrier population for longer channel lengths are not as useful when 0.1 $mu$m channel lengths are approached. The effect of scaling on the programming of stacked-gate and split-gate flash memory devices was also studied. Predictions of hot carrier behavior in small MOSFETs and flash memory devices are made, and suggestions for device design are given.

Book excerpt: Heat in most semiconductor materials, including the traditional group IV elements (Si, Ge, diamond), III–V compounds (GaAs, wide-bandgap GaN), and carbon allotropes (graphene, CNTs), as well as emerging new materials like transition metal dichalcogenides (TMDCs), is stored and transported by lattice vibrations (phonons). Phonon generation through interactions with electrons (in nanoelectronics, power, and nonequilibrium devices) and light (optoelectronics) is the central mechanism of heat dissipation in nanoelectronics. This book focuses on the area of thermal effects in nanostructures, including the generation, transport, and conversion of heat at the nanoscale level. Phonon transport, including thermal conductivity in nanostructured materials, as well as numerical simulation methods, such as phonon Monte Carlo, Green’s functions, and first principles methods, feature prominently in the book, which comprises four main themes: (i) phonon generation/heat dissipation, (i) nanoscale phonon transport, (iii) applications/devices (including thermoelectrics), and (iv) emerging materials (graphene/2D). The book also covers recent advances in nanophononics—the study of phonons at the nanoscale. Applications of nanophononics focus on thermoelectric (TE) and tandem TE/photovoltaic energy conversion. The applications are augmented by a chapter on heat dissipation and self-heating in nanoelectronic devices. The book concludes with a chapter on thermal transport in nanoscale graphene ribbons, covering recent advances in phonon transport in 2D materials. The book will be an excellent reference for researchers and graduate students of nanoelectronics, device engineering, nanoscale heat transfer, and thermoelectric energy conversion. The book could also be a basis for a graduate special topics course in the field of nanoscale heat and energy.
