Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents infrared nano-spectroscopy and nano-imaging studies of graphene plasmons using scattering-type scanning near-field microscope - a unique technique allowing efficient excitation and high-resolution imaging of graphene plasmons. With this technique, we show in real space that common graphene/SiO2/Si back-gated structure support propagating surface plasmons in the infrared frequencies. The observed plasmons are highly confined surface modes with a wavelength around 200 nm that are conveniently tunable by the back gate voltages. In addition, we perform spectroscopic studies on graphene by varying the probing frequencies. The spectroscopy results not only show direct signature of graphene plasmons but also provide evidence of strong coupling between graphene plasmons and SiO2 optical phonons. Furthermore, we investigate the plasmonic properties of bernal-stacking bilayer graphene (BLG) and find that BLG supports gate-tunable infrared plasmons with higher confinement compared to graphene and randomly stacked graphene layers. Moreover, BLG plasmons can be turned off completely in wide gate voltage close to the charge neutrality point. Those unique plasmonic properties are attributed to both interlayer tunneling and bandgap opening inBLG. Finally, we are able to map and characterize grain boundaries inside graphene film fabricated with chemical vapor deposition (CVD) method by launching surface plasmons. We found grain boundaries, as well as other line defects in CVD graphene, trigger distinct plasmonic twin fringes patterns due to plasmon interference. Theoretical modeling and analysis unveil unique electronic properties associated with grain boundaries.

Download or read book Infrared Nanophotonics written by Tadaaki Nagao and published by MDPI. This book was released on 2021-04-21 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared light radiates from almost all the matter on earth, and its strategic use will be an important issue for the enhancement of human life and the sustainable development of modern industry. Since its frequency is in the same region as phonons or molecular vibrations of materials, measuring its emission or absorption spectra helps us in characterizing and identifying materials in a non-destructive manner. Meanwhile, if we can spectroscopically design infrared emission by tuning chemical composition or artificially controlling nano- to mesoscale structures, this will have a great impact on industrial applications, such as thermophotovoltaics, energy-saving drying furnaces, spectroscopic infrared light sources, and various types of infrared sensors. In this Special Issue, we encourage submissions from researchers who are working on infrared nanophotonics based on MEMS/NEMS, and nanomaterials science, ranging from materials synthesis, to device fabrications, electromagnetic simulations, and thermal managements. Important topics of growing interest are wavelength-selective infrared emitters and detectors, where we can see rapid development in the fields of nano-plasmonics and metamaterials, and we invite such topics for inclusion in this Special Issue. We also encourage submissions on nano-materials science such as on graphene-based infrared detectors/emitters, and nanostructured narrow-band gap semiconductors.

Download or read book Physics and Chemistry of Graphene Second Edition written by Toshiaki Enoki and published by CRC Press. This book was released on 2019-11-01 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphene has been attracting growing attentions in physics, chemistry, and device applications after the discovery of micromechanically cleaved graphene sheet by A. Geim and K. Novoselov, who were awarded the 2010 Nobel Prize in Physics. The electronic structure of graphene, which is described in terms of massless Dirac fermions, brings about unconventional electronic properties, which are not only an important basic issue in condensed matter physics but also a promising target of cutting-edge electronics/spintronics device applications. Meanwhile, from chemistry aspect, graphene is the extreme of condensed polycyclic hydrocarbon molecules extrapolated to infinite size. Here, the concept on aromaticity, which organic chemists utilize, is applicable. Interesting issues appearing between physics and chemistry are pronounced in nanosized graphene (nanographene), as we recognize the importance of the shape of nanographene in understanding its electronic structure. This book comprehensively discusses the fundamental issues related to the electronic, magnetic, and chemical properties of condensed polycyclic hyodrocarbon molecules, nanographene, and graphene.
Download or read book Probing the Response of Two Dimensional Crystals by Optical Spectroscopy written by Yilei Li and published by Springer. This book was released on 2015-11-09 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the study of the optical response of new atomically thin two-dimensional crystals, principally the family of transition metal dichalcogenides like MoS2. One central theme of the thesis is the precise treatment of the linear and second-order nonlinear optical susceptibilities of atomically thin transition metal dichalcogenides. In addition to their significant scientific interest as fundamental material responses, these studies provide essential knowledge and convenient characterization tools for the application of these 2D materials in opto-electronic devices. Another important theme of the thesis is the valley physics of atomically thin transition metal dichalcogenides. It is shown that the degeneracy in the valley degree of freedom can be lifted and a valley polarization can be created using a magnetic field, which breaks time reversal symmetry in these materials. These findings enhance our basic understanding of the valley electronic states and open up new opportunities for valleytronic applications using two-dimensional materials.
