Disorder-induced double resonant Raman process in graphene
J. F. Rodriguez-Nieva, E. B. Barros, R. Saito +1
An analytical study is presented of the double resonant Raman scattering process in graphene, responsible for the D and D features in the Raman spectra. This work yields…
New Method to Detect the Transport Scattering Mechanisms of Graphene Carriers
Shuang Tang, Mildred S. Dresselhaus
Detecting the carrier scattering mechanisms in a materials system is important for transport related science and engineering. The approaches of fast laser process and electrical co…
Ab initio study of electron-phonon interaction in phosphorene
Bolin Liao, Jiawei Zhou, Bo Qiu +2
The monolayer of black phosphorous, or phosphorene, has recently emerged as a new 2D semiconductor with intriguing highly anisotropic transport properties. Existing calculations of…
Group theory for structural analysis and lattice vibrations in phosphorene systems
J. Ribeiro-Soares, R. M. Almeida, L. G. Cançado +2
Group theory analysis for two-dimensional elemental systems related to phosphorene is presented, including (i) graphene, silicene, germanene and stanene, (ii) dependence on the num…
Breit-Wigner-Fano lineshapes in Raman spectra of graphene
Eddwi H. Hasdeo, Ahmad R. T. Nugraha, Mildred S. Dresselhaus +1
Excitation of electron-hole pairs in the vicinity of the Dirac cone by the Coulomb interaction gives rise to an asymmetric Breit-Wigner-Fano lineshape in the phonon Raman spectra i…
Anisotropic Transport for Parabolic, Non-Parabolic and Linear Bands of Different Dimensions
Shuang Tang, Mildred Dresselhaus
Anisotropic thermoelectrics is a very interesting topic among recent research. The transport distribution function plays the central role on modeling the anisotropic thermoelectric…
