Hot Electron Dynamics in Zincblende and Wurtzite GaN
Clóves Gonçalves Rodrigues, Valder N. Freire, Áurea R. Vasconcellos +1
A theoretical investigation of the excess energy dissipation of highly excited photoinjected electrons in both wurtzite and zincblende GaN is presented. The calculations are perfor…
Mobility in N-Doped Wurtzite III-Nitrides
Clóves Gonçalves Rodrigues, Valder N. Freire, Áurea R. Vasconcellos +1
A study of the mobility of n-doped wurtzite III-Nitrides is reported. We have determined the nonequilibrium thermodynamic state of the III-Nitrides systems, driven far away from eq…
Defects in Graphene-Based Twisted Nanoribbons: Structural, Electronic and Optical Properties
Ewerton W. S. Caetano, Valder N. Freire, Sergio G. dos Santos +3
We present some computational simulations of graphene-based nanoribbons with a number of half-twists varying from 0 to 4 and two types of defects obtained by removing a single carb…
Möbius and twisted graphene nanoribbons: stability, geometry and electronic properties
Ewerton W. S. Caetano, Valder N. Freire, Sergio G. dos Santos +2
Results of classical force field geometry optimizations for twisted graphene nanoribbons with a number of twists varying from 0 to 7 (the case =1 corresponds to a half-t…
