Nonlinear photoluminescence imaging of isotropic and liquid crystalline dispersions of graphene oxide
Bohdan Senyuk, Natnael Behabtu, Benjamin G. Pacheco +5
We report a visible-range nonlinear photoluminescence (PL) from graphene oxide (GO) flakes excited by near-infrared femtosecond laser light. PL intensity has nonlinear dependence o…
Three-dimensional patterning of solid microstructures through laser reduction of colloidal graphene oxide in liquid-crystalline dispersions
Bohdan Senyuk, Natnael Behabtu, Angel Martinez +6
Graphene materials and structures have become an essential part of modern electronics and photovoltaics. However, despite many production methods, applications of graphene-based st…
Earth-abundant and Non-toxic SiX (X=S, Se) Monolayers as Highly Efficient Thermoelectric Materials
Ji-Hui Yang, Qinghong Yuan, Huixiong Deng +2
Current thermoelectric (TE) materials often have low performance or contain less abundant and/or toxic elements, thus limiting their large-scale applications. Therefore, new TE mat…
Elasticity, Flexibility and Ideal Strength of Borophenes
Zhuhua Zhang, Yang Yang, Evgeni S. Penev +1
We study the mechanical properties of two-dimensional (2D) boron, borophenes, by first-principles calculations. The recently synthesized borophene with 1/6 concentration of hollow…
Assessment of a nonempirical semilocal density functional on solids and surfaces
Yuxiang Mo, Roberto Car, Viktor N. Staroverov +2
Recently, Tao and Mo developed a new nonempirical semilocal exchange-correlation density functional. The exchange part of this functional is derived from a density matrix expansion…
Predicting Band Gaps with Hybrid Density Functionals
Alejandro J. Garza, Gustavo E. Scuseria
We compare the ability of four popular hybrid density functionals (B3LYP, B3PW91, HSE, and PBE0) for predicting band gaps of semiconductors and insulators over a large benchmark se…
