A first-principles technique capable of describing the nearly excited states of semiconductors and insulators,namely the modified Becke-Johnson (mBJ) potential
A new polarimetric optical time domain reflectometry(P-OTDR)measurement device assisted by a high speed polarization analyzer is designed and a new algorithm,wh
Using acoustic microscopy at higher frequency,we show the velocity evolutions of surface acoustic waves,in particular Rayleigh waves that depend on porosity for
Rhombohedral BaTiO3 under hydrostatic pressure is investigated by first principles calculations.Our results show that just like tetragonal perovskites, as press
We study the materials that are composed of metals and insulators.These plasmonic and non-plasmonic materials are ordered in geometric arrangements with dimensi
