Unified semiclassical approach to electronic transport from diffusive to ballistic regimes
《Chinese Physics B》2016年第9期489-494,共6页耿浩 邓伟胤 任月皎 盛利 邢定钰 
Project supported by the National Basic Research Program of China(Grant Nos.2015CB921202 and 2014CB921103);the National Natural Science Foundation of China(Grant No.11225420)
We show that by integrating out the electric field and incorporating proper boundary conditions,a Boltzmann equation can describe electron transport properties,continuously from the diffusive to ballistic regimes.Gene...

The quantum spin Hall （QSH） effect is considered to be unstable to perturbations violating the time-reversal （TR） symmetry. We review some recent developments in the search of the QSH effect in the absence of the ...
