Graphene is identified as a zero gap semiconductor and has a novel electronic structure with its conduction band and valence band touching each other at a neutral point.
According to the basic idea of energy band theory,the energy band dispersion E(k)of condensed matters is closely related to their electrical transport properties.Therefore,the electrical transport mea
Using comprehensive first-principles calculations,we report two new kinds of 2D Titanium Carbide(TiC2)monolayer sheet with distinguished structure and properties.
Topological insulators have a bulk band gap as normal insulators but they have protected conducting edge states [for two-dimensions(2D)]and surface states(for 3D).
Bi is a fascinating material that has served many times in history to explore new physical phenomena in condensed matter physics for its extremely small Fermi surface,long Fermi wavelength of itineran
