NettetBoth discrepancies, in resistivity activation energy and in mobility values, can be explained in terms of the type-II band alignment in the NWs caused by the WZ/ZB polytypism [18–20].A simplified band alignment diagram of a section of a GaAs NW is shown in Figure 1(d). Due to this band alignment, WZ segments act as electron … NettetThe intrinsic carrier concentration is the number of electrons in the conduction band or the number of holes in the valence band in intrinsic material. This number of carriers depends on the band gap of the material and on the temperature of the material. A large band gap will make it more difficult for a carrier to be thermally excited across ...
