Figure 3From: Electronic properties of core-shell nanowire resonant tunneling diodesVariation of the lowest sub-band energy. (a) In the middle shell of 20 nm GaAs/10 nm Al0.3Ga0.7As/10 nm GaAs/10 nm Al0.3Ga0.7As/20 nm GaAs core-shell NW. (b) In the core, middle, and surface shells versus thickness of core taken to be equal to the surface shell.Back to article page
