Abstract

We investigate the electrical transport in quasi-1D piezo-semiconductive NWs under purely vertical compressive or tensile strains. For simplicity, we exclusively consider the additional band bending originated by the piezoelectric charges assumed to be distributed, with a constant volumic density, within a maximum distance δpiezofrom the metal-to-NW junction. Our calculations demonstrate that the carrier concentration, the energy conduction band profile and the I-V characteristics significantly depend on δpiezo. We therefore propose that I-V measurements can allow to obtain information on δpiezoin strained piezo-semiconductors. © 2013 Materials Research Society.
