Abstract

We have studied quantum effects on the piezoresistance (PR) of various kinds of low-dimensional heterostructures. The PR is strongly enhanced by electron interference in Q1D electron systems, by Landau qunatization in 2DEG systems, and also by the localizeddelocalized electronic state transition in quantum Hall systems. We have also studied PR for superconductor/semiconductor junctions and found that PR was enhanced at the critical current. In each system, the nonlinear response of device conductance against the change of magnetic field or bias current is responsible for the resistance change against the strain.
