| Abstract: | The interface resistance between the metal and semiconductor components of a hybrid structure can be altered by external perturbations such as a magnetic or strain field. For selected geometries, such perturbations give rise to a redistribution of current flow in the metal and semiconductor that results in a large amplification of the effective resistance of the hybrid. Two examples of this general phenomenon, extraordinary magnetoresistance (EMR) and extraordinary piezoconductance (EPC) are presented. |
