Abstract

We report here the observation of inverse extraordinary optoconductance (I-EOC) in a Ti-GaAs metal-semiconductor hybrid (MSH) structure where the photoconductance of the device decreases as the light intensity increases. The artificially designed MSH structure of Ti forming a Schottky interface with GaAs shows efficient photon sensing not exhibited by bare semiconductors and shows promising potential for several nanophotonic applications.
