Abstract
Capacitance-Voltage characteristics of a metal-semiconductor-metal structure with an embedded two-dimensional electron system are reported. The device functions based on a quantum capacitance, which is activated by local illumination. The giant sensitivity to light and voltage makes this device a candidate for capacitive-based photodetection. © OSA 2013.File in questo prodotto:
