Microwave photo-voltaic oscillations in the GaAs/AlGaAs system
ORAL
Abstract
Microwave photo-excitation of the GaAs/AlGaAs system produces oscillations in the diagonal resistance that lead into novel zero-resistance states in the low temperature limit. Such photo-excitation also produces concomitant photo-voltage oscillations. Here, we examine this microwave photo-voltaic effect and correlate the results with observed magneto-transport over the frequency range $30 \le f \le 120 GHz$ in Hall bars fabricatedfrom material characterized by n = 2x $10^{11} cm^{-2}$.
