Abstract
The behavior of photocarriers in a GaAs planar n-channel device as an optical detector is studied. Computer simulations show that space charges of those photogenerated carriers give rise to a high-gain and high-speed amplification mechanism which results in Gunn oscillations at intense irradiations. Experiments have confirmed these oscillations. The observed results agree with theoretical computations.
