摘要

循环激励过程(CEP)是一种在低工作偏置下具有高增益、低噪声的信号放大机制1,2。非晶硅作为一种无序材料，具有丰富的局域态，由于俄歇激发涉及局域态，CEP效应可能在非晶硅中表现突出。本文提出了一种具有超高增益带宽产品和极低多余噪声因数的碳掺杂非晶硅光电二极管。

Quantum detectors using cycling excitation process in disordered medium

Cycling excitation process (CEP) is a signal amplification mechanism showing high gain, low noise at low operation bias1,2. Depending on Auger excitation that involves localized states, CEP effect may be prominent in amorphous silicon, which has abundant localized states as a disordered material. Here we present a carbon-doped amorphous Si photodiode with ultra-high gain-bandwidth product with exceedingly low excess noise factor.
