摘要：
We report calculations of the transit-time limited frequency response of InGaAs interdigitated metal-semiconductor-metal (MSM) Schottky barrier photodetectors for 1.55-?m wavelength incident radiation. We show how the interdigital spacing and thickness of the InGaAs layer influence the impulse response and the associated bandwidth. The tradeoff between speed and quantum efficiency is also examined. © 1990 IEEE
