Schottky Barrier Modulation for Electronic Shutter Operation of Si Based IR Photodetector

摘要

We proposed and verified electronic shutter of a nano-antenna typed infrared photodetector by using Schottky Barrier Height modulation. Optical detection measurement synchronized with the barrier height modulation could be carried out by our proposed method. This method does not require any mechanical shutter so that system can be compact enough to set at the tip of an endoscopy.
