The research of InSb on Si avalanche photodiode

We demonstrate a bonding InSb/Si wafer and its application in APD. An InSb/Si APD with high gain and high bandwidth is discussed. Bonding wafer of InSb and Si is suitable to fabricate InSb/Si APD. The InSb/Si APD will have better performance than InSb APD, and it is suited for the detection in passive imaging and active imaging operation.
