Two-dimensional coordinate-sensitive photodetectors based on (p)InSb–(n)CdTe heterojunction

Photosensitivity of locally irradiated ( n )CdTe–( p )InSb heterojunction formed by the pulsed laser deposition of CdTe thin layer was investigated. Two-coordinate sensitive IR photodetectors based on such heterojunction were fabricated, and it was shown that they have the linear output characterist...

More Information
Summary:Photosensitivity of locally irradiated ( n )CdTe–( p )InSb heterojunction formed by the pulsed laser deposition of CdTe thin layer was investigated. Two-coordinate sensitive IR photodetectors based on such heterojunction were fabricated, and it was shown that they have the linear output characteristics. The measured value of coordinate sensitivity is about 30 nA/μm.
