Development of infrared physics and photoelectronic technique at Shanghai Institute of Technical Physics

摘要

Abstract: This paper briefly presents the recent development of IR physics and photo-electronic device, the HgCdTe detector is successfully used in the scanning radiometer on the meteorological satellites. As an important developing direction for the photo-electronic device, the low dimensional semiconductor structures are investigated. The interface intermixing technique has been developed to modify the energy band structure of multi-quantum wells and consequently response wavelength of the quantum well IR photoconductive detector. The quantum wires have been successfully grown and demonstrate good optical properties. !15
