Novel Virtual Substrates for Future Generation IR Photodetectors
Abstract
This research has investigated epitaxial InSb, CdTe, MgCdTe, and CdTe/MgCdTe double heterostructures grown on InSb (100) substrates using molecular beam epitaxy. State-of-the-art materials quality has been successfully achieved in all of these materials, which have demonstrated record narrow X-ray diffraction line-widths, ultra-low defect density, and record long minority carrier lifetime of over 340 ns. All of these findings provide strong evidence that CdTe grown on InSb is highly suitable for use as a virtual substrate for multiple applications, including infrared detectors and the investigation of CdTe solar cells.
