关键词:
摘要: An investigation into the effects of thermal interdiffusion on characteristics quantum dot infrared photodetectors (QDIPs) yields results useful for creation a two-colour QDIP. For high temperature rapid annealing, is induced, resulting in large wavelength redshift photodetector spectral response, at cost small degradation device performance. The evaluation QDIP fabricated using selective suppression during annealing shows uniform performance two different detector pixels. This has implications as process future fabrication multi-colour QDIPs.
