Gaas / algaas quantum well photodetectors ( qwips ) are new type devices and progressed rapidly in recent 20 years . qwips utilizing intersubband absorption between gallium arsenide ( gaas ) well and aluminum gallium arsenide ( alxga1 _ xas ) barriers were perfected . therefore , the ability to accurately control the band structure and hence the spectral response , as well as both established technology for growing and processing gaas optical devices and commercially available large area vlsi gaas ic ' s , makes gaas / algaas qwips attractive devices for use in very large focal plane arrays ( fpas ) , especially available in the range of long wavelength 8 - 12 urn Gaas algaas量子阱紅外探測器( qwips )是近二十年來迅速發展起來的一種新型紅外探測器,它成功地利用了gaas勢阱和al _ xga _ ( 1 - x ) as勢壘之間的子帶間吸收,使之具有能帶結構可精確設計從而獲得指定光譜響應的特點,加之成熟的材料生長技術、器件工藝,以及商業上可獲得大面積的vlsigaas集成電路,使得gaas algaasqwips尤其適宜制作8 12 m長波范圍的大面陣探測器。
