gallium-arsenide (gaas) 中文意思是什麼
-
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尤其適宜製作8 12 m長波范圍的大面陣探測器。
