Ge Substrate Txhais
Ge substrate yog hais txog lub substrate ua los ntawm cov khoom germanium (Ge).Germanium yog cov khoom siv semiconductor nrog cov khoom siv hluav taws xob tshwj xeeb uas ua rau nws haum rau ntau yam kev siv hluav taws xob thiab optoelectronic.
Ge substrates feem ntau yog siv los tsim cov khoom siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv kev siv tshuab semiconductor.Lawv yog siv los ua cov ntaub ntawv hauv paus rau tso cov yeeb yaj kiab nyias thiab cov txheej txheem epitaxial ntawm lwm cov khoom siv hluav taws xob xws li silicon (Si).Ge substrates tuaj yeem siv los loj hlob heterostructures thiab cov txheej txheem semiconductor nrog cov khoom tshwj xeeb rau kev siv xws li kev kub ceev transistors, photodetectors, thiab hnub ci hlwb.
Germanium kuj tseem siv rau hauv photonics thiab optoelectronics, qhov twg nws tuaj yeem siv los ua lub substrate rau loj hlob infrared (IR) detectors thiab lo ntsiab muag.Ge substrates muaj cov khoom tsim nyog rau cov ntawv thov infrared, xws li kev sib kis dav dav hauv thaj tsam nruab nrab-infrared thiab cov khoom siv zoo heev ntawm qhov kub thiab txias.
Ge substrates muaj cov qauv sib txuas zoo sib xws rau silicon, ua rau lawv sib haum rau kev sib koom ua ke nrog Si-based electronics.Qhov kev sib raug zoo no tso cai rau kev tsim cov qauv hybrid thiab txhim kho cov khoom siv hluav taws xob thiab photonic siab heev.
Hauv cov ntsiab lus, Ge substrate yog hais txog lub substrate ua los ntawm germanium, cov khoom siv semiconductor siv hauv kev siv hluav taws xob thiab optoelectronic.Nws ua haujlwm raws li lub platform rau kev loj hlob ntawm lwm cov khoom siv semiconductor, ua rau kev tsim khoom ntawm ntau yam khoom siv hauv cov khoom siv hluav taws xob, optoelectronics thiab photonics.
