Khoom Taw Qhia Thiab Daim Ntawv Thov Ntawm Gallium Arsenide

Gallium arsenide, nrog rau cov tshuaj formula GaAs, yog ib pawg III-V compound semiconductor. Nws yog tsim los ntawm arsenic thiab gallium. Nws muaj lub ntsej muag grey ci ntsa iab, nws yog xim hlau ci, thiab nkig thiab tawv. Compound semiconductor cov ntaub ntawv, nrog cov yam ntxwv zoo xws li cov zaus siab, siab electron txav, siab tso zis zog, tsis tshua muaj suab nrov thiab zoo linearity, yog ib qho tseem ceeb tshaj plaws txhawb cov ntaub ntawv rau optoelectronics thiab microelectronics industries.
Ntawm cov ntawv thov hauv kev lag luam optoelectronics, GaAs ib leeg siv lead ua tuaj yeem siv los ua LDs (lasers), LEDs (light-emitting diodes), optoelectronic integrated circuits (OEICs), thiab photovoltaic li.
Ntawm daim ntawv thov hauv kev lag luam microelectronics, nws tuaj yeem siv los ua MESFET (Metal Semiconductor Field Effect Transistor), HEMT (High Electron Mobility Transistor), HBT (Heterojunction Bipolar Transistor), IC, microwave diode, Hall device, thiab lwm yam.
Nws feem ntau suav nrog high-end tub rog siv hluav taws xob siv hluav taws xob, kev sib txuas lus fiber ntau, broadband satellite wireless kev sib txuas lus, cov cuab yeej ntsuas, tsheb hluav taws xob, lasers, teeb pom kev zoo thiab lwm yam haujlwm. Raws li ib qho tseem ceeb ntawm cov khoom siv semiconductor, lub zog hluav taws xob ntawm GaAs yog tsib npaug ntawm silicon thiab gallium nitride. Nws yog siv rau hauv cov khoom siv hluav taws xob me me thiab nruab nrab nrog lub zog qis dua. Yog li ntawd, nws yog siv rau hauv kev sib txuas lus hauv xov tooj, hauv cheeb tsam wireless networks, GPS thiab tsheb radar. tseem ceeb hauv.
