Raws li peb txhua tus paub, lub ntsiab lus ntawm semiconductor yog hais tias nws muaj ib tug conductivity ntawm qhuav conductors thiab insulators, resistivity ntawm hlau thiab insulator, uas feem ntau yog nyob rau hauv chav tsev kub yog nyob rau hauv lub cheeb tsam ntawm 1mΩ-cm ~ 1GΩ-cm.Nyob rau hauv xyoo tas los no, Lub tshuab nqus tsev semiconductor txheej hauv cov tuam txhab loj semiconductor, nws yog qhov tseeb tias nws cov xwm txheej tau nce siab, tshwj xeeb tshaj yog nyob rau hauv qee qhov kev sib xyaw ua ke loj hauv kev tsim hluav taws xob hauv kev tshawb fawb thev naus laus zis rau cov khoom siv hluav taws xob hloov pauv magnetoelectric, cov khoom siv hluav taws xob thiab lwm yam kev txhim kho.Vacuum semiconductor txheej muaj lub luag haujlwm tseem ceeb.
Semiconductors yog tus cwj pwm los ntawm lawv cov yam ntxwv ntawm lub cev, kub thiab impurity concentration.Lub tshuab nqus tsev semiconductor txheej cov ntaub ntawv yog qhov txawv ntawm ib leeg los ntawm nws cov khoom sib xyaw.Kwv yees tag nrho yog raws li boron, carbon, silicon, germanium, arsenic, antimony, tellurium, iodine, thiab lwm yam, thiab qee qhov tsawg tsawg GaP, GaAs, lnSb, thiab lwm yam. Muaj qee cov oxide semiconductors, xws li FeO, Fe₂O₃, MnO, Cr₂O₃, Cu₂O, thiab lwm yam.
Nqus evaporation, sputtering txheej, ion txheej thiab lwm yam khoom siv tuaj yeem ua lub tshuab nqus tsev semiconductor txheej.Cov khoom siv txheej txheej no yog txhua yam sib txawv hauv lawv txoj haujlwm ua haujlwm, tab sis lawv txhua tus ua cov khoom siv semiconductor txheej cov khoom tso rau ntawm lub substrate, thiab raws li cov khoom ntawm substrate, tsis muaj qhov yuav tsum tau ua, nws tuaj yeem yog semiconductor lossis tsis.Tsis tas li ntawd, txheej txheej nrog cov khoom siv hluav taws xob sib txawv thiab kho qhov muag tuaj yeem npaj tau los ntawm ob qho tib si impurity diffusion thiab ion implantation rau ntawm qhov chaw ntawm semiconductor substrate nyob rau hauv ntau yam.Cov txheej nyias nyias tuaj yeem ua tiav raws li cov txheej txheem semiconductor feem ntau.
Lub tshuab nqus tsev semiconductor txheej yog qhov tseem ceeb muaj nyob hauv cov khoom siv hluav taws xob txawm tias nws yog rau cov khoom siv ua haujlwm lossis cov khoom siv tsis zoo.Nrog rau kev nce qib txuas ntxiv ntawm lub tshuab nqus tsev semiconductor txheej tshuab, kev tswj xyuas meej ntawm kev ua yeeb yaj kiab tau ua tiav.
Nyob rau hauv xyoo tas los no, amorphous txheej thiab polycrystalline txheej tau ua tiav sai hauv kev tsim cov khoom siv photoconductive, coated field-effect tubes, thiab high-efficiency solar cells.Tsis tas li ntawd, vim yog txoj kev loj hlob ntawm lub tshuab nqus tsev semiconductor txheej thiab nyias zaj duab xis ntawm cov sensors, uas tseem txo qis qhov nyuaj ntawm kev xaiv cov khoom thiab ua rau cov txheej txheem tsim maj mam yooj yim.Lub tshuab nqus tsev semiconductor txheej khoom tau dhau los ua qhov tsim nyog muaj nyob rau hauv daim ntawv thov semiconductor.Cov cuab yeej siv dav siv rau cov khoom siv semiconductor txheej ntawm lub koob yees duab, lub hnub ci hlwb, coated transistors, teb emission, cathode-light, electron emission, nyias zaj duab xis sensing ntsiab, thiab lwm yam.
Lub magnetron sputtering txheej kab yog tsim los nrog lub siab tsis siv neeg tswj qhov system, ib qho yooj yim thiab intuitive kov npo tib neeg-tshuab interface.Cov kab yog tsim los nrog ua tiav cov ntawv qhia ua haujlwm kom ua tiav kev saib xyuas kev ua haujlwm rau tag nrho cov kab ntau lawm, txheej txheem kev teeb tsa, kev tiv thaiv kev ua haujlwm thiab lub tswb.Tag nrho cov kev tswj hluav taws xob muaj kev nyab xeeb, txhim khu kev qha thiab ruaj khov.Nruab nrog rau sab sauv thiab qis dua ob sab magnetron sputtering lub hom phiaj lossis txheej txheej txheej txheej.
Cov cuab yeej siv feem ntau yog siv rau cov khoom siv hluav taws xob ceramic, chip high-voltage capacitors thiab lwm yam txheej txheej substrate, cov ntawv thov tseem ceeb yog cov khoom siv hluav taws xob hluav taws xob.
