Ndezvipi zvinoshandiswasilicon germanium?Mubvunzo uyu unomuka apo isu tinonyura munyika inoshamisa yesilicon germanium (SiGe) upfu.Nekuzama zvakadzama muchinhu ichi chinogoneka, tinoratidza mashandisirwo ayo akasiyana uye basa rayo mumaindasitiri akasiyana.
Silicon germanium poda, inowanzonziSi-Ge hupfu,chinhu chinoumbwa chinosanganisa yakasarudzika silicon uye germanium.Zvinhu izvi zvinosangana kuti zvigadzire chinhu chine yakanakisa magetsi uye chinopisa conductivity, zvichiita kuti chitsvakwe zvakanyanya kune kwakawanda kufambira mberi kwetekinoroji.
Chishandiso chakatanhamara chesilicon germanium upfuiri mumunda we semiconductor.Inoshandiswa zvakanyanya kuvandudza kushanda uye kushanda kwemagetsi emagetsi.Nekubatanidza SiGe poda mune semiconductor zvishandiso, mainjiniya anogona kukurumidza kugadzirisa kumhanya, yakakwirira ma frequency uye yakakwirira simba rekuita.Izvi zvinoitaSiGechinhu chakakosha mukugadzirwa kwema transistors, akasanganiswa maseketi uye zvimwe semiconductor zvishandiso.
Pamusoro pe,silicon germanium upfuinoita basa rakakosha mukuvandudza optoelectronics.Yayo yakasarudzika magetsi emagetsi anogona kushandiswa kugadzira mafotodetectors, laser diode, uye zvimwe optoelectronic zvishandiso.Semuyenzaniso,SiGe-based photodetectors vane high responsivity uye yakaderera rima ikozvino, zvichiita kuti zvive zvakanaka kune zvikumbiro zvakadai se optical communications uye sensing teknolojia.
Pamusoro pemagetsi uye optoelectronics,silicon germanium upfuzvakare ine mashandisiro ayo mumunda we thermoelectric zvinhu.Iyo yakanakisa yekupisa conductivity inosanganiswa neayo magetsi emagetsi zvinobudirira kushandura kupisa kuve simba remagetsi.Izvi zvinoitaSiGe hupfuchinhu chakakosha chekushandisa thermoelectric jenareta, kutambisa kupisa kudzoreredza masisitimu uye humwe hunyanzvi hwekukohwa simba.Kugona kushandisa kupisa kupisa sechinhu chakakosha simba sosi haingobatsiri kusimba asi zvakare inoderedza kushandiswa kwesimba.
Indasitiri yezvemuchadenga inozivawo kugona kwesilicon germanium upfu.Huremu hwayo uye kugadzikana kwepamusoro-tembiricha inoita kuti ive sarudzo yakakodzera yeaerospace application.Silicon-germanium-yakavakirwa macomposites anogona kumirisana nemamiriro akanyanya, achiita kuti ave akakosha kune zvinhu zvemuchadenga senge zvivharo zvekupisa, maroketi nozzles uye zvimiro zvechimiro.Kubatanidzasilicon germanium upfumumashandisirwo akadai anowedzera kuita kwavo kwese uye kuderedza kukanganisa kwezvakatipoteredza.
Mundima yezvokurapa,silicon germanium upfuyakaratidza kuve shanduko yemutambo muchikamu chebiotechnology.Inopa huwandu hwemashandisirwo kubva kune zvinodhaka zvekuendesa zvinodhaka kune biosensing zvishandiso.Nekuda kweiyo biocompatibility,SiGe hupfuinogona kushandiswa kuvhara uye kuendesa zvinodhaka nenzira inodzorwa, kushandura kurapwa kwezvirwere zvakasiyana.Pamusoro pe,SiGe-based biosensors inogona kunyatso uye nekukurumidza kuona biological analytes, kuvhura musuwo wepamusoro diagnostics uye mushonga wakasarudzika.
Sezvo kudiwa kwezvinhu zvitsva uye zvinogara zvichiramba zvichikura,silicon germanium upfundiye mutungamiri mumaindasitiri mazhinji.Hurukuro hwayo hwakasiyana-siyana uye hwakasiyana hunhu hunoita kuti ive chikamu chakakosha chezvakasiyana siyana zvekushandisa, kubva kumagetsi uye optoelectronics kusvika kune simba kukohwa uye aerospace.Kuenderera mberi kwekuvandudzwa uye kuongororwa kweSiGe hupfuine mukana wakakura webudiriro yeramangwana iyo inoumba nyika yedu nenzira dzinoshamisa.
Mushanduko yetekinoroji,silicon germanium upfuiri pamberi, ichigadzirira nzira yezviwanwa izvo pasina mubvunzo zvinotungamirira kune remangwana rakajeka.
