Ingaruka za diode ya silicon carbide ifite imbaraga nyinshi kuri PIN Photodetector

Ingaruka za diode ya silicon carbide ifite imbaraga nyinshi kuPIN ipima foto

Diode ya PIN ya silikoni ifite imbaraga nyinshi yahoraga ari imwe mu ngaruka zikomeye mu bushakashatsi ku bikoresho by'amashanyarazi. Diode ya PIN ni diode ya kristu yubatswe no gushyira urwego rwa semiconductor y'imbere (cyangwa semiconductor ifite umwanda muto) hagati y'akarere ka P+ n'akarere ka n+. Inyuguti ya i muri PIN ni incamake y'icyongereza y'igisobanuro cya "intrinsic", kuko bidashoboka kubaho semiconductor y'umwimerere idafite umwanda, bityo urwego rwa I rwa diode ya PIN mu ikoreshwa ruvanze n'umwanda muto wa P-type cyangwa N-type. Kuri ubu, diode ya PIN ya silikoni ikoresha cyane cyane imiterere ya Mesa n'imiterere y'umurambararo.

Iyo frequency y'imikorere ya diode ya PIN irenze 100MHz, bitewe n'ingaruka zo kubika za carrier nke n'ingaruka z'igihe cyo kunyura mu cyiciro cya mbere, diode itakaza ingaruka zo gukosora ikaba ikintu cya impedance, kandi agaciro kayo ka impedance gahinduka bitewe na voltage ya bias. Kuri zero bias cyangwa DC reverse bias, impedance mu gace ka I iba iri hejuru cyane. Muri DC forward bias, akarere ka I gatanga impedance nke bitewe no guterwa na carrier injection. Kubwibyo, PIN diode ishobora gukoreshwa nk'ikintu cya impedance kidahinduka, mu rwego rwo kugenzura mikoroonde na RF, akenshi biba ngombwa gukoresha ibikoresho byo guhindura kugira ngo hagerwe ku guhindura ibimenyetso, cyane cyane muri bimwe mu bigo bigenzura ibimenyetso bifite frequency nyinshi, PIN diode zifite ubushobozi bwo kugenzura ibimenyetso bya RF, ariko kandi zikoreshwa cyane mu guhindura phase, modulation, limitating n'izindi circuits.

Diode ya silikoni ifite imbaraga nyinshi ikoreshwa cyane mu ngufu kubera imiterere yayo yo kurwanya amashanyarazi menshi, ahanini ikoreshwa nk'umuyoboro wo gusubiza ibintu mu buryo ufite ingufu nyinshi.diode ya PINifite voltage ikomeye ya VB, bitewe n'urwego ruto rwa doping i hagati rutwara igabanuka ry'amashanyarazi. Kongera ubugari bwa zone ya I no kugabanya ingano ya doping ya zone nshobora kunoza neza voltage ya reverse breakdown ya PIN diode, ariko kuba hariho zone ya I bizanoza igabanuka rya voltage ya VF y'igikoresho cyose n'igihe cyo guhinduranya igikoresho ku rugero runaka, kandi diode ikozwe mu bikoresho bya silicon carbide ishobora kwishyura izi ntege nke. Carbide ya Silicon inshuro 10 z'amashanyarazi ya silicon, kugira ngo ubunini bwa silicon carbide diode I zone bushobore kugabanuka kugeza kuri kimwe cya cumi cy'umuyoboro wa silicon, mugihe igumana voltage nyinshi ya breakdown, hamwe n'uburyo bwiza bwo gutwara ubushyuhe bw'ibikoresho bya silicon carbide, nta bibazo bigaragara byo gukwirakwiza ubushyuhe, bityo diode ya silicon carbide ifite ingufu nyinshi yabaye igikoresho cy'ingenzi cyane cyo gutunganya ibintu mu rwego rw'ibikoresho by'ikoranabuhanga bigezweho.

Kubera ko ifite umuyoboro muto cyane wo gusohora amazi inyuma ndetse n'uburyo bwo kugenda cyane, diode za silikoni zifite akamaro kanini mu bijyanye no kubona amashanyarazi. Umuyoboro muto wo gusohora amazi ushobora kugabanya umuyoboro wijimye w'icyuma gipima amazi no kugabanya urusaku; uburyo bwo kugenda cyane bushobora kongera ubushobozi bwo kumva imiterere ya silikoni.Gupima PIN(PIN Photodetector). Imiterere y'imbaraga nyinshi ya diode za silicon carbide ituma PIN detectors ibasha kubona amasoko y'urumuri akomeye kandi ikoreshwa cyane mu kirere. Diode ya silicon carbide ifite imbaraga nyinshi yitabwaho kubera imiterere yayo myiza, kandi ubushakashatsi bwayo bwatejwe imbere cyane.
