Ingaruka za silicon karbide ya diode ikomeye kuri PIN Photodetector

Amashanyarazi menshi ya silicon karbide PIN diode yamye nimwe mubintu bishyushye mubushakashatsi bwibikoresho byamashanyarazi. PIN diode ni kirisiti ya kirisiti yubatswe na sandwiching igice cya semiconductor (cyangwa semiconductor ifite imyanda mike) hagati yakarere ka P + nakarere ka n +. I. -ubwoko cyangwa N ubwoko bwanduye. Kugeza ubu, silicon karbide PIN diode ikoresha ahanini Mesa imiterere nindege.

Iyo inshuro ikora ya diode ya PIN irenze 100MHz, kubera ingaruka zo kubika abatwara bake hamwe nigihe cyo gutambuka mugice cya I, diode itakaza ingaruka zo gukosora ihinduka ikintu cya impedance, kandi agaciro kayo ko guhinduka hamwe na voltage ya bias. Kuri zeru kubogama cyangwa DC ihindagurika kubogama, impedance mukarere ka I ni ndende cyane. Muri DC imbere kubogama, akarere ka I karerekana imiterere mike yo guterwa kubera gutera inshinge. Kubwibyo, diode ya PIN irashobora gukoreshwa nkibintu bihindagurika, mubijyanye na microwave na RF igenzura, akenshi birakenewe gukoresha ibikoresho byo guhinduranya kugirango ugere ku guhinduranya ibimenyetso, cyane cyane mubigo bimwe na bimwe bigenzura ibimenyetso byihuta, diode ya PIN ifite hejuru Ubushobozi bwo kugenzura ibimenyetso bya RF, ariko kandi bikoreshwa cyane muguhindura icyiciro, guhindura, kugabanya no kuzunguruka.

Diode ifite imbaraga nyinshi cyane ya silicon karbide ikoreshwa cyane mumashanyarazi kubera imiterere yayo irwanya imbaraga za voltage, cyane cyane ikoreshwa nkumuyoboro mwinshi wo gukosora. PIN diode ifite reverisiyo ihanitse yo gusenyuka ya voltage VB, kubera doping yo hasi i layer hagati itwara voltage nyamukuru. Kongera umubyimba wa zone I no kugabanya ubukana bwa doping ya zone nshobora kunoza neza imbaraga za reversion breakdown ya voltage ya PIN diode, ariko kuba hari zone nzanoza imbere ya voltage igabanuka VF yibikoresho byose hamwe nigihe cyo guhinduranya igikoresho. kurwego runaka, na diode ikozwe mubikoresho bya silicon karbide irashobora kuzuza izo nenge. Carbide ya silikoni inshuro 10 umurima wamashanyarazi wa silicon ikomeye, kugirango silicon karbide diode I zone yuburebure bwa zone ishobora kugabanuka kugeza kuri kimwe cya cumi cyumuyoboro wa silikoni, mugihe ikomeza imbaraga zumuriro mwinshi, hamwe nubushuhe bwiza bwumuriro wibikoresho bya karubide. , ntakibazo kizaba kigaragara cyo gukwirakwiza ubushyuhe, bityo imbaraga za silicon karbide diode yahindutse igikoresho cyingenzi cyo gukosora mubijyanye na electronics zigezweho.

Kubera ibintu bito cyane bigenda byoroha kandi bigatwara ibintu byinshi, diode ya silicon karbide ikurura cyane murwego rwo kumenya amafoto. Umuyoboro muto ushobora kumeneka urashobora kugabanya umuyaga wijimye wa detector no kugabanya urusaku; Kugenda kwinshi kwabatwara birashobora kunoza neza ibyiyumvo bya silicon karbide PIN detector (PIN Photodetector). Imbaraga-ndende ziranga silicon karbide diode ituma disiketi ya PIN itahura urumuri rukomeye kandi rukoreshwa cyane mumwanya. Diode ikomeye cyane ya silicon karbide diode yitaye kuberako iranga ibyiza, kandi ubushakashatsi bwayo nabwo bwateye imbere cyane.
