Ingaruka za silicon karbide ya diode ikomeye kuri PIN Photodetector

Ingaruka za silicon karbide diode ikomeyePIN 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. 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 birakenerwa gukoresha ibikoresho byo guhinduranya kugirango ugere ku guhinduranya ibimenyetso, cyane cyane mubigo bimwe na bimwe bigenzura ibimenyetso byihuta cyane, PIN diode ifite ubushobozi bwo kugenzura ibimenyetso bya RF, ariko kandi bikoreshwa cyane muburyo bwo guhinduranya ibyiciro, guhindura, kugabanya no kuzenguruka.

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. UwitekaPIN diodeifite reverisiyo ihanitse yo gusenya voltage VB, bitewe na doping nkeya i layer hagati itwara voltage nyamukuru. Kongera umubyimba wa zone I no kugabanya ubukana bwa doping ya zone nshobora kunonosora neza imbaraga zogusubira inyuma kumashanyarazi ya diode ya PIN, ariko kuba hari zone nzazamura imbere ya voltage yamanuka ya VF yibikoresho byose hamwe nigihe cyo guhinduranya igikoresho kurwego runaka, kandi diode ikozwe mubikoresho bya karubide ya silicon irashobora kuzuza izo nenge. Carbide ya silicon inshuro 10 umurima wamashanyarazi wa silikoni ikomeye, kugirango silicon karbide diode ya zone yuburebure bwa zone ishobora kugabanuka kugeza kuri kimwe cya cumi cyumuyoboro wa silicon, mugihe ukomeje imbaraga zumuriro mwinshi, hamwe nubushobozi bwiza bwumuriro wibikoresho bya karibide ya silicon, ntihazabaho ibibazo bigaragara byo gukwirakwiza ubushyuhe mumashanyarazi ya elegitoroniki ya kijyambere.

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 karubide ya siliconIkimenyetso cya PIN(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.
