Isantya esiphezulu seefoto ziyaziswaI-Ingaas yeefoto
Iifoto eziphakamileyoKwintsimi yonxibelelwano lwekhephu ikakhulu kubandakanya i-III-v i-photoeteeteeters kunye ne-iv epheleleyo i-ge /Iifoto ze-Silfoeteete. Okwangaphambili ingumnxibelelanisi we-infrared osondeleyo, oye walawula ixesha elide, ngelixa le ndlela ixhomekeke kwitekhnoloji ye-silicon ukuba ibe yinkwenkwezi evuthiweyo, kwaye yindawo eshushu kwicandelo le-Optoelelelelelectronis. Ukongeza, izixhobo ezintsha ezisekwe kwiPerovskite, izixhobo ze-organic kunye neendlela ezimbini zikhula ngokukhawuleza ngenxa yeengenelo zokusebenza ngokulula, ukuguquguquka okuhle kunye nezinto eziguquguqukayo. Kukho umahluko okhoyo phakathi kwaba basebenzi batsha kunye neefoto zemveli zemveli kwizinto ezibonakalayo kunye neenkqubo zemveliso. I-Perovskkite ABHICING ineempawu ezibalaseleyo zokukhanya kunye nezixhobo ezifanelekileyo zokuhlawula ezisetyenziselwa iindleko zazo eziphantsi kunye nezixhobo eziguquguqukayo zitsalele ingqalelo enkulu ngenxa yezinto zabo ezikhethekileyo zomzimba kunye neyonakalisa inkathalo. Nangona kunjalo, xa kuthelekiswa ne-I-I-I-I-I-I-I-I-I-I-I-I-I-A kunye ne-GE / GE / GEACS, AMABINI ENTSHA AKUFUNEKA UQHELEKILE UKUPHILA NGOKUGQIBELA IXESHA LOKUXELISA, UKUQHUTYWA KOMNYANGO NOKUTHENGA.
I-Ingaas yenye yezona zinto zilungileyo zokufumana isantya esiphezulu kunye nempendulo ephezulu yokuphendula. Okokuqala, i-Ingaas yi-bandggap ye-semicondcuctor, kwaye i-bandgap yayo inokulawulwa ngumlinganiselo phakathi kwe-ne kunye ne-ga ukuya kufumanisa ukuba kutshintshwe imiqondiso eyahlukeneyo yamaza amagqabi ahlukeneyo. Phakathi kwabo, i-In0.53ga0.47as ihambelana ngokugqibeleleyo ne-Inp ye-InP, kwaye inolwazi oluninzi olusebenzayo kwibhendi yonxibelelwano, esetyenziswa kakhulu kulungiselelo lweIifoto, kwaye umsebenzi onobumnyama kunye nokuphendula nawo okuphendula kakhulu. Okwesibini, izixhobo ze-Inp kunye ne-InP Zombini zine-velocity ephezulu ye-elektroni ye-Electroni, kunye ne-Eledron ye-Electron ye-Electron Drift imalunga ne-1 × 107 cm / s. Kwangelo xesha, i-Ingaas kunye nezixhobo ze-InP zineziphumo ze-elektroni ye-Elecloroot ephantsi kwentsimi yombane. I-Overshoot velocity inokwahlulwa ibe yi-4 × 107cm / s kunye ne-6 × 107cm / i-S, i-bandwidth enkulu. Okwangoku, i-Ingaas Popitectetectetect yeyona ndlela iphambili kunxibelelwano lwekhephu, kunye nendlela yokudibanisa i-thermling isetyenziswa kakhulu kwimarike, kunye ne-25 ye-GBAUD / i-56 GBAUD / i-GBAUD / ye-GBAUD / ye-GBAUD / ye-GBAUD / ye-GBAUD / i-GBAUD / ye-GBAUD / ye-GBAUD / ye-GBAUD / ye-GBAUD / ye-GEBAUD. Ubungakanani obuncinci, izehlo ezingasemva kunye nezibonelelo ze-bandwidth engaphezulu kwe-bandwidth ziye zaphuhliswa, ezilungele isantya esiphezulu kunye nezicelo eziphezulu. Nangona kunjalo, iProjekthi yeNgxelo yoMphezulu inqunyelwe yimowudi yayo yokudibanisa kwaye kunzima ukudityaniswa nezinye izixhobo ze-Optoecki. Ke ngoko, ngokuphuculwa kweemfuno zohlangatye ze-Optoectrongs, i-waveguide idityaniswe neefoto ze-InTaas ngeNtsebenzo ebalaseleyo kwaye ilungele ukudityaniswa kweemodyuli ezingama-70 ze-GHZ kunye ne-110 GHZ ye-GHZ ye-GHZEAAS. Ngokwezixhobo ezahlukeneyo ze-substice, i-wapeguide inxibelelanisa i-fotoctor fotoctric Probe inokwahlulwa yangamacandelo amabini: i-IP kunye ne-SI. Isithambisi esine-pitamational kwi-InP Suprest inomgangatho ophezulu kwaye ilungele ukulungiswa kwezixhobo zokusebenza eziphezulu. Nangona kunjalo, izixhobo ezahlukeneyo ze-mismatches phakathi kwezixhobo ze-III ze-III, izixhobo ze-iInges kunye ne-SIORSE kunye ne-SIODS ekhulayo zikhokelela kwimpahla engentle okanye i-ulsm, kunye nentsebenzo yesixhobo esinegumbi elikhulu lokuphucula.
