Saamaynta diode silikoon carbide ee awooda sare leh ee sawir qaadaha PIN
Silicon carbide PIN diode-ka awoodda sare leh wuxuu had iyo jeer ahaa mid ka mid ah meelaha ugu kulul ee cilmi baarista qalabka korontada.diode-ka PIN waa diode crystal ah oo lagu dhisay sandwiching lakabka semiconductor gudaha ah (ama semiconductor leh xooga wasakh yar) inta u dhaxaysa gobolka P+ iyo gobolka n+.I ee ku jira PIN waa soo gaabinta Ingiriisi ee macnaha "dhexdhexaad ah", sababtoo ah suurtagal maaha in la jiro semiconductor saafi ah oo aan wasakh ahayn, markaa lakabka I ee diode PIN ee arjiga ayaa badan ama ka yar oo lagu qasay qadar yar oo P ah. -nooca ama N-nooca wasakhda.Waqtigan xaadirka ah, silikoon carbide PIN diode inta badan wuxuu qaataa qaab dhismeedka Mesa iyo qaab dhismeedka diyaaradda.
Marka inta jeer ee hawlgalka PIN diode uu dhaafo 100Mhz, saamaynta kaydinta dhawr sideyaal iyo saamaynta wakhtiga transit ee lakabka I, diode lumin saamaynta hagaajinta oo uu noqdo element impedance ah, oo qiimihiisu isbedbeddelo danab eexda.Marka eexda eber tahay ama eexda gadaal ka ah DC, caqabada ka jirta gobolka I aad buu u sarreeyaa.Eexda hore ee DC, gobolka I wuxuu soo bandhigayaa xaalad cakiran oo hoose oo ay ugu wacan tahay duritaanka side.Sidaa darteed, diode-ka PIN-ka waxaa loo isticmaali karaa sidii curiyaha is-hortaagga ah ee doorsooma, goobta mikrowave iyo kantaroolka RF, inta badan waa lagama maarmaan in la isticmaalo aaladaha beddelka si loo gaaro beddelka calaamadda, gaar ahaan qaar ka mid ah xarumaha xakamaynta calaamadaha soo noqnoqda, PIN diodes waxay leeyihiin heer sare. Awoodaha xakamaynta calaamadaha RF, laakiin sidoo kale si ballaaran ayaa loogu isticmaalaa isbeddelka wajiga, habeynta, xaddididda iyo wareegyada kale.
Silikoon carbide diode ee awoodda sare leh ayaa si weyn loogu isticmaalaa goobta korantada sababtoo ah sifooyinkeeda iska caabbinta korantada sare, inta badan waxaa loo isticmaalaa sida tuubada toosiyaha tamarta sare leh.Diode-ka PIN waxa uu leeyahay koronto burbursan oo sare oo rogaal celis ah VB, taasoo ay ugu wacan tahay lakabka doping-ga hooseeya ee dhexda oo qaadaya hoos u dhaca danabka.Kordhinta dhumucda aagga I iyo yaraynta xoogga doping-ka ee aagga Waxaan si wax ku ool ah u wanaajin karaa korantada burburka gadaale ee PIN diode, laakiin joogitaanka aagga waxaan hagaajin doonaa hoos u dhaca danabka hore ee VF ee aaladda oo dhan iyo waqtiga beddelka aaladda. ilaa xad, iyo diode ka samaysan walxaha silikoon carbide ayaa ka dhigi kara cilladahaas.Silikon carbide 10 jeer burburka muhiimka ah ee beerta koronto ee silikoon, sidaa darteed dhumucda silikoon carbide diode I aagga dhumucdiisuna waxay hoos u dhigi kartaa toban meelood meel tuubada silikon, iyadoo la ilaalinayo koronto burbursan, oo ay weheliso kuleylka wanaagsan ee agabka silikoon carbide , ma jiri doonto dhibaatooyin cad oo kuleyl ah, sidaas darteed awoodda sare ee silicon carbide diode waxay noqotey qalab aad u muhiim ah oo ka mid ah qalabka korontada ee casriga ah.
Sababo la xiriira qulqulka aadka u yar ee hadda jira iyo dhaq-dhaqaaqa side sare, silikoon carbide diodes ayaa soo jiidasho weyn u leh goobta ogaanshaha sawir-qaadista.Daqiiqada yar yar waxay yarayn kartaa hadda mugdiga ah ee qalabka wax qabad waxayna yarayn kartaa qaylada;Dhaqdhaqaaqa sidaha sare wuxuu si wax ku ool ah u wanaajin karaa dareenka silikon carbide PIN detector(PIN Photodetector).Sifooyinka awoodda sare leh ee silikoon carbide diodes waxay awood u siinaysaa baarayaasha PIN inay ogaadaan ilaha iftiinka xooggan oo si weyn loogu isticmaalo goobta bannaan.Silicon carbide diode awood sare leh ayaa fiiro gaar ah loo siiyay sababtoo ah sifooyinkeeda ugu fiican, cilmi-baaristeeda ayaa sidoo kale si weyn loo horumariyay.
