Ingxoxo enzulu kunye neepropathi ezisebenzayo ze-PN Junction Semiconductor Dods
Njengeyona nto ibalulekileyo kwicandelo le-elektroniki, umsebenzi kunye nolwakhiwo lwe-PN Juncy Duncy ibalulekile ekuqondeni yonke intsimi ye-semicondcuctor.Eli nqaku lijolise ekucaciseni ngokwasemthethweni ukwakhiwa, imigaqo-siseko yokusebenza kunye nokubaluleka kwesi sixhobo se-semiconductor kwizicelo ezisebenzayo, ngakumbi isiphumo sokuqinisekiswa.Isakhiwo kunye nomgaqo-siseko wokuSebenza we-PN Junction AKUKHO BUYIBINI KULO MSEBENZI OWENZELAYO OLUFANELEKILEYO KWI-ELD WENDALO, kodwa nangabafundi abafuna ukuqonda imigaqo-siseko yobunzulu bamakhontshinti.
Iinkcukacha zokwakha ze-PN Junction Diode
I-Diode ye-PN ye-Diode idityaniswe ngohlobo lwe-semiconductor kunye nohlobo lwe-semicondcuctor.Ukudityaniswa kwezi zinto zimbini ze-semicondcuctor zenza i-PN Junction.Ukwenza lula ukuqonda, sihlala sichaza i-PN Juncs Deds kwireferensi yobume bemifanekiso emibini (a).Kolu sakhiwo, uhlobo lwe-semiconductor lusebenza njengesiseko, kwaye i-P-chwether semicondcuctor ayifakwanga kuyo.Ngaphaya koko, isakhiwo esinye esibonisiweyo esiboniswe kumzobo (b) sisimvo esithile secandelo le-AA 'kwi-10 (a).Ukongeza, inani (c) libonisa isimboli kunye nendlela yokuhamba kwayo ngoku ye-PN Junction Diode, ebonelela ngesiseko sokuqonda iimpawu zayo zombane.
Xa uvavanya iipropathi zayo zombane, i-IV (i-IVUkuqhubela phambili phambili, xa i-voltage elungileyo isetyenziswa kwi-Diode, ukunyusa okwangoku ngevolthi.Phantsi kwekhefu eguqukayo, oko kukuthi, xa kusetyenziswa i-voltage engalunganga, i-OKUKHO phantse iphantse ibe yi-zero, ebonisa iimpawu zokusebenza okungahambelaniyo kwi-PN Junction Diode.Nangona kunjalo, ukuba i-voltage engalunganga iyaqhubeka ikhula, i-Diode ingahlukana, ibangela ukwanda okuthe tyaba okwangoku, nto leyo ebaluleke kakhulu kwizikhundla zayo zombane.
Ukulungisa isiphumo se-PN Junction Diode
Enye yezona zicelo zibalulekileyo ze-PN Juncy Puncy Umsebenzi wazo wokuQotshelwa koQotshelwa, onokwazi ukuguqula ukutshintshiselana (i-AC) kwi-Directurey yangoku (DC).Ngesiphaluka seRecarifier eboniswe kumzobo (a), sinokujonga umgaqo-nkqubo wokulungiswa kwe-Shave: Xa i-inftage yengeniso iyodwa, iya kudlula kwi-Diode kwi-Wiltage, ngelixaI-voltage ayilunganga, okwangoku ayiyi kuhamba.Iziphumo zoku kulungiswa kwesiqingatha se-wave zinokuqhubela phambili ngamandla okudlula kunye namanye amacandelo, ekugqibeleni kufezekisa iziphumo ezizinzileyo ze-DC.
Ukutolikwa kunye nokuchasana kwemizobo yeqela leqela
Kwinkqubo yokuqonda ngokunzulu imigaqo-siseko ye-PN Junction Deods, iifayile zeqela le-Band Diagrams zibonelela ngendlela enomdla wokujonga kwaye uqonde indlela yokuziphatha kwe-electrons kwi-lemicondtors.Xa i-semicondtuctorctorthect ikwimeko entle, umzekelo, ukusebenzisa i-voltage ye-0.5V kwicala lasekunene kuya kuvelisa intsimi yombane kuya kuvelisa intsimi yombane, oko kubangela ukuba i-book band diagram ivele.Kule meko, iipateni zokuhamba ze-elektroni kunye nemingxunya zidlala indima ephambili kwiipropathi zombane ze-PN Junctions.I-elektroni ihamba ukuya kwinqanaba lamandla asezantsi, ngelixa imingxunya yenza okwahlukileyo.Inkqubo yabo yokuhamba kunye nokubuyiswa kwayo ichaphazela ngqo ukwenziwa kwenkqubo ye-PN Junction Diode.
Xa uxoxa nge-band yeqela leqela ngaphambi nasemva kokuqhayisa, singayiqonda ngcono indlela yengingqi ye-N iyonke, kunye nendlela owenziwa ngayo ii-elektroniki kunye nemingxunya.Ubukho bomaleko obugqwirha kubaluleke kakhulu kwiipropathi zombane ze-PN Junction.Ayichaphazeli ukuqhubela phambili kweDiode, kodwa ichaphazela intsebenzo yayo kwiivolthi ezahlukeneyo.
Ngohlalutyo olunzulu lwesakhiwo, iimpawu zombane kunye nokusetyenziswa kwe-PN Juncs Deds kwisekethe ze-Elektroniki, sinokuwuqonda ngcono umgaqo wokusebenza kunye nokusetyenziswa kwesixhobo esibalulekileyo se-semicondcuctor.Isifundo kunye nokusetyenziswa kwe-PN Juncs Duncy kuphela kolwazi olusisiseko kwiinjineli ze-elektroniki kunye nabachwephesha, kodwa kwanobutyebi obuxabisekileyo kuye nabani na onqwenela ukufumana ukuqonda okunzulu kweetekhnoloji ezinzulu zala maxesha.
