Ngoko nangoko On

Ii-LED zibonelela ngokukhanya kwangoko xa zilayitiwe. Kodwa ukukhanya kwesintu kuthatha imizuzwana embalwa ukufudumala ngaphambi kokuba kukhanye ngokupheleleyo. Oku kubenza bagqibelele ukusetyenziswa kwizicelo apho kufuneka ukukhanya kwangoko. Umzekelo, iirobhothi kunye nezibane zikaxakeka.

Zisebenza njani ii-LEDs?

Ii-LED, okanye ii-diode ezikhupha ukukhanya, zi-semiconductors. Baye bayiguqula indlela esikhanyisa ngayo amakhaya, iiofisi, kunye nezitrato zethu. Kodwa zisebenza njani ii-LED? Makhe sihlolisise iziseko zeteknoloji ye-LED, kuquka ukuhamba kwe-electron, i-pn junctions, kunye nezinye ezininzi.

• Iziseko ze-Electron Flow

Ukuze siqonde indlela ii-LED ezisebenza ngayo, kufuneka siqale siqonde imigaqo esisiseko yokuhamba kwe-electron. Ii-electron ngamasuntswana ahlawuliswa kakubi. Zijikeleza i-nucleus ye-athomu. Kwezinye izinto, ezinjengeentsimbi, ii-electron zikhululekile ukuba zihambe-hamba. Ivumela ukuhamba kombane. Kwezinye izinto, ezifana ne-insulators, ii-electron zibotshelelwe ngokuqinileyo kwii-athomu zazo. Yaye azihambi ngokukhululekileyo.

Izinto zeSemiconductor zineempawu ezinomdla. Ziwela kwindawo ethile phakathi kwezo zetsimbi kunye nezithinteli. Ziyakwazi ukuqhuba umbane, kodwa iintsimbi zingcono. Nangona kunjalo, ngokungafaniyo ne-insulators, "zinokulungiswa" ukuqhuba umbane phantsi kweemeko ezithile. Le propati yenza i-semiconductors ilungele ukusetyenziswa kwizixhobo zombane.

• I-PN Junction kunye nendima ye-Semiconductor Materials

Imathiriyeli yeSemiconductor idlala indima ebalulekileyo ekukhupheni ukukhanya kwii-LEDs. I-silicon okanye i-germanium idla ngokusetyenziswa njengezixhobo ze-semiconductor kwii-LED. Ukubenza baqhube ngokwaneleyo ukuvelisa ukukhanya, kufuneka ungeze ukungcola kwizinto eziphathekayo kwinkqubo ebizwa ngokuba yi-doping.

I-Doping ibandakanya ukongeza ixabiso elincinci lokungcola kwizinto eziphathekayo ze-semiconductor ukutshintsha iimpawu zayo zombane. Kukho iindidi ezimbini zedoping: uhlobo lwe-n kunye nohlobo lwe-p. I-N-type doping ibandakanya ukongeza ukungcola okunee-electron ezongezelelweyo kwizinto eziphathekayo ze-semiconductor. Ezi electron zongezelelweyo zikhululeka ukuba zijikeleze kwizinto eziphathekayo. Idala intsalela yamasuntswana ahlawuliswa kakubi. I-P-type doping, kwelinye icala, ibandakanya ukongeza ukungcola okunee-electron ezimbalwa kune-semiconductor material. Oku kudala "imingxuma" kwizinto okanye kwiindawo apho i-electron ilahlekile. Le mingxunya ihlawuliswe ngokuqinisekileyo.

Xa i-p-type material ibekwe ecaleni kwe-n-type material, i-pn junction yenziwa. Kwi-junction, ii-electron ezigqithisileyo ezivela kwi-n-type material zigcwalisa imingxuma kwi-p-type material. Oku kudala ummandla wokunciphisa, okanye indawo engenazo ii-electron zamahhala okanye imingxuma. Lo mmandla wokunciphisa usebenza njengomqobo ekuhambeni kwangoku. Oku kuthintela ukuhamba kwee-electron ukusuka kwi-n-type material ukuya kwi-p-type material.

• Ukubaluleka kweDoping kunye nokuDalwa koMmandla wokunciphisa

Ukudala indawo yokuncipha kubalulekile ekusebenzeni kwe-LED. Xa i-voltage isetyenziswa kwi-pn junction, ibangela ukuba ii-electron ezikwi-n-type material zihambe ziye ngakwisiphambuka. Kwangaxeshanye, imingxuma kwizinto zohlobo lwe-p zihamba zisiya kwisidibaniso kwelinye icala. Xa ii-electron kunye nemingxuma zidibana kwindawo yokunciphisa, zidibanisa kwaye zikhulule amandla ngendlela yokukhanya.

Umsantsa wamandla umisela ubude obuchanekileyo bokukhanya okwenziwayo. Ilele phakathi kwebhendi yevalence kunye nebhendi yokuqhuba yemathiriyeli yesemiconductor. Apha, ibhendi yokuqhuba libhendi yamanqanaba omandla kwizinto ezinokuthi ii-electron zihlale xa zingabotshwanga kwi-athomu. Ngakolunye uhlangothi, ibhendi ye-valence yinqanaba lamandla eelektroni azalise xa ebotshelelwe kwi-athomu. Kwaye xa i-electron iwela kwi-conduction band ukuya kwi-valence band, ikhupha amandla njengefoton yokukhanya.

• I-Electroluminescence kunye nokuVeliswa kweeFotoni

I-Electroluminescence yinto ekhupha ukukhanya. Yinkqubo yokukhutshwa kokukhanya kwisixhobo ekuphenduleni umbane odlulayo kuyo. Kwimeko yeteknoloji ye-LED, inkqubo ye-electroluminescence iqhutyelwa ngaphakathi kwe-chip ye-LED.

I-LED sisixhobo se-semiconductor esikhupha ukukhanya xa i-voltage isetyenziswa kwii-terminals zayo. I-LED yenziwe nge-pn junction, ummandla apho i-semiconductors ezimbini zidibene. I-p-type semiconductor ine-carrier carrier (umngxuma). Ngelo xesha, i-semiconductor yohlobo lwe-n ine-carrier ye-negative charge (electron).

I-voltage ye-bias yangaphambili isetyenziswe kwi-pn junction ye-LED. Kwaye oku kubangela ukuba ii-electron zidibanise kunye nemingxuma ye-electron ukukhulula amandla njengeefotoni. Iifotoni ezenziweyo emva koko zihamba ngeemaleko ze-LED. Kwaye zikhupha kwisixhobo njengokukhanya okubonakalayo. Noko ke, umbala wokukhanya okukhutshiweyo, uxhomekeke kumandla eefoton. Oku kuhambelana namandla e-bandgap yezinto ezisetyenziswa kwi-LED. Ngokomzekelo, ii-LED ezibomvu zenziwe kwi-semiconductors kunye ne-bandgap ephantsi yamandla. Ngokwahlukileyo, ii-LED eziluhlaza kunye nohlaza zifuna i-semiconductors enezithuba eziphezulu zamandla. Itshathi engezantsi ikubonisa iisemiconductors ezifanelekileyo zemibala eyahlukeneyo yokukhanya kwii-LEDs-
