Dab tsi yog qhov txawv ntawm LED thiab qhov diode?

1, Cov Qauv thiab Cov Cai Ua Haujlwm
LED
LED yog cov khoom siv semiconductor uas ncaj qha hloov hluav taws xob hluav taws xob mus rau lub teeb lub zog. Nws cov qauv tsim muaj P-hom semiconductor thiab N-hom semiconductor, tsim ib qho PN kev sib tshuam ntawm ob. Thaum ib qho hluav taws xob txuas mus rau PN kev sib tshuam, cov hluav taws xob hauv cheeb tsam N yuav hla cov txheej txheem depletion thiab nkag mus rau thaj tsam P, thaum lub qhov hauv cheeb tsam P yuav hla cov txheej txheem depletion thiab nkag mus rau hauv cheeb tsam N. Txoj kev no hu ua carrier txhaj. Cov electrons thiab qhov txhaj tshuaj rau hauv cheeb tsam sib txawv recombine nyob ze ntawm PN hlws ris, qhov chaw uas lawv recombine rau hauv atoms thiab tso tawm lub zog nyob rau hauv daim ntawv ntawm photons, tsim pom los yog ze-infrared teeb.
Qhov tob diode
Qhov diode yog cov khoom siv semiconductor uas ua haujlwm raws li lub hauv paus ntsiab lus ntawm quantum mechanical tunneling effect. Nws muaj ib tug khub ntawm cov doped PN junctions thiab ib tug khub ntawm undoped cheeb tsam, thiab nws tshwj xeeb feature yog hais tias thaum lub rov qab voltage nce mus rau ib tug tej yam degree, hluav taws xob quantum tunneling nyhuv tshwm sim. Lub sijhawm no, lub qhov diode poob nws qhov qub PN hlws ris diode cov yam ntxwv thiab nthuav tawm lub xeev tsis zoo, qhov uas qhov tsis kam txo nrog qhov nce voltage. Cov yam ntxwv tshwj xeeb tsis zoo no ua rau lub qhov diodes teb sai sai ntawm qhov tsis tshua muaj hluav taws xob.
2, Kev ua haujlwm zoo
LED
High luminous efficiency: LEDs tuaj yeem hloov hluav taws xob zoo rau hauv lub teeb lub zog, ua rau muaj kev ua haujlwm siab luminous.
Ntev lifespan: LEDs feem ntau muaj ib tug lifespan ntawm kaum tawm txhiab teev, deb tshaj li ib txwm lub teeb qhov chaw.
Muaj yeeb yuj: Los ntawm kev kho qhov muaj pes tsawg leeg thiab kev faib ua feem ntawm cov khoom siv semiconductor, LEDs tuaj yeem tso lub teeb ntawm cov xim sib txawv.
Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: LEDs muaj lub zog siv hluav taws xob tsawg thaum lub sijhawm ua haujlwm thiab tsis muaj cov khoom phom sij xws li mercury, ua rau lawv ib puag ncig zoo.
Qhov tob diode
Cov lus teb ceev ceev: Lub sij hawm teb ntawm qhov diodes yog luv heev, mus txog qib picosecond, nrog rau kev ua haujlwm ntau txog 100 gigahertz.
Cov yam ntxwv tsis zoo: Qhov diodes muaj cov yam ntxwv tsis zoo tiv thaiv, uas ua rau lawv ua lub luag haujlwm tseem ceeb hauv qee qhov tshwj xeeb circuits.
Kev siv hluav taws xob tsawg: Qhov diodes muaj kev siv hluav taws xob tsawg thiab tsim nyog rau kev siv xws li satellite microwave cov khoom siv uas yuav tsum tau siv hluav taws xob ntau.
Tsis zoo thermal stability: Piv rau lwm cov khoom siv semiconductor, qhov diodes muaj thermal stability tsis zoo, uas rau qee qhov txwv lawv cov ntawv thov ntau yam.
3, Daim ntawv thov teb
LED
LEDs tau siv dav hauv ntau qhov chaw vim lawv cov yam ntxwv ua tau zoo:
Teeb pom kev zoo: LED teeb pom kev zoo muaj qhov zoo ntawm kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev ua neej ntev, thiab tau dhau los ua qhov kev xaiv tseem ceeb hauv cov teb xws li teeb pom kev hauv tsev, teeb pom kev lag luam, thiab teeb pom kev lag luam.
Zaub: LED cov ntxaij vab tshaus muaj qhov zoo ntawm qhov ci ci, qhov sib txawv siab, thiab cov xim ci, thiab tau siv dav hauv TV, computer saib, billboards, thiab lwm yam.
Kev taw qhia thiab teeb liab: LEDs ua lub luag haujlwm tseem ceeb hauv cov teeb liab tsheb, qhov taw qhia teeb, thiab lwm yam xwm txheej.
Qhov tob diode
Qhov diodes yog siv rau hauv cov teb tshwj xeeb vim lawv cov lus teb ceev ceev thiab cov yam ntxwv tsis zoo
Kev kub ceev hloov: Tunnel diodes ua tau zoo nyob rau hauv high-speed hloov circuits thiab yog haum rau ultra high-speed hloov logic circuits, flip flops, thiab cia circuits.
Microwave circuits: Qhov diodes yog siv dav hauv microwave circuits xws li microwave amplifiers thiab oscillators.
Oscillators: Cov yam ntxwv siab ntawm qhov diodes ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev ua cov oscillators siab.
