Umgaqo we-PECVD graphite boat kwi-solar cell (coating) | VET Energy
Okokuqala, kufuneka sazi i-PECVD (iPlasma Enhanced Chemical Vapor Deposition). I-Plasma kukuqina kokunyakaza kobushushu beemolekyuli zezinto. Ukungqubana phakathi kwazo kuya kubangela ukuba iimolekyuli zegesi zibe yi-ionized, kwaye izinto ziya kuba ngumxube we-fr...Funda ngokugqithisileyo -
Izithuthi ezintsha zamandla ziphumelela njani ekubhulekini okuncedisa ukucoca i-vacuum? | VET Energy
Izithuthi zamandla ezintsha azinazo iinjini zepetroli, ngoko ke zikwazi njani ukuphumeza ukuqhobosheka okuncediswa yi-vacuum ngexesha lokuqhobosheka? Izithuthi zamandla ezintsha ikakhulu zifumana uncedo lweebhuleki ngeendlela ezimbini: Indlela yokuqala kukusebenzisa inkqubo yokuqhoboshela i-vacuum booster yombane. Le nkqubo isebenzisa i-vac yombane...Funda ngokugqithisileyo -
Kutheni sisebenzisa iteyiphu ye-UV xa sisika i-wafer? | VET Energy
Emva kokuba i-wafer idlule kwinkqubo yangaphambili, ukulungiswa kwe-chip kugqityiwe, kwaye kufuneka inqunyulwe ukuze kwahlulwe ii-chips kwi-wafer, kwaye ekugqibeleni ipakishwe. Inkqubo yokusika i-wafer ekhethiweyo kwii-wafers ezinobukhulu obahlukeneyo nayo yahlukile: ▪ Ii-wafers ezinobukhulu obungaphezulu ...Funda ngokugqithisileyo -
Iphepha lokulwa le-wafer, yintoni omawuyenze?
Kwinkqubo ethile yokupakisha, kusetyenziswa izixhobo zokupakisha ezinee-coefficients ezahlukeneyo zokwandisa ubushushu. Ngexesha lenkqubo yokupakisha, i-wafer ibekwa kwi-substrate yokupakisha, emva koko kwenziwa amanyathelo okufudumeza nokupholisa ukuze kugqitywe ukupakisha. Nangona kunjalo, ngenxa yokungafani phakathi...Funda ngokugqithisileyo -
Kutheni izinga lokusabela kwe-Si kunye ne-NaOH likhawuleza kune-SiO2?
Kutheni izinga lokusabela kwe-silicon kunye ne-sodium hydroxide linokudlula elo le-silicon dioxide lingahlalutywa kwezi nkalo zilandelayo: Umahluko kumandla e-chemical bond ▪ I-reaction ye-silicon kunye ne-sodium hydroxide: Xa i-silicon isabela kunye ne-sodium hydroxide, amandla e-Si-Si bond phakathi kwe-silicon ato...Funda ngokugqithisileyo -
Kutheni i-silicon ilukhuni kangaka kodwa ibuthathaka kangaka?
I-Silicon yikristale yeathomu, eneathomu ezidityaniswe ngezibopho ze-covalent, ezenza isakhiwo senethiwekhi yendawo. Kolu lwakhiwo, iibhondi ze-covalent phakathi kweeathomu zijolise kakhulu kwaye zinamandla aphezulu ebhondi, nto leyo eyenza i-silicon ibonise ubunzima obuphezulu xa imelana namandla angaphandle...Funda ngokugqithisileyo -
Kutheni iindonga ezisecaleni zigoba xa kugrunjwa okomileyo?
Ukungafaneli kwe-ion bombardment Ukugrumba okomileyo kudla ngokuba yinkqubo edibanisa iziphumo zomzimba nezekhemikhali, apho i-ion bombardment iyindlela ebalulekileyo yokugrumba ngokwasemzimbeni. Ngexesha lenkqubo yokugrumba, i-engile yesiganeko kunye nokusasazwa kwamandla kwee-ions kunokungalingani. Ukuba i-ion incide...Funda ngokugqithisileyo -
Intshayelelo kwiiteknoloji ezintathu eziqhelekileyo ze-CVD
Ukufakwa komphunga wekhemikhali (i-CVD) yeyona teknoloji isetyenziswa kakhulu kwishishini le-semiconductor ukufaka izinto ezahlukeneyo, kubandakanya uluhlu olubanzi lwezinto zokukhusela, uninzi lwezinto zesinyithi kunye nezinto ze-alloy zesinyithi. I-CVD yiteknoloji yendabuko yokulungiselela ifilimu encinci. Isiseko sayo...Funda ngokugqithisileyo -
Ngaba idayimani ingatshintsha ezinye izixhobo ze-semiconductor ezinamandla aphezulu?
Njengesiseko sezixhobo ze-elektroniki zanamhlanje, izixhobo ze-semiconductor zitshintsha ngendlela engakaze ibonwe ngaphambili. Namhlanje, idayimani ibonakalisa kancinci kancinci amandla ayo amakhulu njengezixhobo ze-semiconductor zesizukulwana sesine kunye neempawu zayo zombane kunye nobushushu obuhle kunye nozinzo phantsi koxinzelelo olukhulu...Funda ngokugqithisileyo
