Kumzi mveliso we-semicondcuctor oqinileyo, egcina iimeko zemo engqongileyo ibalulekile kwiinkqubo ezisemgangathweni.Imolekyuli i-pitam pitaxy (MB)vacuum pipes yombhobho (i-VIP). Le bhlog iphonononga indima ebalulekileyo yeI-vipekwandiseni MbeIzicelo, ekugxininiseni ukusebenza kwawo kunye nokuthembeka.
Ukubaluleka kokupholisa i-mbe
Imolekyuli i-pitam pitaxy (MB)is a highly controlled method of depositing atomic layers on a substrate, essential for producing semiconductor devices like transistors, lasers, and solar cells. Ukufezekisa ngokuchanekileyo okufunekayo kwi-MBE, ukugcina amaqondo obushushu aphantsi afanelekileyo. Liquid nitrogen is often used for this purpose due to its extremely low boiling point of -196°C, ensuring that the substrates remain at the necessary temperatures during the deposition process.

IINGXAKI ZEMPHODI YOKUGQIBELA YOKUGQIBELA (VIP) kwi-MBE
Vacuum pipes yombhobho (i-VIP)Ngaba luphambili kuhambo olusebenzayo lwe-nitrogen yolwelo. These pipes are designed with a vacuum layer between two walls, significantly reducing heat transfer and maintaining the cryogenic temperature of liquid nitrogen as it travels from storage to the MBE system. Olu luyilo lunciphisa ilahleko ye-nitrogen yolwelo ngenxa yokuphuma kwamanzi, ukuqinisekisa ukubonelelwa okungagungqiyo kunye nokuthembeka kwi-MBICTUS.
UkusebenzisaI-vipngaphakathiinika izibonelelo ezininzi. Ilahleko yokutshiswa okuncitshisiweyo kuthetha ukuba i-nitrogen encinci ye-nitrogen iyafuneka, ukwehlisa iindleko zokusebenza kunye nokuphucula ukusebenza kakuhle. Ukongeza, ipropathi yokufakelwa kweI-vipIgalelo kwindawo ekhuselekileyo yokusebenza ngokunciphisa umngcipheko weflostbite kunye nezinye iingozi ezinxulumene nokuphatha izixhobo ze-crygenic.
Inkqubo yokuphucula inkqubo
I-vipiqinisekisa ukuba i-nitrogen ye-nitrogen ihlala inobushushu oguqukayo kuhambo lwayo ukuya kwi. Olu nzo luzinzo lubaluleke kakhulu ekugcineni iimeko ezingqongqo eziyimfuneko kwimveliso ye-semicondcuctonuct. Ngokuthintela ukuguquguquka kobushushu,I-vipinceda ekuveliseni iyunifomu engaphezulu kunye ne-demiconductor ye-semiconductor, yandisa umgangatho ngokubanzi kunye nokusebenza kweemveliso zokugqibela.

Okwangoku, le nkqubo isebenza kakuhle kwizixhobo ze-MBE kubavelisi abakhokelayo abanjenge-DCA, irayisi kunye ne-fermi. Ukufakwa kwe'Inkqubo ephambili iqinisekisa ukubonelela nge-nitrogen yolwelo, esebenzayo yokuphucula ukusebenza kunye nokuzinza kweenkqubo ze-MBE.
Ukuqukumbela
Kwicandelo le-semiconductor, ngakumbi kwi vacuum pipes yombhobho (i-VIP)Ingathandeki.I-vipI-vipItekhnoloji kunye neenkqubo eziphambili ezifana nezo ziphuhlisweUya kudlala indima ebalulekileyo ekufezekiseni iimfuno ezingqongqo zeshishini kunye nokuqhuba inkqubela phambili yexesha elizayo.
