Selelekela ho semiconductor sa moloko oa boraro GaN le theknoloji e amanang le eona ea epitaxial

1. Li-semiconductor tsa moloko oa boraro

Theknoloji ea semiconductor ea moloko oa pele e ntlafalitsoe ho latela thepa ea semiconductor e kang Si le Ge. Ke motheo oa thepa bakeng sa nts'etsopele ea li-transistors le theknoloji ea potoloho e kopaneng. Thepa ea semiconductor ea moloko oa pele e thehile motheo oa indasteri ea elektroniki lekholong la bo20 la lilemo 'me ke thepa ea motheo bakeng sa theknoloji ea potoloho e kopaneng.

Lisebelisoa tsa semiconductor tsa moloko oa bobeli li kenyelletsa haholo-holo gallium arsenide, indium phosphide, gallium phosphide, indium arsenide, aluminium arsenide le metsoako ea tsona ea ternary. Lisebelisoa tsa semiconductor tsa moloko oa bobeli ke motheo oa indasteri ea tlhahisoleseling ea optoelectronic. Motheong ona, liindasteri tse amanang le tsona tse kang mabone, ponts'o, laser le photovoltaics li se li ntlafalitsoe. Li sebelisoa haholo theknolojing ea tlhahisoleseling ea sejoale-joale le indastering ea ponts'o ea optoelectronic.

Lisebelisoa tse emelang thepa ea semiconductor ea moloko oa boraro li kenyelletsa gallium nitride le silicon carbide. Ka lebaka la lekhalo la tsona le leholo la lebanta, lebelo le phahameng la ho kheloha ha li-elektrone, conductivity e phahameng ea mocheso, le matla a tšimo a ho senyeha ho hoholo, ke lisebelisoa tse loketseng bakeng sa ho lokisa lisebelisoa tsa elektroniki tse nang le matla a phahameng, maqhubu a phahameng le tahlehelo e tlase. Har'a tsona, lisebelisoa tsa matla a silicon carbide li na le melemo ea matla a mangata, tšebeliso e tlase ea matla, le boholo bo bonyenyane, 'me li na le menyetla e mengata ea ts'ebeliso likoloing tse ncha tsa matla, li-photovoltaics, lipalangoang tsa terene, big data, le masimo a mang. Lisebelisoa tsa Gallium nitride RF li na le melemo ea maqhubu a phahameng, matla a phahameng, bandwidth e pharaletseng, tšebeliso e tlase ea matla le boholo bo bonyenyane, 'me li na le menyetla e mengata ea ts'ebeliso puisanong ea 5G, Inthanete ea Lintho, radar ea sesole le masimo a mang. Ho phaella moo, lisebelisoa tsa matla tse thehiloeng ho gallium nitride li sebelisitsoe haholo tšimong ea motlakase o tlase. Ho feta moo, lilemong tsa morao tjena, lisebelisoa tse hlahang tsa gallium oxide li lebelletsoe ho theha tlatsetso ea tekheniki le mahlale a teng a SiC le GaN, 'me li na le menyetla e ka bang teng ea ts'ebeliso masimong a maqhubu a tlase le a motlakase o phahameng.

Ha ho bapisoa le thepa ea semiconductor ea moloko oa bobeli, thepa ea semiconductor ea moloko oa boraro e na le bophara bo pharaletseng ba lekhalo (bophara ba lekhalo la Si, thepa e tloaelehileng ea thepa ea semiconductor ea moloko oa pele, e ka ba 1.1eV, bophara ba lekhalo la GaAs, thepa e tloaelehileng ea thepa ea semiconductor ea moloko oa bobeli, e ka ba 1.42eV, 'me bophara ba lekhalo la GaN, thepa e tloaelehileng ea thepa ea semiconductor ea moloko oa boraro, e ka holimo ho 2.3eV), khanyetso e matla ea mahlaseli, khanyetso e matla ea ho senyeha ha tšimo ea motlakase, le khanyetso e phahameng ea mocheso. Lisebelisoa tsa semiconductor tsa moloko oa boraro tse nang le bophara bo boholo ba lekhalo la lekhalo li loketse haholo tlhahiso ea lisebelisoa tsa elektroniki tse hanyetsanang le mahlaseli, maqhubu a phahameng, matla a phahameng le bongata bo kopaneng. Ts'ebeliso ea tsona lisebelisoa tsa maqhubu a seea-le-moea tsa microwave, li-LED, li-laser, lisebelisoa tsa motlakase le masimo a mang li hohetse tlhokomelo e kholo, 'me li bontšitse menyetla e pharaletseng ea nts'etsopele puisanong ea mehala ea thekeng, li-grid tse bohlale, lipalangoang tsa terene, likoloi tse ncha tsa matla, lisebelisoa tsa elektroniki tsa bareki, le lisebelisoa tsa khanya ea ultraviolet le e putsoa-botala [1].
