SiGe phofo, e tsejoang hape e lesilicon germanium phofo, ke boitsebiso bo fumaneng tlhokomelo e kholo tšimong ea theknoloji ea semiconductor.Sengoliloeng sena se ikemiselitse ho bontša lebakaSiGee sebelisoa haholo lits'ebetsong tse fapaneng mme e hlahloba thepa le melemo ea eona e ikhethang.
Silicon germanium phofoke lintho tse entsoeng ka motsoako o entsoeng ka silicon le liathomo tsa germanium.Motsoako oa likarolo tsena tse peli o theha thepa e nang le thepa e tsotehang e sa fumaneheng ka silicon e hloekileng kapa germanium.E 'ngoe ea mabaka a ka sehloohong a ho sebelisaSiGeke ho lumellana ha eona ho babatsehang le mahlale a thehiloeng ho silicon.
Ho kopanyaSiGeho lisebelisoa tse thehiloeng ho silicon e fana ka melemo e mengata.E 'ngoe ea melemo e ka sehloohong ke bokhoni ba eona ba ho fetola thepa ea motlakase ea silicon, kahoo e ntlafatsa ts'ebetso ea likarolo tsa elektronike.Ha e bapisoa le silicon,SiGee na le elektrone e phahameng le motsamao oa lesoba, e lumellang ho tsamaisa elektronike ka potlako le lebelo le eketsehileng la sesebelisoa.Thepa ena e molemo ka ho khetheha bakeng sa lits'ebetso tsa maqhubu a phahameng, joalo ka litsamaiso tsa puisano tse se nang mohala le li-circuits tse kopantsoeng ka lebelo le holimo.
Ho feta moo,SiGee na le lekhalo le tlase la sehlopha ho feta silicon, e e lumellang ho monya le ho ntša khanya ka katleho.Thepa ena e etsa hore e be thepa ea bohlokoa bakeng sa lisebelisoa tsa optoelectronic tse kang photodetectors le light-emitting diodes (LEDs).SiGee boetse e na le conductivity e ntle ea mocheso, e e lumellang hore e felise mocheso hantle, e etsa hore e be e loketseng bakeng sa lisebelisoa tse hlokang tsamaiso e nepahetseng ea mocheso.
Lebaka le leng laSiGeTšebeliso e atileng ke ho lumellana ha eona le lits'ebetso tse teng tsa tlhahiso ea silicon.SiGe phofoe ka tsoakoa habonolo le silicon ebe e kenngoa holim'a silicon substrate e sebelisa mekhoa e tloaelehileng ea tlhahiso ea semiconductor e kang chemical vapor deposition (CVD) kapa molecular beam epitaxy (MBE).Kopanyo ena e se nang moeli e etsa hore e be le litšenyehelo tse ngata 'me e netefatsa phetoho e thellang bakeng sa bahlahisi ba seng ba thehile lisebelisoa tsa tlhahiso ea silicon.
SiGe phofoe ka boela ea etsa silicon e tsitsitsoeng.Mathata a bōptjoa ka lera la silicon ka ho beha lesela le tšesaane laSiGeka holim'a silicon substrate ebe o khetha ho tlosa liathomo tsa germanium.Mofuta ona o fetola sebopeho sa sehlopha sa silicon, se ntlafatsa le ho ntlafatsa thepa ea eona ea motlakase.Silicon e tsitsitsoeng e fetohile karolo ea bohlokoa ho li-transistors tse sebetsang hantle, tse nolofalletsang lebelo la ho chencha ka potlako le tšebeliso e tlase ea matla.
Holim'a moo,SiGe phofoe na le lisebelisoa tse ngata tse fapaneng tšimong ea lisebelisoa tsa thermoelectric.Lisebelisoa tsa thermoelectric li fetola mocheso hore e be motlakase le ka tsela e fapaneng, e leng se etsang hore e be tsa bohlokoa lits'ebetsong tse kang ho fehla motlakase le lisebelisoa tsa ho pholisa.SiGee na le ts'ebetso e phahameng ea mocheso le thepa ea motlakase e ka sebelisoang, e fana ka thepa e loketseng bakeng sa nts'etsopele ea lisebelisoa tse sebetsang hantle tsa thermoelectric.
Ha re phethela,SiGe phofo or silicon germanium phofoe na le melemo le lits'ebetso tse fapaneng lefapheng la theknoloji ea semiconductor.Ho lumellana ha eona le mekhoa e teng ea silicon, thepa e babatsehang ea motlakase le conductivity ea mocheso e etsa hore e be thepa e ratoang.Hore na ho ntlafatsa ts'ebetso ea li-circuits tse kopaneng, ho nts'etsapele lisebelisoa tsa optoelectronic, kapa ho theha lisebelisoa tse sebetsang hantle tsa thermoelectric,SiGee tsoela pele ho paka bohlokoa ba eona e le thepa e sebetsang ka bongata.Ha lipatlisiso le theknoloji li ntse li tsoela pele, re lebeletseSiGe powdersho bapala karolo ea bohlokoa le ho feta ho bopeng bokamoso ba lisebelisoa tsa semiconductor.
