Inkcazelo yeGe Substrate
I-substrate ye-Ge ibhekisa kwi-substrate eyenziwe nge-element germanium (Ge).I-Germanium yimathiriyeli ye-semiconductor eneempawu ezizodwa ze-elektroniki ezenza ukuba zilungele usetyenziso lwe-elektroniki kunye ne-optoelectronic.
Ii-substrates ze-Ge ziqhele ukusetyenziswa xa kusenziwa izixhobo zombane, ngakumbi kwicandelo lobuchwephesha be-semiconductor.Zisetyenziswa njengezinto ezisisiseko zokubeka iifilimu ezibhityileyo kunye neengqimba ze-epitaxial zezinye i-semiconductors ezifana nesilicon (Si).Ii-substrates ze-Ge zingasetyenziselwa ukukhulisa i-heterostructures kunye ne-compound semiconductor layers ezineepropathi ezithile zezicelo ezifana ne-high-speed transistors, i-photodetectors, kunye neeseli zelanga.
I-Germanium ikwasetyenziswa kwi-photonics kunye ne-optoelectronics, apho inokuthi isetyenziswe njenge-substrate yokukhulisa izixhobo ze-infrared (IR) kunye neelensi.Ii-substrates ze-Ge zineepropati ezifunekayo kwizicelo ze-infrared, ezifana noluhlu olubanzi lokuhambisa kwingingqi ye-infrared kunye neempawu ezibalaseleyo zomatshini kumaqondo aphantsi.
I-Ge substrates ine-lattice ehambelana ngokusondeleyo ne-silicon, ezenza zihambelane nokudibanisa ne-Si-based electronics.Oku kuhambelana kuvumela ukuveliswa kwezakhiwo ezixubileyo kunye nophuhliso lwezixhobo zombane kunye neefotonic eziphambili.
Isishwankathelo, i-substrate ye-Ge ibhekisela kwi-substrate eyenziwe nge-germanium, imathiriyeli ye-semiconductor esetyenziswa kwizicelo ze-elektroniki kunye ne-optoelectronic.Isebenza njengeqonga lokukhula kwezinye izinto ze-semiconductor, eyenza ukuveliswa kwezixhobo ezahlukeneyo kwimimandla yombane, i-optoelectronics kunye ne-photonics.
