Tanthauzo la Ge Substrate
Gawo la Ge limatanthawuza gawo lapansi lopangidwa ndi element germanium (Ge).Germanium ndi chida cha semiconductor chokhala ndi zida zapadera zamagetsi zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mitundu yosiyanasiyana yamagetsi ndi optoelectronic.
Ma substrates a Ge amagwiritsidwa ntchito kwambiri popanga zida zamagetsi, makamaka pankhani yaukadaulo wa semiconductor.Amagwiritsidwa ntchito ngati zida zoyambira poyika mafilimu opyapyala ndi zigawo za epitaxial za semiconductors zina monga silicon (Si).Ma substrates a Ge atha kugwiritsidwa ntchito kukulitsa ma heterostructures ndi magawo apawiri a semiconductor okhala ndi mawonekedwe apadera ogwiritsira ntchito monga ma transistors othamanga kwambiri, ma photodetectors, ndi ma cell a solar.
Germanium imagwiritsidwanso ntchito muzojambula ndi ma optoelectronics, komwe imatha kugwiritsidwa ntchito ngati gawo lapansi pakukulitsa zowunikira ndi magalasi a infrared (IR).Ma substrates a Ge ali ndi zinthu zofunika pakugwiritsa ntchito kwa infuraredi, monga kufalikira kwamitundu yosiyanasiyana m'chigawo chapakati cha infrared komanso makina abwino kwambiri pamatenthedwe otsika.
Ma substrates a Ge ali ndi mawonekedwe ofananirako a lattice ndi silicon, kuwapangitsa kuti azigwirizana ndi zida zamagetsi za Si.Kugwirizana kumeneku kumathandizira kupanga mapangidwe osakanizidwa komanso kupanga zida zapamwamba zamagetsi ndi zithunzi.
Mwachidule, gawo lapansi la Ge limatanthawuza gawo laling'ono lopangidwa ndi germanium, chinthu cha semiconductor chomwe chimagwiritsidwa ntchito pamagetsi ndi optoelectronic.Zimagwira ntchito ngati nsanja ya kukula kwa zipangizo zina za semiconductor, zomwe zimathandiza kupanga zipangizo zosiyanasiyana pamagetsi, optoelectronics ndi photonics.
