Nkọwapụta Ge Substrate

Mkpụrụ Ge na-ezo aka na mkpụrụ osisi germanium (Ge).Germanium bụ ihe semiconductor nwere akụrụngwa eletrọnịkị pụrụ iche nke na-eme ka ọ dabara maka ngwa elektrọnik na ngwa optoelectronic dị iche iche.

A na-ejikarị Ge substrates eme ihe n'ichepụta ngwa eletrọnịkị, ọkachasị na ngalaba teknụzụ semiconductor.A na-eji ha dị ka ihe ndabere maka itinye ihe nkiri dị mkpa na akwa epitaxial nke semiconductor ndị ọzọ dị ka silicon (Si).Enwere ike iji ihe mkpụrụ osisi na-eto eto heterostructures na ngwakọta semiconductor n'ígwé nwere akụrụngwa akọwapụtara maka ngwa dị ka transistors ọsọ ọsọ, fotodetector na sel anyanwụ.

A na-ejikwa Germanium na photonics na optoelectronics, ebe enwere ike iji ya dị ka ihe na-emepụta ihe nchọpụta infrared (IR) na lenses.Ge substrates nwere akụrụngwa achọrọ maka ngwa infrared, dị ka oke mgbasa ozi na mpaghara etiti infrared yana ezigbo igwe eji arụ ọrụ na obere okpomọkụ.

Ge substrates nwere usoro lattice dakọtara chiri anya na silicon, na-eme ka ha dakọtara maka njikọta na ngwa eletrọnịkị dabere na Si.Nkwekọrịta a na-enye ohere ịmepụta ihe owuwu ngwakọ na mmepe nke ngwaọrụ eletrọnịkị na fotonic dị elu.
