ʻO ka wehewehe Ge substrate
ʻO ka substrate Ge e pili ana i kahi pani i hana ʻia me ka element germanium (Ge).ʻO Germanium kahi mea semiconductor me nā waiwai uila kūʻokoʻa e kūpono ai i nā ʻano uila a me nā noi optoelectronic.
Hoʻohana pinepine ʻia nā substrates Ge i ka hana ʻana i nā mea uila, ʻoi aku ka nui o ka ʻenehana semiconductor.Hoʻohana ʻia lākou ma ke ʻano he kumu kumu no ka waiho ʻana i nā kiʻiʻoniʻoni lahilahi a me nā papa epitaxial o nā semiconductor ʻē aʻe e like me ke silicon (Si).Hiki ke hoʻohana ʻia nā substrates Ge no ka ulu ʻana i nā heterostructures a me nā papa semiconductor hui pū me nā waiwai kikoʻī no nā noi e like me nā transistors kiʻekiʻe, photodetectors, a me nā cell solar.
Hoʻohana pū ʻia ʻo Germanium i nā photonics a me optoelectronics, kahi hiki ke hoʻohana ʻia ma ke ʻano he substrate no ka ulu ʻana i nā mea ʻike infrared (IR) a me nā lens.Loaʻa i nā substrates Ge nā waiwai i koi ʻia no nā noi infrared, e like me ka laulā hoʻouna ākea ma ka ʻāpana waena-infrared a me nā waiwai mechanical maikaʻi loa i nā haʻahaʻa haʻahaʻa.
Loaʻa i nā substrates Ge kahi hoʻolālā lattice i hoʻohālikelike ʻia me ke silika, e hoʻohālikelike iā lākou no ka hoʻohui ʻana me nā mea uila Si-based.Hāʻawi kēia hoʻohālikelike i ka hana ʻana o nā hale hybrid a me ka hoʻomohala ʻana i nā mea uila uila a me nā kiʻi photonic.
I ka hōʻuluʻulu ʻana, ʻo kahi substrate Ge e pili ana i kahi substrate i hana ʻia me ka germanium, kahi mea semiconductor i hoʻohana ʻia i nā noi uila a me optoelectronic.He kahua ia no ka ulu ʻana o nā mea semiconductor ʻē aʻe, e hiki ai i ka hana ʻana o nā ʻano mea like ʻole i ka ʻoihana uila, optoelectronics a me photonics.
