O le fa'auigaga o le substrate Ge
O le Ge substrate e faasino i se mea e fai i le elemene germanium (Ge).Germanium o se mea semiconductor faʻatasi ai ma mea faʻaeletoroni tulaga ese e faʻaogaina ai le tele o faʻaoga eletise ma optoelectronic.
Ge substrates e masani ona faʻaaogaina i le gaosiga o masini faʻaeletoroni, aemaise lava i le fanua o tekinolosi semiconductor.E faʻaaogaina e fai ma mea faʻavae mo le teuina o ata manifinifi ma epitaxial layers o isi semiconductors e pei o le silicon (Si).Ge substrates e mafai ona faʻaogaina e faʻatupuina ai heterostructures ma faʻapipiʻi vaega semiconductor faʻatasi ma mea faʻapitoa mo faʻaoga e pei o transistors maualuga-saosaoa, photodetectors, ma sela sola.
O le Germanium e faʻaaogaina foi i photonics ma optoelectronics, lea e mafai ona faʻaaogaina e fai ma mea e faʻaogaina mo le faʻatupulaia o faʻamaʻi (IR) ma tioata.Ge substrates ei ai meatotino e manaʻomia mo faʻaoga infrared, e pei o le lautele o felauaiga i totonu o le ogatotonu o le infrared ma mea faʻainisinia sili ona lelei i le maualalo o le vevela.
Ge substrates o loʻo i ai se fausaga lattice vavalalata faʻatusa i le silikoni, e faʻafetaui ai mo le tuʻufaʻatasia ma mea faʻaeletonika faʻavae Si.O lenei fesoʻotaʻiga e faʻatagaina ai le fausiaina o fausaga faʻapipiʻi ma le atinaʻeina o masini eletise ma photonic.
I le aotelega, o le Ge substrate e faʻatatau i se mea faʻapipiʻi e faia i le germanium, o se mea semiconductor faʻaaogaina i mea faʻaeletoroni ma optoelectronic.E avea o se faʻavae mo le tuputupu aʻe o isi mea semiconductor, e mafai ai ona faʻapipiʻiina masini eseese i le fanua o mea tau eletise, optoelectronics ma photonics.
