PMN-PT Substrate Fa'amatalaga
PMN-PT substrate e faasino i se ata manifinifi po o le wafer faia i mea piezoelectric PMN-PT.E fai ma fa'avae lagolago po'o se fa'avae mo masini fa'aeletonika po'o le optoelectronic.
I le tulaga o le PMN-PT, o le mea'ai e masani lava o se mafolafola mafolafola mafolafola e mafai ona tupu pe teu ai ni fa'amea manifinifi po'o ni fausaga.PMN-PT substrates e masani ona faʻaaogaina e faʻapipiʻi ai masini e pei o piezoelectric sensors, actuators, transducers, ma le seleselega malosi.
O nei mea faʻapipiʻi e maua ai se faʻavae mautu mo le tuputupu aʻe poʻo le faʻapipiʻiina o faʻaopoopoga faʻapipiʻi poʻo fausaga, e mafai ai ona tuʻufaʻatasia meatotino piezoelectric o le PMN-PT i masini.E mafai ona fau ni masini fa'apitoa ma lelei e fa'amanuiaina ai mea mai mea fa'apitoa o le piezoelectric.
Oloa Fa'atatau
Lattice matching maualuga e faasino i le fa'aogaina po'o le fetaui o fausaga lattice i le va o mea eseese e lua.I le tulaga o le MCT (mercury cadmium telluride) semiconductor, maualuga lattice faʻafetaui e manaʻomia ona e faʻatagaina le tuputupu aʻe o tulaga maualuga, leai se faʻaletonu epitaxial layers.
O le MCT o se mea semiconductor tu'ufa'atasi e masani ona fa'aogaina i fa'amatalaga infrared ma masini ata.Ina ia faʻateleina le faʻatinoga o masini, e taua tele le faʻatupuina o le MCT epitaxial layers e fetaui lelei ma le fausaga lattice o le mea faʻavae o loʻo i lalo (e masani lava CdZnTe poʻo GaAs).
E ala i le ausiaina o lattice maualuga faʻafetaui, o le faʻaogaina tioata i le va o laulau e faʻaleleia atili, ma faʻaitiitia faʻaletonu ma faʻalavelave i le atinaʻe.O lenei mea e tau atu i le sili atu le lelei o le tioata, faʻaleleia le eletise ma mea faʻapitoa, ma faʻaleleia le faʻatinoga o masini.
E taua tele le fetauiga lattice maualuga mo faʻaoga e pei o ata infrared ma lagona, lea e oʻo lava i ni faʻaletonu laiti poʻo le le atoatoa e mafai ona faʻaleagaina ai le faʻatinoga o masini, e aʻafia ai mea e pei o le maʻaleʻale, faʻafanua faʻafanua, ma le faʻatusatusaina o faailo-i-leo.
