PMN-PT Substrate
Ibisobanuro
PMN-PT kristu izwiho kuba ifite ingufu nyinshi cyane zo guhuza amashanyarazi, coefficient ya piezoelectric, imbaraga nyinshi hamwe no gutakaza dielectric.

Ibisobanuro bya PMN-PT Ibisobanuro
PMN-PT substrate bivuga firime yoroheje cyangwa wafer ikozwe mubikoresho bya piezoelectric PMN-PT.Ikora nkibishingiro cyangwa umusingi wibikoresho bitandukanye bya elegitoroniki cyangwa optoelectronic.
Mu rwego rwa PMN-PT, substrate mubusanzwe ni igorofa iringaniye hejuru yuburyo bworoshye cyangwa imiterere ishobora gukura cyangwa kubikwa.PMN-PT isanzwe ikoreshwa muguhimba ibikoresho nka sensor ya piezoelectric, moteri, transducers, hamwe nisarura ryingufu.
Izi substrate zitanga urubuga ruhamye rwo gukura cyangwa gushira mubindi byiciro cyangwa ibyubaka, bigatuma imitungo ya piezoelectric ya PMN-PT yinjizwa mubikoresho.Ifoto yoroheje cyangwa ya wafer ya PMN-PT substrates irashobora gukora ibikoresho byoroshye kandi bikora neza byunguka ibikoresho byiza bya piezoelectric.
Ibicuruzwa bifitanye isano
Guhuza lattice ndende bivuga guhuza cyangwa guhuza imiterere ya lattice hagati yibikoresho bibiri bitandukanye.Mu rwego rwa semiconductor ya MCT (mercure cadmium telluride), guhuza lattice ndende birakenewe kuko itanga imikurire yubwiza buhanitse, butagira inenge epitaxial.
MCT ni ibikoresho bya semiconductor bikoreshwa mubisanzwe bikoreshwa mumashanyarazi ya infragre hamwe nibikoresho byerekana amashusho.Kugirango ibikorwa byinshi bigerweho, nibyingenzi gukura MCT epitaxial ibice bihuza neza nuburyo bwa lattice yibikoresho byibanze (mubisanzwe CdZnTe cyangwa GaAs).
Mugushika kumurongo muremure uhuza, kristu ihuza ibice byatejwe imbere, kandi inenge hamwe ningutu kuri interineti bigabanuka.Ibi biganisha ku bwiza bwa kristaline, kunoza amashanyarazi na optique, hamwe nibikorwa byongera ibikoresho.
Guhuza lattice ndende ningirakamaro kuri porogaramu nko gufata amashusho ya infragre na sensing, aho ndetse nudusembwa duto cyangwa udusembwa bishobora gutesha agaciro imikorere yibikoresho, bikagira ingaruka nko kubyumva, gukemura umwanya, hamwe nikigereranyo cyerekana urusaku.
