PMN-PT Substrate Tlhaloso
PMN-PT substrate e bua ka filimi e tšesaane kapa sephaphatha se entsoeng ka thepa ea piezoelectric PMN-PT.E sebetsa e le motheo kapa motheo oa lisebelisoa tse fapaneng tsa elektroniki kapa tsa optoelectronic.
Sebakeng sa PMN-PT, substrate hangata ke sebaka se bataletseng se thata moo likarolo kapa meaho e mesesaane e ka holisoang kapa ea beoa.Li-substrates tsa PMN-PT li atisa ho sebelisoa ho etsa lisebelisoa tse kang li-piezoelectric sensors, actuators, transducers, le lisebelisoa tsa ho kotula matla.
Li-substrates tsena li fana ka sethala se tsitsitseng bakeng sa ho hōla kapa ho behoa ha lihlopha tse eketsehileng kapa mehaho, e lumellang hore thepa ea piezoelectric ea PMN-PT e kenngoe ho lisebelisoa.Sebopeho sa filimi e tšesaane kapa sephaephe sa li-substrates tsa PMN-PT se ka etsa lisebelisoa tse sebetsang hantle le tse sebetsang hantle tse ruang molemo ka thepa e ntlehali ea piezoelectric.
Lihlahisoa tse Amanang
Ho nyallana ha lithapo tse phahameng ho bolela ho tsamaisana kapa ho nyallana ha meaho ea mapolanka lipakeng tsa lisebelisoa tse peli tse fapaneng.Boemong ba li-semiconductors tsa MCT (mercury cadmium telluride), ho lumellana le li-lattice tse phahameng hoa lakatseha hobane ho lumella ho hōla ha likarolo tsa epitaxial tsa boleng bo phahameng, tse se nang sekoli.
MCT ke lisebelisoa tse kopantsoeng tsa semiconductor tse sebelisoang hangata ho li-detectors tsa infrared le lisebelisoa tsa litšoantšo.Ho eketsa ts'ebetso ea sesebelisoa, ho bohlokoa ho holisa MCT epitaxial layers e ts'oanang hantle le sebopeho sa lattice sa thepa e ka tlase ea substrate (hangata CdZnTe kapa GaAs).
Ka ho finyella boemo bo phahameng ba marang-rang, ho lumellana ha kristale pakeng tsa lihlopha ho ntlafatsoa, 'me mefokolo le khatello ho sebopeho li fokotsehile.Sena se lebisa ho boleng bo betere ba kristale, thepa e ntlafalitsoeng ea motlakase le ea optical, le ts'ebetso e ntlafalitsoeng ea lisebelisoa.
Ho lumellana ho phahameng ho bohlokoa bakeng sa lits'ebetso tse kang infrared imaging le sensing, moo esita le likoli tse nyane kapa mefokolo e ka theolang ts'ebetso ea sesebelisoa, e ama lintlha tse joalo ka kutlo, tharollo ea sebaka, le karo-karolelano ea lerata.
