Whakaahuatanga Poto:

Ko ngā Ingota LiTaO3 (Ingota Lithium Tantalate), hei rauemi matua mō ngā semiconductors whānui-bandgap me ngā optoelectronics o te whakatupuranga tuatoru, ka whakamahi i tō rātou pāmahana Curie teitei (607°C), whānuitanga māramatanga whānui (400–5,200 nm), tauwehenga hononga hikohiko tino pai (Kt² >15%), me te ngaronga dielectric iti (tanδ <2%) hei huri i ngā whakawhitiwhitinga 5G, te rorohiko irahiko, me te whakaurunga photonic. Mā roto i ngā hangarau hanga matatau pēnei i te kawe kohu tinana (PVT) me te whakatakotoranga kohu matū (CVD), ka whakaratohia e mātou ngā ingota tapahi-X/Y/Z, tapahi-42°Y, me ngā poro ā-wā (PPLT) i roto i ngā whakatakotoranga 3–8-inihi, e whakaatu ana i te kiato micropipe <0.1 cm⁻² me te kiato nekehanga <500 cm⁻². Kei roto i ā mātou ratonga te tāpiri Fe/Mg, ngā arataki ngaru whakawhiti proton, me te whakaurunga heterogeneous (POI) e hangai ana ki te silicon, e aro ana ki ngā tātari whatu mahi-teitei, ngā puna mārama irahiko, me ngā pūoko infrared. Ka akiakihia e tēnei rauemi ngā putanga hou i roto i te whakaitiiti, te mahi auau-teitei, me te pumau wera, te whakateretere i te whakakapinga ā-whare me te ahunga whakamua hangarau.
