Researcher Yang Liang's research group na Suzhou Institute for Advanced Study na University of Science and Technology of China mepụtara usoro ọhụrụ maka metal oxide semiconductor laser micro-nano n'ichepụta, nke ghọtara laser obibi nke ZnO semiconductor owuwu na submicron nkenke, na jikọtara ya. ya na mbipụta laser metal, na nke mbụ kwadoro ederede laser kpọmkwem nke microelectronic components na sekit dị ka diodes, triodes, memristors na encryption circuits, si otú ịgbatị ngwa ndapụta nke laser micro-nano nhazi na ubi nke microelectronics, na eletrọnịkị na-agbanwe agbanwe, sensọ dị elu, MEMS nwere ọgụgụ isi na mpaghara ndị ọzọ nwere atụmanya ngwa dị mkpa.E bipụtara nsonaazụ nyocha n'oge na-adịbeghị anya na "Nature Communications" n'okpuru aha "Laser Printed Microelectronics".
Igwe eletrọnịkị ebi ebi bụ teknụzụ na-apụta nke na-eji ụzọ obibi akwụkwọ arụpụta ngwaahịa eletrọnịkị.Ọ na-ezute njirimara nke mgbanwe na nhazi nke ọgbọ ọhụrụ nke ngwaahịa eletrọnịkị, ma ga-eweta mgbanwe teknụzụ ọhụrụ na ụlọ ọrụ microelectronics.N'ime afọ 20 gara aga, mbipụta inkjet, nnyefe laser-induced (LIFT), ma ọ bụ usoro obibi akwụkwọ ndị ọzọ emeela nnukwu ọganihu iji mee ka ịmepụta ngwaọrụ microelectronic organic na inorganic na-arụ ọrụ na-enweghị mkpa maka ebe obibi dị ọcha.Otú ọ dị, ụdị njirimara nke usoro obibi akwụkwọ ndị dị n'elu na-abụkarị n'usoro nke iri microns, ma na-achọkarị usoro nhazi nke okpomọkụ dị elu, ma ọ bụ na-adabere na nchikota nke ọtụtụ usoro iji nweta nhazi nke ngwaọrụ arụ ọrụ.Laser micro-nano nhazi technology utilizes na nononlinear mmekọrịta n'etiti laser pulses na ihe, na ike nweta mgbagwoju ọtọ owuwu na mmako n'ichepụta nke ngwaọrụ ndị siri ike nweta site omenala ụzọ na a nkenke nke <100 nm.Otú ọ dị, ọtụtụ n'ime ihe owuwu laser micro-nano dị ugbu a bụ otu ihe polymer ma ọ bụ ihe ọla.Enweghị usoro ederede laser kpọmkwem maka ihe semiconductor na-emekwa ka o sie ike ịgbasa ngwa nke teknụzụ nhazi laser micro-nano na mpaghara nke ngwaọrụ microelectronic.
Na nke a tesis, na-eme nchọpụta Yang Liang, na imekọ ihe ọnụ na-eme nnyocha na Germany na Australia, innovatively mepụtara laser obibi akwụkwọ dị ka a na-ebi akwụkwọ technology maka ọtọ ngwá electronic, na-aghọta semiconductor (ZnO) na eduzi (Composite laser obibi nke dị iche iche ihe dị ka Pt na Ag).
