ʻO ka mea noiʻi ʻo Yang Liang pūʻulu noiʻi ma ka Suzhou Institute for Advanced Study ma ke Kulanui o ʻEpekema a me ʻenehana o Kina i kūkulu i kahi ala hou no ka hana ʻana o ka metala oxide semiconductor laser micro-nano manufacturing, ka mea i ʻike i ka paʻi ʻana i ka laser o nā hale semiconductor ZnO me ka submicron precision, a hui pū ʻia. ia me ka metala laser paʻi , no ka manawa mua i hōʻoia i ka integrated laser pololei kākau o microelectronic 'āpana a me nā kaapuni e like me diodes, triodes, memristors a me encryption kaapuni, pela e hoʻonui i nā hiʻohiʻona noi o ka laser micro-nano hana i ke kahua o microelectronics, ma. ʻO nā mea uila maʻalahi, nā mea ʻike kiʻekiʻe, Intelligent MEMS a me nā māla ʻē aʻe he mau manaʻo noi nui. Ua paʻi ʻia nā hopena noiʻi ma "Nature Communications" ma lalo o ke poʻo inoa "Laser Printed Microelectronics".
ʻO ka lolouila paʻi kahi ʻenehana hou e hoʻohana ana i nā ʻano paʻi no ka hana ʻana i nā huahana uila. Hoʻokō ia i nā ʻano o ka maʻalahi a me ka pilikino o ka hanauna hou o nā huahana uila, a e lawe mai i kahi hoʻololi ʻenehana hou i ka ʻoihana microelectronics. I loko o nā makahiki he 20 i hala iho nei, ua holomua ka paʻi inkjet, laser-induced transfer (LIFT), a i ʻole nā ʻenehana paʻi ʻē aʻe i mea e hiki ai ke hana i nā mea hana microelectronic organik a me ka ʻole o ka pono o kahi lumi maʻemaʻe. Eia nō naʻe, ʻo ka nui o ka hiʻohiʻona maʻamau o nā ʻano paʻi ma luna ma ke ʻano he ʻumi microns, a koi pinepine i kahi kaʻina hana ma hope o ke kaʻina hana, a i ʻole hilinaʻi i ka hui ʻana o nā kaʻina hana e hoʻokō ai i ka hana ʻana o nā mea hana. Hoʻohana ka ʻenehana hana ʻenehana laser micro-nano i ka launa ʻole ma waena o nā pulse laser a me nā mea waiwai, a hiki ke hoʻokō i nā hale hana paʻakikī a me ka hana hoʻohui ʻana o nā mea paʻakikī e hoʻokō ʻia e nā ʻano kuʻuna me ka pololei o <100 nm. Eia nō naʻe, ʻo ka hapa nui o nā hale hana micro-nano-fabricated laser i kēia manawa he mau mea polymer hoʻokahi a i ʻole nā mea metala. ʻO ka nele o nā ala kākau pololei laser no nā mea semiconductor he mea paʻakikī hoʻi ka hoʻonui ʻana i ka noi ʻana o ka ʻenehana hoʻoponopono laser micro-nano i ke kahua o nā mea microelectronic.
Ma kēia ʻatikala, ʻo ka mea noiʻi ʻo Yang Liang, me ka hui pū ʻana me nā mea noiʻi ma Kelemania a me Australia, ua hoʻomohala hou i ka paʻi laser ma ke ʻano he ʻenehana paʻi no nā mea uila hana, ʻike i ka semiconductor (ZnO) a me ka conductor ( Composite laser paʻi o nā mea like ʻole e like me Pt a me Ag). (Figure 1), a ʻaʻole koi i nā ʻanuʻu kaʻina hana ma hope o ke kaʻina hana kiʻekiʻe, a ʻo ka liʻiliʻi liʻiliʻi he <1 µm. Hiki i kēia holomua ke hana i ka hoʻolālā a me ka paʻi ʻana o nā conductors, semiconductors, a me ka hoʻonohonoho ʻana o nā mea insulating e like me nā hana o nā mea microelectronic, e hoʻomaikaʻi nui ana i ka pololei, ka maʻalahi, a me ka mana o ka paʻi ʻana i nā mea microelectronic. Ma kēia kumu, ua ʻike maikaʻi ka hui noiʻi i ke kākau pololei ʻana i ka laser i hoʻohui ʻia o nā diodes, memristors a me nā kaapuni hoʻopiʻi kino ʻole reproducible (Figure 2). Ua kūpono kēia ʻenehana me ka paʻi inkjet kuʻuna a me nā ʻenehana ʻē aʻe, a manaʻo ʻia e hoʻonui ʻia i ka paʻi ʻana i nā ʻano mea like ʻole P-type a me N-type semiconductor metal oxide, e hāʻawi ana i kahi ʻano hana hou no ka hana ʻana i ka paʻakikī, nui. nā mea hana microelectronic hana ʻekolu.
