Hiki ke hoʻohana ʻia nā mea semiconductor hou lahilahi a palupalu e hana i nā micro a menā mea hana nano optoelectronic
nā pono, ka mānoanoa o kekahi mau nanometer wale nō, nā waiwai optical maikaʻi… Ua aʻo ka mea kākau moʻolelo mai ke Kulanui ʻenehana ʻo Nanjing ua hoʻomākaukau ka hui noiʻi o ke polopeka o ka ʻOihana physics o ke kula i kahi kristal iodide alakaʻi ʻelua-dimensional kiʻekiʻe loa, a ma o ia mea e hoʻokō ai i ka hoʻoponopono ʻana o nā waiwai optical o nā mea sulfide metala hoʻololi ʻelua-dimensional, e hāʻawi ana i kahi manaʻo hou no ka hana ʻana i nā cell solar a menā mea nānā kiʻiUa paʻi ʻia nā hualoaʻa ma ka puke pai honua ʻo Advanced Materials.
"ʻO nā nanosheets lead iodide ultra-thin a mākou i hoʻomākaukau ai no ka manawa mua, ʻo ka huaʻōlelo loea ʻo 'atomicically thick wide band gap two-dimensional PbI2 crystals', he mea semiconductor ultra-thin me ka mānoanoa o kekahi mau nanometers wale nō." Ua ʻōlelo ʻo Sun Yan, ka mea kākau mua o ka pepa a he moho doctoral ma ke Kulanui ʻenehana ʻo Nanjing, ua hoʻohana lākou i ke ʻano hoʻonā e synthesize, nona nā koi lako haʻahaʻa loa a he mau pono o ka maʻalahi, wikiwiki a me ka pono, a hiki ke hoʻokō i nā pono o ka hoʻomākaukau ʻana i nā mea nui a me nā mea kiʻekiʻe. Loaʻa i nā nanosheets lead iodide i synthesized ke ʻano triangular a hexagonal maʻamau, ka nui awelika o 6 microns, ka ʻili laumania a me nā waiwai optical maikaʻi.
Ua hoʻohui nā kānaka noiʻi i kēia nanosheet lahilahi loa o ka iodide alakaʻi me nā sulfides metala hoʻololi ʻelua-dimensional, i hoʻolālā ʻia e ke ʻano hana, hoʻopili pū iā lākou, a loaʻa nā ʻano heterojunctions like ʻole, no ka mea, ua hoʻonohonoho ʻia nā pae ikehu ma nā ʻano like ʻole, no laila hiki i ka iodide alakaʻi ke loaʻa nā hopena like ʻole i ka hana optical o nā sulfides metala hoʻololi ʻelua-dimensional like ʻole. Hiki i kēia ʻano hui ke hoʻomaikaʻi pono i ka pono luminous, kahi mea e kūpono ai i ka hana ʻana o nā mea e like me nā diode hoʻomālamalama a me nā lasers, i hoʻopili ʻia i ka hōʻike a me ke kukui, a hiki ke hoʻohana ʻia ma ke kahua o nā photodetectors a menā mea hana photovoltaic.
Hoʻomaopopo kēia hoʻokō i ka hoʻoponopono ʻana i nā waiwai optical o nā mea sulfide metala hoʻololi ʻelua-dimensional e ka iodide alakaʻi ultra-thin. Ke hoʻohālikelike ʻia me nā mea optoelectronic kuʻuna e pili ana i nā mea silicon-based, loaʻa i kēia hoʻokō nā ʻano o ka flexibility, micro a me nano. No laila, hiki ke hoʻopili ʻia i ka hoʻomākaukau ʻana o ka flexible a me ka hoʻohui ʻia.nā mea hana optoelectronicLoaʻa iā ia kahi manaʻolana noi ākea ma ke kahua o nā mea hana micro a me nano optoelectronic i hoʻohui ʻia, a hāʻawi i kahi manaʻo hou no ka hana ʻana i nā cell solar, nā photodetectors a pēlā aku.
