Ka taea te whakamahi i ngā rauemi haurua-ā-ira hou, angiangi, ngohengohe hoki, hei hanga i ngā rauemi moroiti me ngā rauemi haurua-ā-ira hou.ngā taputapu nano optoelectronic
ngā āhuatanga, te matotoru o te torutoru noa o ngā nanometer, ngā āhuatanga whatu pai… I ako te kairīpoata mai i Te Whare Wānanga Hangarau o Nanjing kua whakaritea e te rōpū rangahau o te ahorangi o te Tari Ahupūngao o te kura he tioata mata iodide rua-ahu tino angiangi kounga teitei, ā, mā roto i taua mea ka tutuki te whakahaere i ngā āhuatanga whatu o ngā rauemi whakarewa whakawhiti rua-ahu, e whakarato ana i tētahi whakaaro hou mō te hanga pūtau rā menga kaitirotiro whakaahuaI whakaputaina ngā hua i roto i te putanga hou o te hautaka ā-ao Advanced Materials.
"Ko ngā nanopepa mata iodide tino angiangi kua whakaritea e mātou mō te wā tuatahi, ko te kupu hangarau ko 'ngā tioata PbI2 rua-ahu matotoru ātomi', he rauemi semiconductor tino angiangi me te matotoru o te torutoru noa o ngā nanometa." I kī a Sun Yan, te kaituhi tuatahi o te pepa me te kaitono tohu tākuta i Te Whare Wānanga Hangarau o Nanjing, i whakamahia e rātou te tikanga otinga ki te hanga, he iti rawa ngā whakaritenga taputapu me ngā painga o te māmā, te tere me te whai hua, ā, ka taea te whakatutuki i ngā hiahia o te whakarite rauemi nui me te hua nui. Ko ngā nanopepa mata iodide kua hangaia he āhua tapatoru, he āhua hexagonal rānei, he rahi toharite o te 6 microns, he mata maeneene me ngā āhuatanga whatu pai.
I whakakotahi ngā kairangahau i tēnei nanosheet tino angiangi o te iodide mata me ngā sulfide whakarewa whakawhiti rua-ahu, i hangaia ā-hangai, i whakatakotoria ngātahi, ā, i whiwhi i ngā momo heterojunctions rerekē, nā te mea he rerekē te whakaritenga o ngā taumata pūngao, nō reira ka rerekē ngā pānga o te iodide mata ki te mahi whatu o ngā sulfide whakarewa whakawhiti rua-ahu rerekē. Ka taea e tēnei hanganga roopu te whakapai ake i te pai o te māramatanga, e whai hua ana ki te hanga i ngā taputapu pēnei i ngā diode rama me ngā laser, e whakamahia ana i roto i te whakaaturanga me te rama, ā, ka taea te whakamahi i roto i te mara o ngā photodetectors mengā taputapu photovoltaic.
Mā tēnei whakatutukitanga ka taea te whakahaere i ngā āhuatanga whatu o ngā rauemi whakarewa whakawhiti-rua-ahu mā te mata iodide tino-angiangi. Ki te whakatauritea ki ngā taputapu hikohiko tuku iho e hangai ana ki ngā rauemi e hangai ana ki te silicon, he āhuatanga o tēnei whakatutukitanga ko te ngāwari, te moroiti me te nano. Nō reira, ka taea te whakamahi ki te whakarite i ngā mea ngāwari me te whakauru.ngā taputapu optoelectronicHe whānui te whakamahinga o tēnei mea i roto i te mara o ngā taputapu hiko moroiti me te nano, ā, e whakarato ana i tētahi whakaaro hou mō te hanga pūtau rā, ngā taputapu whakaahua me ērā atu mea.
