ʻO Optical Harmony: High Violet Chip e hoʻokūkū ai no ka Golden Globes 2015 Engineering

[kikokikona / 'enekinia LED Yue Motte] LED kahua pāʻani kukui hana a me ka noiʻi 'enekinia Institute (GGII) anaʻiʻikepili hōʻike i loko o 2015 ka LED epitaxial chip output e hiki 14.8 ieeeea? ʻO ka hapa mua o 2012 a hiki i 2015, ua piʻi iki ka awelika kumu kūʻai i ke kahawai, ua emi ke kumukūʻai huahana, e hōʻike ana ua komo ka ʻoihana i kahi hoʻokūkū maikaʻi. Ua hoʻonohonoho ʻia ke kumu kumu kiʻekiʻe kiʻekiʻe LED flood light chip, ʻike ʻia nā mea hana chip i kahi ala kūpono o ke ola. Ma waena o lākou, ʻekolu papa inoa o nā hui hou o New Harmony photoelectric (832,502), i ʻike pū ʻia no kāna mau hiʻohiʻona maikaʻi mau i ka foothold mākeke. backpfrontp harmony Ua hoʻokumu ʻia ʻo Optoelectronics i ka hopena o ka makahiki 2010, ua ʻike ʻo ia ma mua o ʻehā mau makahiki o ka hoʻomohala ʻana i lilo i mea nui a koʻikoʻi 1000W LED kahawai kukui ʻoihana upstream mea hoʻolako, me ka huli makahiki o 400 miliona yuan, ua lawe ʻia nā huahana ma waho. Ua hoʻomaka ka hui ma 2014 e hoʻomohala i ka chip violet kiʻekiʻe a me ka kūleʻa mua, ma o ka hoʻopaʻi mākeke a me ka hoʻomau mau ʻana o nā mea kūʻai aku, a ua holomua maikaʻi. Wahi a Xu Qi backpbackpfrontp harmony photovoltaic project manager, ʻo ka hui kiʻekiʻe-mana violet PSS sapphire substrate ma muli chip e ulu ana i kahi papa epitaxial, me ka hoʻohana ʻana i kahi kukui uila hou ʻano o PSS substrates, ʻelua ʻanuʻu ʻano e hoʻoponopono ai i ka pilikia o ka ulu maikaʻi ʻana o ka kristal. maikaʻi I kēia manawa, haʻahaʻa-wikiwiki ulu ʻekolu-dimensional, e hoʻomaikaʻi i ka maikaʻi aniani o ka papa epitaxial, hiki ke hōʻemi i ka nui o ka defect, hoʻomaikaʻi i ka pono quantum kūloko. backpfrontp Ma ka lima ʻē aʻe, hoʻohana ka chip i ka hoʻolālā zigzag quantum well, hoʻomaikaʻi i nā lua lua quantum i kaohi ʻana i nā mea lawe e hoʻomaikaʻi i ka hiki ke hoʻohui hou ʻia electron-hole, ua ʻōlelo hou ʻo Xu Qi i ka chip o ka papa N-type a me nā ʻano P-type doped miscellaneous. optimization, hana i ka N-type layer a me P-type layer e hoʻemi i ka absorption o ka violet, hiki ke hoʻomaikaʻi i ka pono o ke kukui violet. I mea e loaʻa ai ka kiʻekiʻe kiʻekiʻe hohonu UV LED bay kukui harmoniny photoelectric ho'āʻo hoʻi e lawe i ka non-polar a semi-polar plane ili epitaxial ulu 'ike loea i homogeneous GaN substrate, hapa hoopau i ka quantum Stark hopena induced polarization uila kahua. backpfrontp mai ka makeke pane, i ka lokahi o kona photovoltaic nā mea kūʻai mai ua oi māʻona me ka poni kiʻekiʻe-mana huahana, i hiki ke hoʻomaopopo pono i ka mea kūʻai mai pono, a me ke kū ana pāʻoihana manaʻo, e hoʻolako i ka hailona o ka 'ike loea lawelawe. backpfrontp manaʻolana mākou ʻaʻole hiki i kā mākou huahana ke ʻike wale i ka hoʻāʻo mākeke hiki ke lanakila i ka hoʻomaikaʻi ʻana o nā hoahana a me nā loea, lanakila i ka Golden Globe i kēia makahiki ʻenehana LED kukui alanui. Ua hōʻike ʻia ʻo Harmony photoelectric Xiangdong.
