Kaminuza ya Peking yamenye ko perovskite ikomezaInkomoko ya Laserntoya kurenza micron
Ni ngombwa kubaka Inkomoko ya Laser ikomeza hamwe nigikoresho kiri munsi ya 1μm2 kugirango yuzuze ibisabwa byingufu nkeya ya Op-Chip Optique Opt-1). Ariko, mugihe ingano yibikoresho iragabanuka, gutakaza ibitekerezo no kwiyongera kwiyongera cyane, kuburyo igera kuri spor-micron igikoresho cyigikoresho cya laser hamwe nibihuha bya laser biragoye cyane. Mu myaka yashize, ibikoresho bya Perovskite byakiriye neza murwego rwo gukomeza amapote akomeza kuba impande zose ziterwa nubwitonzi bwabo bwo hejuru hamwe nibiranga bidasanzwe. Agace k'ibikoresho bya Perovskite gakomeza gukurikiranwa laser byatangajwe kugeza ubu biracyaruta kuri 10μm2 amasoko yose bisaba urumuri rwinshi rwo gusunika imbaraga zo gukangura.

Mu gusubiza iki kibazo, itsinda ryubushakashatsi rya Zhang Qing kuva mwishuri ryubumenyi nubwubatsi bwa kaminuza ya Peking yatsinze neza. Muri icyo gihe, hagaragaye photon. Uburyo bwa extaim Polariton muri Submicron ikomeza guhagarika inzira itabura byumvikana, bitanga igitekerezo gishya cyo guteza imbere ubunini buto bwa ecincenductor. Ibisubizo by'ubushakashatsi, bwihanganye "umuraba uhoraho wa Perovskite Lasers ifite ibikoresho bigezweho.

Muri iki gikorwa, muri inoristanic perovskite cskbbb3 imwe ya kristu ya kirisiti yateguwe kuri safiro ya sapfire na chique vapor. Byagaragaye ko guhuza gukomeye k'urukuta rwa Perovskite hamwe na microCavity MicroCavity Gufotora ku bushyuhe bw'icyumba byatewe no gushinga polariton. Binyuze mu ruhererekane rw'ibimenyetso, nk'imirongo yo kunyuramo bidahwitse, umurongo muto wo guhinduranya, kandi ibikoresho byo guhinduranya ibicuruzwa byemejwe, kandi igikoresho kimwe cya kirimbuzi kirakemo. Muri icyo gihe, byagaragaye ko urwego rwinkomoko ya submicroron laser agereranywa nikintu kinini cya laser claser, kandi gishobora no kuba munsi (Ishusho 1).

Igishushanyo 1. Gukomeza Indangantego ya Submirdron CSPBBR3Inkomoko ya Laser

Byongeye kandi, iyi mirimo irashakisha mubushakashatsi kandi mubyukuri, kandi ihishura uburyo bwo gutanga amanota azwi mu kugera kubikorwa bya SubmicroR ikomeza kuba laser. Kwiyongera kwa Photon-excitin muri Submirron PAROVSKItes bivamo ubwiyongere bukomeye muri 80 yorohereza ibintu kugeza kuri 80, byongera byinshi muburyo bwo kwishyura kugirango ubone igihangange. Ibi kandi bivamo submicron submicron laser inkomoko hamwe nibintu byiza byimiterere hamwe numuyoboro wanyuma wanyuma (Ishusho 2). Urwego rutanga kandi ubushishozi bushya mugutezimbere ubunini buto, abanyamaguru-hasi bashingiye kubindi bikoresho bya semiconductor.

Igishushanyo cya 2. Uburyo bwa Sub-Micron Laser Inkomoko ukoresheje Udubujije

Indirimbo Jiepeng, umunyeshuri wa Zhibo 2020 wo mu ishuri ry'ibikoresho siyanse n'ubwubatsi bwa kaminuza ya paki, ni umwanditsi wa mbere w'impapuro, kandi wa kaminuza ya peking nigice cyambere cyimpapuro. Zhang Qing na Xiong Qihua, Porofeseri wa fiziki muri kaminuza ya Tsinghua, ni abanditsi bahuye. Akazi kashyigikiwe na siyanse y'igihugu y'Ubushinwa na siyansi ya Beijing Fondasiyo idasanzwe y'urubyiruko.
