Kulemba kwa Peking University kunapereka chipolopolo chambiri chopitilira

Kufufuza ku yunivesite kunapereka perovskite yopitiliraroseryaying'ono kuposa 1 lalikulu micron
Ndikofunikira kupanga chinthu chokhazikika cha serser ndi malo ochepera 1μm2 kuti mukwaniritse zogwiritsidwa ntchito zowononga mphamvu zogwiritsidwa ntchito povomereza magetsi (<10 FJ pang'ono). Komabe, monga kukula kwa chipangizo kumachepa, kutayika kwa mawonedwe ndi zakuthupi kumawonjezera kwakukulu, kotero kuti mukwaniritse chipangizo cha chida cha micron ndi kupondapo kwa maboti a laser ndizovuta kwambiri. M'zaka zaposachedwa, Halide Perovskite zida zalandila chisamaliro chochuluka m'munda wopitilira ma alarrs othamanga kwambiri chifukwa cha kuchuluka kwawo kwamphamvu kwambiri ndi katundu wapadera wa polaton polariton. Chipangizo cha Chipangizo cha Perovskite chopitilira Laser adanenedwa mpaka pano popitilira 10μm2, ndi a submic2, amafunikira kukokoloka kwamphamvu kwambiri.

Poyankha izi, kafukufuku wa Zhang qing kuchokera ku sukulu ya zinthu zam'manja ndi ukadaulo wa petrovskite yopanda ma cutrol kuti muchepetse ma cell a laser ndi malo otsika ngati 0.65μμμμμμμμμμμmy. Nthawi yomweyo, chithunzicho chikuwululidwa. Njira ya Intsuton Polaton ku Subminten Mopitirira molimbika mwachangu imamveka bwino, yomwe imapereka lingaliro latsopano pakukula kwa kagawo kakang'ono ka semiconductor Lasers. Zotsatira za phunziroli, zobatizidwa kuti "funde lopitilira muyeso limatambalala za Perovskite Lasers yokhala ndi chipangizo pansipa 1 μm2," adasindikizidwa posachedwa.

Mu ntchitoyi, inrikanc perovskite pepala lomwe limakonzedwa ndi saptero wa shorthere popindika ndi mankhwala opaka mankhwala. Zinawonedwa kuti kulumikizana kwamphamvu kwa zigawo za Perovski ndi khoma lam'mimba ma Placrovoty Placepons kutentha kwa firiji kudapangitsa kuti porsonic polaton. Kudzera maumboni angapo, monga mizere yopanda tanthauzo, kutalika kwa masinthidwe a eleatiation ndi malo ogwiritsira ntchito ma cysby osakira pang'ono, ndipo malo a chipangizocho ndi otsika ngati 0,65μμμμμμμμμmy. Nthawi yomweyo, idapezeka kuti khomo la Dubminteron Laser Laser likufanana ndi gwero la laseji yayikulu, ndipo amatha kukhala otsika (Chithunzi 1).

Chithunzi 1. Kupitilira mwamphamvu kwambirigwero la laser

Komanso, ntchitoyi imayang'ana zonse zonse komanso mwaluso, ndipo zimawulula makina a intraton-polar okhazikika a subminteron yopitilira ya laser. Kuphatikizika kwa Photon-Pukuton ku Submicron Perovskites kumapangitsa kuwonjezeka kwakukulu m'magulu omwe ali ndi zaka za m'ma 80, omwe amawonjezera mawonekedwe opeza kuti abweze zotayika. Izi zimapangitsanso gwero la Sublekskite Surmicron Purctor yokhala ndi mawonekedwe apamwamba kwambiri komanso mawonekedwe ochepera (Chithunzi 2). Makinawa amazindikiranso zatsopano pakukula kwa ma lasers ang'onoang'ono, otsika otsika potengera zida zina za Semiconductor.

Nyimbo Yiepeng, wophunzira 2022 Zioo kuchokera ku Sukulu ya Zithunzi Zakuthupi ndi ukadaulo wa Pevice University, ndiye wolemba woyamba wa pepala, ndipo yunivesite ya Peng ndi gawo loyamba la pepalalo. Zhang Qing ndi Xiong Qihua, Pulofesa wa sayansi ya sayansi ya Tsinghua, ndi olemba ofanana. Ntchitoyi idathandizidwa ndi dziko la National Floive Maziko a China ndi Mhejing Science maziko a achinyamata otchuka.
