Ibikoresho bito kandi byoroshye ibikoresho bya semiconductor birashobora gukoreshwa mugukora micro na nano optoelectronic ibikoresho

Ibikoresho byoroheje kandi byoroshye ibikoresho bya semiconductor birashobora gukoreshwa mugukora micro naibikoresho bya nano optoelectronic

roperties, ubunini bwa nanometero nkeya gusa, ibintu byiza bya optique… Umunyamakuru yize muri kaminuza y’ikoranabuhanga ya Nanjing ko itsinda ry’ubushakashatsi ry’umwarimu w’ishami ry’ubugenge ry’iri shuri ryateguye ultr-thin-high-quality-yo mu rwego rwo hejuru ya sisitemu yo mu bwoko bwa iyode ya kirisitu, kandi binyuze muri yo kugira ngo igere ku mabwiriza ya optique y’ibikoresho bya sulfide y’ibice bibiri, bitanga igitekerezo gishya cyo gukora ingirabuzimafatizo zikomoka ku zuba.gufotora. Ibisubizo byatangajwe mu nomero iheruka yikinyamakuru mpuzamahanga Advanced Materials.

"Ultra-thin lead iodide nanosheets twateguye ku nshuro ya mbere, ijambo tekinike ni 'atomike yuzuye umubyimba mugari utandukanya ibice bibiri bya kristu ya PbI2', ibyo bikaba ari ibikoresho bya semiconductor ultra-thin bifite uburebure bwa nanometero nkeya." Sun Yan, umwanditsi wa mbere w’uru rupapuro akaba n'umukandida wa dogiteri muri kaminuza y’ikoranabuhanga ya Nanjing, yavuze ko bakoresheje uburyo bwo gukemura kugira ngo bahuze, bufite ibikoresho bike cyane kandi bifite ibyiza byo koroshya, byihuse kandi neza, kandi bishobora guhaza ibikenewe mu turere twinshi kandi twiteguye gutanga umusaruro mwinshi. Sinteziside ya sisitemu iyode nanosheets ifite imiterere ya mpandeshatu cyangwa mpandeshatu, impuzandengo ya microne 6, ubuso bworoshye nibintu byiza bya optique.

Abashakashatsi bahujije iyi ultra-thin nanosheet ya sisitemu yo mu bwoko bwa iyode hamwe na sulfide y'ibyuma bibiri-byinzibacyuho, byakozwe mu buryo bwa gihanga, babishyira hamwe, kandi babona ubwoko butandukanye bwa heterojunctions, kubera ko ingufu zitunganijwe mu buryo butandukanye, bityo iyode iyobora irashobora kugira ingaruka zitandukanye ku mikorere ya optique ya sulfide itandukanye. Imiterere ya bande irashobora kunoza neza imikorere yumucyo, ifasha mugukora ibikoresho nka diode itanga urumuri na lazeri, bikoreshwa mukwerekana no kumurika, kandi birashobora gukoreshwa mubijyanye na fotodetekeri naibikoresho bifotora.

Ibi byagezweho bigena imiterere ya optique yibikoresho bibiri-byinzibacyuho byuma bya sulfide byifashishijwe na ultra-thin lead iodide. Ugereranije nibikoresho gakondo bya optoelectronic bishingiye kubikoresho bishingiye kuri silicon, iki cyagezweho gifite ibiranga guhinduka, micro na nano. Kubwibyo, irashobora gukoreshwa mugutegura ibintu byoroshye kandi byahujweibikoresho bya optoelectronic. Ifite ibyerekezo byinshi byo gusaba murwego rwibikoresho bya micro na nano optoelectronic ibikoresho, kandi bitanga igitekerezo gishya cyo gukora imirasire yizuba, fotodeteri nibindi.
