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

imigozi, umubyimba wa nanometero nkeya gusa, ibyiza bya optique… Umunyamakuru yize muri kaminuza y’ikoranabuhanga ya Nanjing ko itsinda ry’ubushakashatsi bw’umwarimu w’ishami ry’ubugenge ry’iri shuri ryateguye ultra-thin high-quality-quality-dimode-yode ya kirisiti , kandi binyuze muri yo kugirango igere ku mabwiriza ya optique yibikoresho bibiri-byinzibacyuho byuma byuma bya sulfide, bitanga igitekerezo gishya cyo gukora imirasire yizuba kandigufotora.Ibisubizo byatangajwe mu nomero iheruka yikinyamakuru mpuzamahanga Advanced Materials.

"Ultra-thin lead iodide nanosheets twateguye kunshuro yambere, ijambo tekinike ni 'atomike yubugari bwagutse bwa bande itandukanya ibice bibiri bya kristu ya PbI2', ni ibikoresho bya semiconductor ultra-thin bifite umubyimba wa 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 ibibazo kugira ngo bahuze, bufite ibikoresho bike cyane bikenerwa kandi bifite ibyiza byoroheje, byihuse kandi neza, kandi bishobora kuzuza U ibikenerwa ahantu hanini kandi bitanga umusaruro mwinshi wo gutegura ibikoresho.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 ya iyode hamwe na sulfide y'ibyuma bibiri-byinzibacyuho, byakozwe mu buryo bwa gihanga, babishyira hamwe, kandi babona ubwoko butandukanye bwa heterojunctions, kubera ko urwego rwingufu zitunganijwe muburyo butandukanye, bityo iyode irashobora kugira ingaruka zitandukanye. kumikorere ya optique yuburyo bubiri-buringaniye bwicyuma sulfide.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 byuzuyeibikoresho 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.
