Ngethuba lokuqala, iqela lamazwe ngamazwe leenzululwazi liye labonisa ukuba kunokwenzeka ukuvelisa izixa ezinokulinganiswa zombane usebenzisa i-optical diode ngokuthe ngqo kwingqele yendawo yangaphandle. Isixhobo se-infrared semiconductor esijonge esibhakabhakeni sisebenzisa umahluko wobushushu phakathi koMhlaba kunye nesithuba ukuvelisa amandla.
"Indalo enkulu ngokwayo sisixhobo se-thermodynamic," uchaza uShanhui Fan, omnye wababhali bolu phando. "Ngokwembono yefiziksi ye-optoelectronic, kukho i-symmetry entle kakhulu phakathi kwengqokelela yemitha engenayo nephumayo."
Ngokungafaniyo nokusebenzisa amandla afika eMhlabeni njengeepaneli zelanga zesintu, i-optical diode engalunganga ivumela umbane ukuba wenziwe njengoko ubushushu buphuma kumphezulu kwaye bubuyela esithubeni. Ngokukhomba isixhobo sabo kwindawo engaphandle, iqondo lobushushu elisondela ku-zero ngokupheleleyo, iqela leenzululwazi likwazile ukufumana umahluko wobushushu omkhulu ngokwaneleyo ukuze zenze amandla.
"Umthamo wamandla esikwaziyo ukuwufumana kolu vavanyo okwangoku ungaphantsi komda wethiyori," wongeza uMasashi Ono, omnye umbhali wesifundo.
Izazinzulu ziqikelela ukuba kwimo esikuyo ngoku, isixhobo sabo sinokuvelisa ii<em>nanowatt ezingama-64 kwisikwemitha ngasinye. Eli lixabiso elincinci kakhulu lamandla, kodwa kule meko ubungqina bengcamango ngokwayo bubalulekile. Ababhali bophononongo baya kukwazi ukunyusa ngakumbi isixhobo ngokuphucula iimpawu ze-quantum optoelectronic zezinto abazisebenzisayo kwidiode.
Ubalo lubonise ukuba, kuthathelwa ingqalelo iziphumo zomoya, ngokwethiyori, kunye nophuculo oluthile, isixhobo esenziwe zizazinzulu sinokuvelisa phantse i-4 W nganye kwimitha yesikwere, malunga nesigidi esiphindwe kabini kunoko kwafunyanwa ngexesha lovavanyo, kwaye ngokwaneleyo ukunika amandla izixhobo ezincinci. abafuna ukusebenza ebusuku. Xa kuthelekiswa, iiphaneli zelanga zanamhlanje zivelisa phakathi kwe-100 kunye ne-200 watts kwi-square meter nganye.
Ngelixa iziphumo zibonisa isithembiso sezixhobo ezijolise esibhakabhakeni, uShanhu Fan uphawula ukuba umgaqo ofanayo unokusetyenziswa ukuphinda kusetyenziswe ubushushu obuphuma koomatshini. Okwangoku, yena neqela lakhe bagxile ekuphuculeni ukusebenza kakuhle kwesixhobo sabo.
Uphando kupapasho lwenzululwazi lweAmerican Institute of Physics (AIP).
