Vim nws cov qauv tsis tawg thiab kev ruaj ntseg ntawm cov pa roj carbon atoms, graphene yog heev muaj zog. Graphene cov cov khaubncaws sab nraud povtseg ntawm electrons sib tshooj, lub ntsiab lus tsawg dua teeb lub zog xav tau kom tau txais cov electrons dhia ntawm cov txheej txheem. Nyob rau hauv lub neej yav tom ntej, cov cuab yeej ntawd tuaj yeem ua rau heev siv tau lub hnub ci hlwb.

Ntawm no, puas yog graphene lub teeb?

Graphene tau pom thawj zaug hauv xyoo 2004, tab sis qhov ua rau muaj kev zoo siab yog tias nws cov khoom (txoj kev uas nws coj mus rau cov khoom siv) yog qhov zoo tshaj plaws thiab zoo siab. Luv luv, nws yog super-muaj zog thiab tawv, amazingly nyias, yuav luag tag nrho pob tshab, tsis tshua muaj neeg teeb , thiab ib qho amazing conductor ntawm hluav taws xob thiab cua sov.

Dab tsi ua rau graphene tshwj xeeb? Graphene tau tshwm sim los ua ib qho ntawm cov khoom zoo tshaj plaws nanomaterials vim nws tshwj xeeb ua ke ntawm superbproperties: nws yog tsis tsuas yog ib qho ntawm cov khoom siv thinnest tab sis kuj muaj zog tshaj plaws; nws ua cua sov zoo dua txhua yam khoom siv; nws yog a zoo heev conductor ntawm hluav taws xob; nws yog optically pob tshab, tseem yog li ntawd ntom

Tsuas yog li ntawd, vim li cas graphene nqus lub teeb?

Qhov pom kev sib raug zoo ntawm lub zog photon thiab tom qab ntawd tus naj npawb ntawm cov hluav taws xob ua kom zoo siab qhia tau tias graphene hloov teeb rau hauv hluav taws xob nrog high efficiency. Nws twb paub tias graphene yog muaj peev xwm nqus ib tug heev loj spectrum ntawm teeb xim.

Koj puas tuaj yeem pom los ntawm graphene?

Nws yog qhov zoo tshaj plaws pob tshab, absorbing tsuas yog 2.3 feem pua ntawm lub teeb uas tsaws rau ntawm nws, tab sis yog koj muaj ib daim ntawv dawb los muab piv rau, koj tuaj yeem pom tias nws nyob ntawd. Qhov ntawd txhais tau tias koj tuaj yeem pom ib txheej ntawm atom nrog koj qhov muag liab qab, yog lawv yog graphene . Tab sis ITO yog nkig heev, whereas graphene yog heev
