Ntxiv nrog rau nws cov khoom hluav taws xob, graphite semiconductor kuj muaj cov khoom siv thermal zoo. Cov khoom siv Optoelectronic feem ntau ua kom muaj cua sov thaum lub sijhawm ua haujlwm, thiab kev ua kom sov kom zoo yog qhov tseem ceeb los tswj lawv cov kev ua tau zoo thiab kev ntseeg tau. Lub siab thermal conductivity ntawm graphite pab nyob rau hauv dissipating lub tshav kub generated, tiv thaiv overheating thiab tej kev puas tsuaj rau lub cuab yeej.
Thaum nws los txog rau kev tsim khoom, graphite semiconductor muaj qee qhov zoo. Nws tuaj yeem tsim los ntawm kev siv yooj yim thiab tus nqi - txoj hauv kev zoo piv rau qee cov khoom siv semiconductor. Chemical vapor deposition (CVD) yog ib qho txheej txheem uas feem ntau siv rau kev loj hlob graphite txheej, uas tuaj yeem tswj tau meej los tsim cov yeeb yaj kiab siab - zoo graphite nrog cov thickness thiab cov khoom xav tau. Qhov yooj yim ntawm kev tsim khoom no tuaj yeem ua rau txo qis cov nqi tsim khoom thiab cov txiaj ntsig siab dua hauv kev tsim cov khoom siv optoelectronic.
