Ishishini le-semiconductor lishishini elikhulayo lesayensi netekhnoloji, eliye latsala ingqalelo enkulu kwiminyaka yakutshanje, iinkampani ezininzi ziye zaqala ukungena kwishishini le-semiconductor, kwaye i-graphite iye yaba yenye yezinto ezibalulekileyo ekuphuhlisweni kweshishini le-semiconductor. Ii-semiconductors kufuneka zisebenzise i-electrical conductivity ye-graphite, kuba okukhona umxholo wekhabhoni we-graphite uphezulu, kokukhona i-electrical conductivity ingcono, ngokubanzi kufuneka ziqwalasele izalathisi zezi: ubungakanani bamasuntswana, ukumelana nobushushu, ubunyulu.
Ubungakanani bengqolowa buhambelana namanani ahlukeneyo e-mesh, kwaye iinkcukacha zichazwa ngamanani e-mesh. Inombolo ye-mesh linani leemingxuma, oko kukuthi, inani leemingxuma nge-intshi yesikwere. Ngokubanzi, inani le-mesh * i-aperture (micron) = 15000. Okukhona inani le-mesh le-graphite eqhubayo lilikhulu, kokukhona ubungakanani be-particle buncinci, kokukhona ukusebenza kwe-lubrication kungcono, kunokusetyenziswa kwicandelo lokuvelisa izinto zokuthambisa. Ubungakanani be-particle obusetyenziswa kwishishini le-semiconductor kufuneka bube buhle kakhulu, kuba kulula ukufikelela ngokuchanekileyo kokucubungula, amandla aphezulu okuxinzelela, kunye nokulahleka okuncinci, ngakumbi kwiimolds ezisilayo, ezifuna ukuchaneka okuphezulu kokucubungula.
Ukusasazwa kobungakanani bamasuntswana, okufana: i-20 mesh, i-40 mesh, i-80 mesh, i-100 mesh, i-200 mesh, i-320 mesh, i-500 mesh, i-800 mesh, i-1200 mesh, i-2000 mesh, i-3000 mesh, i-5000 mesh, i-8000 mesh, i-12500 mesh, eyona incinci kakhulu ingaba yi-15,000 mesh.
Iimveliso ezininzi kwishishini le-semiconductor kufuneka zifudunyezwe rhoqo, ukuze kwandiswe ubomi benkonzo yesixhobo, nto leyo efuna i-graphite eqhubayo ukuze ibe nezi mpawu zilandelayo: ukuthembeka okugqwesileyo kunye nokumelana nefuthe lobushushu obuphezulu.
Iimfuneko zokuveliswa kwegrafiti kushishino lwe-semiconductor zezi: okukhona ubunyulu buphezulu, kokukhona kungcono, ingakumbi izixhobo zegrafiti ezichukumisa phakathi kwezi zimbini, ukuba ziqulathe ukungcola okuninzi, ziya kungcolisa izinto ze-semiconductor. Ke ngoko, kufuneka silawule ngokungqongqo ubunyulu begrafiti eqhubayo, kwaye kufuneka sikwaphathe ngegrafiti yobushushu obuphezulu ukuze kuncitshiswe inqanaba elingwevu.
