Sei bepa regirafiti richifambisa magetsi?

Nekuti graphite ine machaji anofamba-famba, machaji acho anofamba zvakasununguka mushure mekushandiswa kwemagetsi kuti agadzire magetsi, saka anogona kutungamira magetsi. Chikonzero chaicho chinoita kuti graphite itungamirire magetsi ndechekuti maatomu matanhatu ekabhoni anogovana maerekitironi matanhatu kuti agadzire chisungo chikuru che∏66 nemaerekitironi matanhatu nenzvimbo nhanhatu. Muring yekabhoni yechikamu chimwe chete chegraphite, maring ese ane nhengo nhanhatu anoumba sisitimu yakabatana ye∏-∏. Nemamwe mashoko, muring yekabhoni yechikamu chimwe chete chegraphite, maatomu ese ekabhoni anoumba chisungo chikuru che∏, uye maerekitironi ese ari muchikamu ichi chikuru che∏ anogona kuyerera zvakasununguka muchikamu, ndicho chikonzero nei bepa regirafu richigona kutungamira magetsi.

Graphite chimiro che lamellar, uye kune maerekitironi asina kusungirirwa pakati pezvikamu. Mushure mekuiswa kwemagetsi, anogona kufamba akananga. Zvinhu zvese zvinoshandisa magetsi, ingori nyaya ye resistivity. Maumbirwo e graphite anoratidza kuti ine resistivity diki pakati pezvinhu zvekabhoni.

Pfungwa yekufambisa yepepa regraphite:

Kabhoni iatomu ine tetravalent. Kune rumwe rutivi, kungofanana nemaatomu esimbi, maerekitironi ekunze anorasika zviri nyore. Kabhoni ine maerekitironi mashoma ekunze. Yakafanana zvikuru nesimbi, saka ine magetsi anofambisa magetsi. , maerekitironi akasununguka anoenderana uye maburi achagadzirwa. Pamwe chete nemaerekitironi ekunze ayo kabhoni inogona kurasikirwa zviri nyore, pasi pechiito chemusiyano unogona kuitika, pachava nekufamba uye kuzadza maburi. Gadzira kuyerera kwemaerekitironi. Iyi ndiyo nheyo yemasemiconductors.
