Silicon carbide (SiC) thepa e le 'ngoe ea kristale e na le lekhalo le leholo la lekhalo la sehlopha (~ Si makhetlo a 3), conductivity e phahameng ea mocheso (~Si 3.3 linako kapa GaAs makhetlo a 10), tekanyo e phahameng ea ho falla ha elektronike (~ Si 2.5 linako), ho senyeha ho matla ha motlakase tšimo (~ Si 10 linako kapa GaAs 5 linako) le litšobotsi tse ling tse hlaheletseng.
Matla a Semicera a ka fana ka bareki ba boleng bo phahameng ba Conductive (Conductive), Semi-insulating (Semi-insulating), HPSI (High Purity semi-insulating) silicon carbide substrate; Ho phaella moo, re ka fana ka bareki ba nang le homogeneous le heterogeneous silicon carbide epitaxial sheets; Re ka boela ra iketsetsa leqephe la epitaxial ho latela litlhoko tse khethehileng tsa bareki, 'me ha ho na palo e fokolang ea taelo.
