From the temperature dependence of the hole concentration in lightly Al-doped 4H-SiC epilayers, a shallow acceptor with E V þ 0:2 eV, which is an Al atom ðAl Si Þ at a Si sublattice site, and an unknown deep defect with E V þ 0:35 eV are found, where E V is the valence band maximum. In unirradiated
