RAD Journal

Silicon carbide (SiC) and nitrogen-doped silicon carbide (SiC(N)) films were deposited on p-type Si(100) substrates at various deposition conditions by means of plasma enhanced chemical vapor deposition (PECVD) technology using silane (SiH 4) methane (CH 4) and ammonium (NH 3) gas precursors.The concentration of elements in films was determined by RBS and ERD analytical method simultaneously.

3.2.2 Effective Masses and Intrinsic Carrier Density

2011-2-22 · 3. 2. 2 Effective Masses and Intrinsic Carrier Density A model for the intrinsic carrier concentration requires both the electron and the hole density-of-states masses. As aforementioned, the conduction band minimum in 4H-SiC is at the M-point in the 1BZ, thus giving rise to three equivalent conduction band minima.
