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.
