Physically sound parameterization of incomplete ionization in aluminum-doped silicon

Blog Article

Incomplete ionization is an important issue when modeling silicon devices featuring aluminum-doped p+ (Al-p+) regions.Aluminum has a rather deep state in the band gap compared to boron or phosphorus, causing strong incomplete ionization.In this paper, we considerably improve our recent sepia plex parameterization [Steinkemper et al.

117, 074504 (2015)].On the one hand, we found a fundamental criterion to further reduce the number of free parameters in our fitting procedure.And on snoop snacks the other hand, we address a mistake in the original publication of the incomplete ionization formalism in Altermatt et al.
