Abstract

A two-dimensional resistor network was used to simulate the conductivity and Hall effect in an inhomogeneous inversion layer. Two types of inhomogeneities were considered: Poisson-distributed conductivity fluctuations, and correlated inhomogeneities. forming elongated inclusions. The conductivity was found to be rather insensitive to the type of fluctuations chosen, but the Hall carrier concentration is strongly model-sensitive. The computer simulations are compared with experimental data and with the results of the effective medium theory.

    We think that one of the possible candidates for the observed non-uniformities may be associated with C-related defects, which were investigated in previous studies on SiO2/4H-SiC interfaces [16,19]. We note that it is likely that the observed charge non-uniformities at the SiO2/SiC interfaces influence the carrier transport characteristics of SiC-MOSFETs because it is known that the non-uniformities of the interfacial charges degrade the carrier transport in the inversion layer of Si-MOS transistors [20–22]. To investigate the spatial resolution of tr-SNDM, distribution of trap occupation function at the SiO2/SiC interface during the tr-SNDM measurements were calculated using a TCAD simulator (ATLAS).
