Abstract

Polytypic 3C quantum wells (double Shockley stacking faults) are spontaneously generated during thermal processing of moderately doped 4H-SiC epilayers grown on substrates with heavy n-type doping above ∼3×1019 cm-3. They intersect the wafer surface as straight lines, due to the 8° misorientation of the wafer from the c-axis. We describe observations of electric fields and charge associated with these intersections using electrostatic force microscopy (EFM) and scanning Kelvin probe microscopy (SKPM). The results are compared to two-dimensional electrostatic simulations.
