Abstract

Hole and mixed multiplication characteristics are obtained on thick 4H-SiC avalanche photodiodes (APDs) with nominal avalanche widths between 2.7 and 6 [micro]m. Ionization coefficients are parameterized over the electric field range from 0.9 to 5 MV/cm, which have helped in the accurate prediction of the multiplication and breakdown characteristics of 4H-SiC.
