This work simulated the avalanche characteristics of 4H- and 6H-SiC avalanche photodiodes (APDs) at 0.1 µm, 0.2 µm and 0.3 µm avalanche widths. A Monte Carlo model with random ionization path length techniques is developed to simulate mean multiplication gain and excess noise factor in thin SiC APDs. Mean multiplication gain, breakdown voltage and excess noise factor are simulated based on the electric field dependent impact ionization coefficients with the inclusion of dead space effect. Our results show that hole-initiated impact ionization gives high multiplication gain with low excess noise factor in both devices. We observed that dead space effect is more pronounce in thin structure since it covers a significant portion of the avalanche region. In thick device structure, a high breakdown voltage is observed. A comparison between these two polytypes shows that 4H-SiC provides high multiplication gain with low excess noise factor than 6H-SiC.

Abstract This project aims to develop a graphical user interface (GUI) for MATLAB programs written by J. S. Marsland as part of his research on the excess noise factor in avalanche photodiodes (APDs). The GUI will be developed using the GUIDE package supplied with MATLAB. The GUI will then be used to compare this research with other works—for example, the Monte Carlo calculations performed by the research group at the French Aerospace Laboratory (ONERA). A comparison with other works will require the digitisation of graphs, some of which have been published in academic journals.
