Abstract :
We use a model for the ionization coefficients to calculate the frequency response characteristics and the avalanche breakdown voltage in thin layers. Notably, calculations based on the dead-space theory for the APD time response reveal that in addition to a reduction in the excess noise factor, thin layers benefit from reduced spectral fluctuations in the buildup-time limited photocurrent
