摘要：

Avalanche multiplication and excess noise arising from both electron and hole injection have been measured on a series of In0.52Al0.48As p(+)-i-n(+) and n(+)-i-p(+) diodes with nominal avalanche region widths between 0.1 and 2.5 mu m. With pure electron injection, low excess noise was measured at values corresponding to effective kappa = ss/alpha between 0.15 and 0.25 for all widths. Enabled ionization coefficients were deduced using a non-local ionization model utilizing recurrence equation techniques covering an electric field range from approximately 200 kV/cm to 1 MV/cm.
