Abstract :
We report measurements of electron initiated avalanche noise at room temperature in a range of InP p+-i-n+ diodes with i-region widths, M ranging from 2.40 μm to 0.24 μm. A significant reduction in excess noise is observed with decreasing w at constant multiplication. We also report electron initiated photomultiplication and breakdown voltage of InP p+-i-n+ diodes with nominal i-region widths of 0.30 μm and 0.50 μm at temperatures ranging from 20 K to 300 K. Improved temperature stability is observed as the avalanche region width is reduced
