  • Abstract
    Electron initiated avalanche noise measurements were performed on two Al0.3Ga0.7As pn+ diodes with p-region doping density Na=1.6×1017 cm-3 and Na=5.0×1017 cm-3 and two Al0.3Ga0.7As p+n structures with n-region doping density Nd=1.0×1017 cm-3 and Nd=4.6×1017 cm-3. The avalanche noise was found to decrease with increasing doping concentration in all structures and was found to be lower in the p+n structures than in the pn+ structures. The results are interpreted in terms of spatial coherence of the ionisation process
