Paper Abstract

Pseudomorphic Al 35Ga 65As/In 1Ga 9As resonant tunneling diodes fabricated with asymmetric spacer layers adjaceht to the tunnel barrier were characterized via magneto-transport measurements. Novel tunneling effects (ground vs excited state tunneling) were observed in the current-voltage characteristics of these devices which depend upon the bias direction. Shubnikov-de Haas oscillations obtained at high magnetic fields show a strong asymmetry with bias direction and give evidence of silicon dopant out diffusion during molecular beam epitaxy.
