Abstract
Resonant tunneling is observed in double barrier resonant tunneling di odes (RTDs) with semi-metallic ErAs quantum wells. Magnetic field depe ndence distinguishes two different resonant channels. From the thickne ss dependence of the voltage for resonant tunneling the dispersion of the channels is found to be hole-like. The dispersion agrees well with the theory that identifies the two channels with m(j) = +/- 1/2 and m (j) = +/- 3/2, hole states.
