Abstract

We describe a novel magnetotunneling spectroscopy technique for probing the complicated dispersion curves of hole states in the quantum well of p-type double-barrier resonant-tunneling structures. Strong mixing between light- and heavy-hole states is observed. Some of the states clearly exhibit a negative hole effective mass for motion in the plane of the quantum well.
