Abstract

Tunnelling through highly localised impurity states in the quantum well of a resonant tunnelling diode allows us to study the properties of the two-dimensional electron gas formed at the emitter barrier of the device. In high magnetic fields, the electrons form quantum dots in the disordered potential due to the unscreened donors in the depleted collector contact.
