Abstract
O-D energy spectroscopy by means of transport and magneto-transport measurements has been carried out in double barrier resonant tunnelling heterostructures. Two models for the fabrication imposed lateral confining potential have been considered to account for the resonant lines associated with tunnelling of electrons through the O-D states of the quantum well. Preliminary measurements in a magnetic field are consistent with the values of magnetic length and undepleted conducting core radius in our structure, and indicate that up to 6 T the energy spectrum is dominated by spatial quantization. Single-charging effects in our structures are discussed.
