Capacitance and conductance oscillations from electron tunneling into high energy levels of a quantum well in a p-i-n diode

S. Parolo, M. Lupatini, E. Külah +3

Two-dimensional electron and hole gases separated by a few nm from each other are produced in p-i-n diodes based upon MBE-grown GaAs/AlGaAs heterostructures. At such interlayer dis…
