abstract = {Magnetotunneling spectroscopy was employed to probe the
confinement in vertical Si/Ge double-barrier resonant
tunneling diodes with regularly distributed Gequantum dots.
Their current-voltage characteristics reveal a steplike
behavior in the vicinity of zero bias, indicating resonant
tunneling of heavy-holes via three-dimensionally confined
unoccupied hole states in Gequantum dots. Assuming parabolic
confinement, we extract the strength of the confinement
potential of quantum dots.},
