摘要: We have measured the low-temperature (4.2 K) current-voltage characteristics I(V) of a GaAs/(AlGa)As double-barrier resonant tunneling diode in which quantum well is intentionally 6 doped with Si donors. A peak at low voltage observed and attributed to electrons from two-dimensional free-electron-like states into fully localized bound shallow The magnetic-field dependence this fundamentally different that main resonance. show Fourier spectrum shallow-donor wave function may be deduced variation amplitude magnetic field
