For the first time we observed a fine oscillatory structure, with the period of 36 mV, of the resonant tunneling peak in the current-voltage characteristic of a double-barrier heterostructure. We attribute it to a sequential single-phonon emission of ballistic electrons which tunneled out from the quantum well through the collector barrier. |
