    The maximum frequency at which amplification can be obtained from quantum well oscillators is discussed. Intrinsically, the frequency limit for having negative differential resistance (NDR) can be very high, of the order of the inverse of the electron transit time. Owing to the large capacitance...

    We propose a novel quantum wire (QWR) laser structure with improved carrier capture characteristics, where the carriers are injected into a quantum well (QWL) and subsequently recombine within an embedded QWR. The corresponding electron capture rates via polar optical phonon scattering are...

    Aharonov–Bohm oscillations in a ring with a quantum well are investigated in the ballistic regime. It is shown that when trajectories with multiple circuits around the ring are taken into account, the maxima in the conductivity correspond to resonance levels of an isolated ring. The...
