Electronic structure and optical properties of serpentine superlattice quantum-wire arrays.
نویسنده
چکیده
The subband structure and band-to-band optical matrix elements are computed for serpentine superlattice quantum-wire arrays. The subband dispersion and bandwidths are examined as a function of the curvature of the confining barriers and of the barrier height separating the wires. The optical matrix elements show a strong polarization dependence, even when the coupling between wires in the array is sufticiently strong that the states are not quasi-one-dimensional.

متن کاملConductance in quantum wires by three quantum dots arrays
A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...
