A new one-dimensional quantum well structure is proposed. The structure is created by converting one side of the potential barrier of an asymmetric quantum well into a periodically indented potential. Both the electron and hole states are confined in the one-dimensional channel adjacent to the indented region of the side potential barrier, making it possible to achieve enhanced exciton binding energies and oscillator strengths for optical properties.

    The scheme of a laser which can operate in the far-infrared range (λ ∼ 150 µm) is suggested. In order to attain the inversion of the subband population it was suggested that electron transport in three tunnel-coupled quantum wells in a strong electric field, which lies in the plane of...

    The electronic structure and the linear response to an external electric field of simple metal wires with a quantum-size cross-section have been studied within the density-functional theory and the "jellium" model. It is found that an increase in the wire radius leads to a nonmonotonic change in...
