Potential-inserted quantum well design for quantum cascade terahertz lasers
R. Benchamekh, J. -M. Jancu, P. Voisin
We report on a new design of terahertz quantum cascade laser based on a single, potential-inserted quantum well active region. The quantum well properties are engineered through si…
Virtual crystal description of III-V semiconductor alloys in the tight binding approach
M. O. Nestoklon, R. Benchamekh, P. Voisin
We propose a simple and effective approach to construct the empirical tight-binding parameters of ternary alloys in the virtual crystal approximation. This combines a new, compact…
Macroscopic Polarization Rotation Induced by a Single Spin
Christophe Arnold, Justin Demory, Vivien Loo +7
Solid-state spins hold many promises for quantum information processing. Entangling the polarization of a single photon to the state of a single spin would open new paradigms in qu…
Intrinsic interface states in InAs-AlSb heterostructures
F. Raouafi, R. Benchamekh, M. O. Nestoklon +2
We examine the possibility of intrinsic interface states bound to the plane of In-Sb chemical bonds at InAs/AlSb interfaces. Careful parameterization of the bulk materials in the f…
Fine structure of neutral acceptor states of isolated impurity in zinc-blende semiconductors
M. O. Nestoklon, O. Krebs, R. Benchamekh +1
The properties of neutral acceptor states in zinc-blende semiconductors are re-examined in the frame of extended-basis tight-binding model. The symmetry discrepancy be…
Tight-binding calculations of image charge effects in colloidal nanoscale platelets of CdSe
R. Benchamekh, N. A. Gippius, J. Even +6
CdSe nanoplatelets show perfectly quantized thicknesses of few monolayers. They present a situation of extreme, yet well defined quantum confinement. Due to large dielectric contra…
