Band Structure and Magneto- Transport Properties in II-IV Nanostructures Semiconductors - Application to Infrared Detector Superlattices

“…1 whereas, in intrinsic regime, α ∼T -3/2 and R H T 3/2 indicates a measured gap E g ≈ 190 meV in agreement with calculated E g ( ,300 K) = 178 meV. Using the value of the gaps ε 1 and ε 2 at different temperatures between 4.2 K and 300 K (Weiler, 1981) and taking P temperature independent, this is supported by the fact that from Eq. (4) P ≈ ε i (T)/m*(T) ≈ cte, we get the temperature dependence of the band gap E g , in the center of the first Brillouin zone in Fig.…”

Spin-Flip Effect in Narrow-Gap Semiconductor Quantum Wells

“…[8] Weiler makes an extensive comparison between the number of different k Á p models and to some inconsistent Bloch basis set found in the literature. An adequate, realistic and very consistent bulk band structure model for narrow-gap semiconductors in a magnetic field is the Kane-Weiler 8 Â 8 k Á p Hamiltonian that we will extend to calculate the magneto-electronic structure in quantum well heterostructures of narrowgap semiconductors.…”

“…As we can expect, important changes on the optical and transport properties of the narrow-gap G c 6 states, as a direct result of the stronger conduction-valence band coupling, have been reported (see Refs. [8,11]). …”

“…[5,6]. In the present paper we will discuss the main theoretical approaches to the Kane-Weiler Hamiltonian extended to narrow-gap QWs in an external magnetic field including the strain effects [7,8]. We introduce a proper basis set for the Landau ladders [9][10][11] within the full 8 Â 8 k Á p model as derived from the inherent symmetry present in this Hamiltonian model.…”

Effective g ‐factor control in II‐VI quantum dots: morphological effects

“…ii) The Landé g-factor for electrons. We calculate the magneto-electronic structure using a version of Weiler-Kane k · p method [5,6,7] to describe, in a precise manner, the QD size and shape effects and their connections with the interband couplings, which define the electronic structure of a QD in presence of an external magnetic field.…”
