Low-energy electronic states in heterostructures formed by ultranarrow layers (single or several monolayers in thickness) are studied theoretically. The host material is described within the effective mass approximation and the effect of ultranarrow layers is taken into account within the framework of the transfer matrix approach. Using the current conservation requirement and the inversion symmetry of an ultranarrow layer, the transfer matrix is evaluated through two phenomenological… 


Deep level transient spectroscopy and pseudopotential superlattice calculation for an InAs monolayer embedded in GaAs
We present deep level transient spectroscopy measurements and pseudopotential supercell calculations for InAs monolayers embedded in GaAs. The insertion of InAs MLs into GaAs generates two states in
Superlattice formed by quantum-dot sheets: Density of states and infrared absorption
Low-energy continuous states of electron in heterosrtucture with periodically placed quantum-dot sheets are studied theoretically. The Green's function of electron is governed by the Dyson equation
Optical properties of InAs/InP ultrathin quantum wells
Abstract The optical properties of ultrathin InAs impurity layers embedded in bulk InP are investigated. Our calculations are based on a tight-binding description of the electronic structure, with
Arrays of Two-Dimensional Islands Formed by Submonolayer Insertions: Growth, Properties, Devices
Ultrathin insertions of a narrow band-gap material in wide band-gap matrices represent a challenging medium in view of aspects of growth phenomena, unique optical properties, and non-trivial
Exciton resonances in ultrathin InAs/InP quantum wells
We have performed detailed optical measurements of ultrathin InAs/InP quantum wells grown by metal organic vapor phase epitaxy. Photoluminescence excitation spectra reveal the excitonic resonances
Cross-plane thermal conductivity of a PbSnSe/PbSe superlattice material
The cross-plane thermal conductivity of a PbSnSe/PbSe multi-period superlattice (SL) grown by molecular beam epitaxy is obtained from continuous wave photoluminescence (PL) measurements and finite
Single fractional monolayer (FM) CdSe/ZnSe structures have been grown by molecular beam epitaxy (MBE), employing both conventional MBE and migration-enhanced epitaxy (MEE). A precise calibration of

Study of the influence of indium segregation on the optical properties of InGaAs/GaAs quantum wells via split-operator method
In the case of quantum wells, the indium segregation leads to complex potential profiles that are hardly considered in the majority of the theoretical models. The authors demonstrated that the
Carrier lifetime measurements in short-period InAs/GaSb strained-layer superlattice structures
Minority carrier lifetime and interband absorption in midinfrared range of spectra were measured in InAs/GaSb strained-layer superlattices (SLSs) grown by molecular beam epitaxy on GaSb substrates.
