Equilibrium properties of electrons in double-heterojunction AlGaAs/GaAs/AlGaAs structures are investigated theoretically, using a fully self-consistent numerical method. The transition from single to bilayer electron systems is discussed for structures with varying distance between interfaces as a function of the in-plane magnetic field strength. A phenomenon of separability of the energy dispersion curves in parts corresponding to electrons in either the first or the second layer is analysed… 
The density of states and the electron concentration of a double-heterojunction system subjected to an in-plane magnetic field
We calculate the electronic states of AlxGa1-xAs/GaAs/AlxGa1-xAs double heterojunctions subjected to a magnetic field parallel to the quasi-two-dimensional electron gas layer. We study the energy
Orbital effect, subband depopulation, and conductance fluctuations in ballistic quantum dots under a tilted magnetic field.
Using two-dimensional electron gases (2DEGs) confined to wide and narrow quantum wells, we study the magnetoconductance of ballistic quantum dots as a function of the well width and the tilt angle of
Composite fermion liquid to Wigner solid transition in the lowest Landau level of zinc oxide
The authors' observations indicate the direct competition between a Composite fermion liquid and a Wigner solid formed either by electrons or composite fermions, in a zinc oxide heterostructure.
Parallel field-induced universal conductance fluctuations in open quantum dots
Open quantum dots (OQDs) are now commonly used as an experimental tool for the investigation of a particular regime of quantum transport where the electron dynamics is both ballistic and coherent. In
Cyclotron resonance study of the two-dimensional electron layers and double layers in tilted magnetic fields
The far-infrared absorption in two-dimensional electron layers subject to magnetic field of general orientation was studied theoretically. The Kubo formula is employed to derive diagonal components
Non-monotonic behaviour of the energy levels of quantum wells with a large mass mismatch in the presence of an in-plane magnetic field
We present a theoretical study of the electron states in a quantum well with finite barrier height in a magnetic field applied parallel to the quantum well. For large electron mass mismatch between
LETTER TO THE EDITOR: Looking for the maximum low-temperature conductivity in selectively doped ? double heterojunctions
We use self-consistent numerical calculations to study the sheet electron concentration and the mobility as functions of the doping concentration, the spacer thickness, the well width and the Al mole


A systematic study of electronic states in n-AlxGa1-xAs/GaAs/n-AlxGa1-xAs selectively doped double-heterojunction structures
The electron concentration, the wavefunctions and the energy levels of a n-AlxGa1-xAs/GaAs/n-AlxGa1-xAs double heterojunction are evaluated by solving Schrodinger and Poisson equations

In-plane low-temperature transport properties are proposed in doped thin double quantum wells in an in-plane magnetic field with density of states diverges at a saddle point and the correlation between the recently observed tunneling and the in-planes is discussed.
In-plane magnetic-field-induced anisotropy of 2D Fermi contours and the field-dependent cyclotron mass
The electronic structure of a 2D gas subjected to a tilted magnetic field, with a strong component parallel to the GaAs/AlGaAs interface and a weak component oriented perpendicularly, is studied

The study of the electronic structure of two parallel two-dimensional layer systems in tilted magnetic fields finds that a crossover occurs as a function of field strength between a region at weak perpendicular fields where semiclassical approximations are accurate and a region where the probability of magnetic breakdown becomes large and semiclassicals fail.
Electronic structure of semiconductors with doping superlattices
The dynamically two-dimensional electronic subband structure and the effective energy gap are tunable quantities in semiconductors with a doping superlattice. We present self-consistent calculations
