چکیده

The GaAs short-period superlattices have been grown for the first time by the metal-organic hydride epitaxy method using Se and C for quasi-doping. Photoluminescence spectra measured at 4.2 K display well-distinguished peaks, which coincide with transitions between quantizied levels of electrons and holes in the potential relief quantum wells. To describe observed phenomena in quasi-doped superlattices a theory is developed with taking into account existing tails of the density of states.

Luminescence from Miniband States in Heavily Doped Superlattices

We have studied doped superlattices of GaAs/AlGaAs composition. When the doping atoms are introduced into the barriers surrounding the superlattice, as well as to the inner ones, but with half of the concentration, the photoluminescence due to interband transitions from extended superlattice states is detected. This is demonstrated by a study of the sample’s photoluminescence in a magnetic fiel...

lnAs/Ga1 _x lnxSb strained-layer superlattices grown by molecular-beam epitaxy

We report the successful growth oflnAs/Ga 1 _ x Inx Sb strained-layer superlattices by molecularbeam epitaxy. The superlattices are grown on thick, strain-relaxed InAs or GaSb buffer layers on ( 100)-oriented GaAs substrates. A short-period, heavily strained superlattice at the GaAs interface is found to improve the structural quality of the buffer layer. Arsenic incorporation in nominally pure...

Temperature dependence of photoluminescence of an n-i-p-i GaAs superlattice

Since the concept of doping superlattice was proposed by Esak and Tsu, the electronic properties of it were intensively investigated both theoretically and experimentally. Doping superlattices are structures which contain alternatively n-type and p-type doped regions of one semiconductor material and have a number of unique properties, such as tunable electronic structures, indirect band gap in...

I Porosity superlattices : a new class of Si I 1 heterostructures

Porosity superlattices have been investigated by transmission electron microscopy, photoluminescence and reflectance spectroscopy. The superlattices were formed on p-type doped Si using two different techniques. Firstly, for homogeneously doped substrates we have periodically varied the formation current density and thereby t h e porosity. Secondly, the current density was kept constant while e...

Theoretical luminescence spectra in p-type superlattices based on InGaAsN

In this work, we present a theoretical photoluminescence (PL) for p-doped GaAs/InGaAsN nanostructures arrays. We apply a self-consistent k→p→ method in the framework of the effective mass theory. Solving a full 8 × 8 Kane's Hamiltonian, generalized to treat different materials in conjunction with the Poisson equation, we calculate the optical properties of these systems. The trends in the calcu...
