The structure of InAs(0 0 1)-(2×4) surfaces equilibrated under typical MBE conditions is studied by scanning tunneling microscopy (STM). Depending on the magnitude of the As flux, typical surfaces are found to contain a mixture of α2(2×4) and β2(

The stability of different surface reconstructions on InAs~001! is investigated theoretically and experimentally. Density-functional theory calculations predict four different surface reconstructions to be stable at different chemical potentials. The

We adapt the level set method to simulate the growth of thin films described by the motion of island boundaries. This island dynamics model involves a continuum in the lateral directions, but retains atomic scale discreteness in the growth direction.

We introduce a model for epitaxial phenomena based on the motion of island boundaries, which is described by the level-set method. Our model treats the growing film as a continuum in the lateral direction, but retains atomistic discreteness in the gr

We present experimental data for the morphological evolution of InAs buffer layers which are interpreted using continuum equations of motion and kinetic Monte Carlo simulations. Our analysis reveals the presence of an instability even as an initially

Manipulation of electron spin is a critical component of many proposed semiconductor spintronic devices. One promising approach utilizes the Rashba effect by which an applied electric field can be used to reduce the spin lifetime or rotate spin orien

Photoemission oscillations (PEO) are measured during the growth of InAs/AlSb/GaSb resonant tunneling diodes on (0 0 1) GaAs and (0 0 1) InAs substrates. PEO of the GaSb well are unresolved for growth on GaAs substrates but clearly observable for grow

Thermally pre-cracked diethylzinc and diethylselenide were used for the metalorganic molecular beam epitaxial growth of (001) ZnSe films on (001) GaAs substrates. The growth kinetics of (001) ZnSe was studied by measuring the growth rate as a functio

In this paper “laminar-flow” and “plug-flow” models are presented for engineering photo-assisted chemical vapor deposition reactors. It is shown that the growth rate depends directly on the photodissociation rate, which in turn is proportiona

A reaction mechanism is presented for photo-assisted organometallic vapor-phase epitaxy (OMVPE) of cadmium telluride. Dimethylcadmium and dimethyltellurium are photodissociated in the gas into Cd and Te atoms and methyl radicals by 248 nm photons fro
