We report the realization of quasi-three-dimensional electron systems in selectively-doped wide parabolic quantum wells, focusing on a novel superlattice which contains a high-mobility ( ≈ 1.1×10 5 cm 2 /V⋯s at 4 K) degenerate electron system. T

An investigation was made of Pt–Ir silicide films on (100)Si prepared by deposition of submonolayer thickness of Pt followed by 20–30 A of Ir. Submonolayer coverages of Pt induce a crystalline texture approaching an epitaxial relationship between

We have investigated the effect of substrate temperature, T S , during growth by molecular beam epitaxy on the migration of Si atoms in δ- (or planar) doped GaAs and Al 0.25 Ga 0.75 As. Determinations of the extent of Si migration were made through

The effect of electron stimulated desorption (ESD) during secondary ion mass spectrometry (SIMS) from BF+2 implanted SiO2 was investigated. We have quantitatively illustrated that the F+ depth profile is directly related to electron current density w

We have investigated the migration of Si in delta (δ)‐doped GaAs and Al0.25Ga0.75As structures using secondary ion mass spectrometry. The results demonstrate that: (1) the extent of Si migration strongly depends on the substrate temperature Ts; (2

In this paper, we describe an investigation of structure and motion in fluidic microsystems using unique x-ray imaging, visualization and analysis techniques. By way of illustration, we have applied x-ray microtomography in an investigation of the in

The epitaxial growth of an adsorbed layer of NH 3 on top of chemisorbed CO on Ni(111) and Ni(110) surfaces was studied using ESDIAD. A strong interaction yielding an activation energy for NH 3 desorption of ∼12 kcal/mol was observed. This interacti

Temperature programmed desorption measurements for H2/Ni(111) yield two desorption states, β1(T=290 K) and β2(T=370 K) for saturation H coverage. The two states are found to have distinctly different angular distributions. β2‐H2 desorption is st

It is shown that alkali adatoms coadsorbed in the presence of adsorbed hydrogen on Ni(111) can cause a large increase in the cross section for H+ emission during electron stimulated desorption. This phenomenon was investigated using the digital ESDIA
