Digital AlxGa1-xAs alloys consisting of a repeated structure of alternating layers of AlAs and GaAs were grown between layers of GaAs. Lateral oxidation characteristics of these digital AlxGa1-xAs (x≫0.8) alloys were determined. Decreasing aluminum compositions resulted in slower oxidation rates, similar to true AlxGa1-xAs alloys. Further investigations of the oxidation characteristics of a digital Al0.98Ga0.02As alloy indicate that shorter periods ...

Low contact resistance to digital alloys of n-type AlGaN/AlN with high average Al concentration is described. Low-energy electron diffraction was used to evaluate surface precleaning with HCl and buffered HF. The contact metallization consisting of a stack of Ti/Al/Ti/Au, 20/100/45/60 nm in thickness, was e-beam deposited and etch-patterned. The lowest specific contact resistance of 5.6×10-5 Ω*cm2 was obtained after annealing ...

We present the first lattice-matched InGaAs quantum well lasers with barriers and waveguide grown using a digital alloy MBE technique. By rapidly switching the ternaries of AlInAs and InGaAs, the digital alloy process permits the growth of any quaternary AlGaInAs composition
Saito, K. Magnetics, IEEE Transactions on, 1990
Excellent performance of laminated Fe-Si-Al alloy film heads is demonstrated in applications to high-definition VCR and to digital recording. It is emphasized that these results are derived not only from the ring-shaped core geometry but also from the isotropic behavior in the magnetic properties of the sputtered Fe-Si-Al alloy films. The experimental results on the isotropic magnetic behavior are summarized. ...

Local structure and effective chemical valency of Mn atoms in Mn/GaAs digital alloys have been investigated using the x-ray absorption fine structure techniques. The samples were prepared by molecular-beam epitaxy with different thickness of GaAs layers separating the nominal Mn monolayers. Lattice constants of the digital alloys are found by x-ray diffraction to increase linearly in a very narrow range ...
