Orbital energy spectra of the c (2×2)Te structure on Ni(100) obtained by both UPS and INS show two Te‐derived orbital peaks which we interpret as arising from the nonbonding and bonding orbitals of the surface Ni; 2 Te molecular complex. These conclusions are suggested by the comparison of...
The effects of ion bombardment into MgO were investigated by measuring resulting volume changes with a cantilever beam technique and by monitoring the F band absorption induced in the uv region of the spectrum. Single crystals of MgO were bombarded near 〈100〉 with 500‐keV argon, which...
Strontium and calcium getters have possible use replacing barium as gas sorbers in color picture tubes and other electron tubes. Stable getters were made of a calcium–aluminum or strontium–aluminum alloy, which was powdered, mixed with nickel powder, and pressed into a ring‐shaped channel...
Aluminum–silicon contacts are extensively used in integrated circuits. Contact resistance of Al–Si contacts is sensitive to silicon surface preparation, vacuum ambience of aluminum film deposition, and contact sintering conditions. Controlled contamination experiments have been carried out...
Evaporation of Al–Cu alloy is accomplished by codeposition from a crucible heated by rf induction. This paper presents a discussion of the mechanisms affecting the amount of copper deposited on the substrates. Knowledge of this is used to structure a loading scheme to insure long crucible life...
The role the electronic and geometric structures of the metal surface play in electrochemical surface reactions remains as yet an unknown factor. In order to investigate these surface contributions to electrochemical reactions, a low‐energy‐electron diffraction (LEED) and an Auger electron...
The structure and composition of a test solar black, gold black, has been investigated in order to more fully understand the particulate nature of good solar‐energy absorbers. Inert‐gas‐evaporated gold‐black films showed significant dependence of film‐particle size on inert‐gas...
In this review article we discuss the role of heterostructures in integrated optics. We consider, in sequence, the role of heterostructure waveguides, lasers, light couplers, modulators, and detectors, and describe the progress made to date in integrating these into a thin‐film monolithic...
