The surface As/Ga atoms 3d core-level spectra of the atomically clean GaAs(1 1 1)A-2 × 2, GaAs(0 0 1)-2 × 4, and GaAs(0 0 1)-4 × 6 surfaces were firstly presented using high-resolution synchrotron radiation photoemission as a probe. The technique

During the initial stage of atomic layer deposition, the exposure of a GaAs(111)A-2×2 surface to trimethylaluminum (TMA) leads to occupying a Ga-vacancy site on the surface by a chemisorbed As-bonded aluminum with the loss of all methyl ligands. The

The electronic structure of single-crystal (In)GaAs deposited with tri-methylaluminum (TMA) and water via atomic layer deposition (ALD) is presented with high-resolution synchrotron radiation core-level photoemission and capacitance-voltage (CV) char

In atomic-layer deposition (ALD), organoaluminum as trimethyl-aluminum (TMA) on a freshly molecular beam epitaxy grown In0.20Ga0.80As(001)-4 × 2 surface has three forms: Al bonding with 1, 2, and 3 methyl groups. The ALD method of using one pulse (0

Guided by the known reconstruction of the GaAs(111)A-2×2 surface, the Ga 3d electron surface atom core-level shifts was found to be 0.30±0.01 eV and that of the surface As atoms with three-fold Ga coordination -0.25±0.01 eV. The four-fold coordina

Guided by the criteria of strong oxygen affinity and strong tendency toward surface segregation over Nb, artificial tunnel barriers of thin Mg(10-65 A), and Y(4-30 A) overlayers on Nb were investigated. Very high-quality tunnel junctions of the types

The bathyphotometer described is a combination of a light-meter employing a photomultiplier tube and a depthmeter employing a bourdon tube. The spectral sensitivity of the instrument extends approximately from 320 mμ to 650 mμ with a maximum at 480
