Figure 2From: Atom-to-atom interactions for atomic layer deposition of trimethylaluminum on Ga-rich GaAs(001)-4 × 6 and As-rich GaAs(001)-2 × 4 surfaces: a synchrotron radiation photoemission studyAnalysis of the core-level spectra for the clean Ga-rich GaAs(001)-4 × 6 surface. (a) As 3d state, θe = 0°, (b) As 3d state, θe = 60°, (c) Ga 3d state, θe = 0°, and (d) Ga 3d state, θe = 60°.Back to article page
