We have provided direct evidence of the enhanced effectiveness of stabilizing agents due to thin surface oxide films, ca. 15-25 A, on n-Si photoelectrode. Rotating ring disc electrode and ellipsometric experiments are combined to show the stabilization efficiency of potassium ferrocyanide improves with oxide thickness. A band model describing the observed effect is given.

The adsorption of bismuth on Si(ll0) surfaces has been studied by means of quadrupole mass spectrometry (QMS), LEED and AES. The existence of three main adsorption states (the first, second and third phases) were observed. Two of them (the first and second phases) are two-dimensional phases and the other (the third phase) is a three-dimensional phase. After the completion of the first phase at a high substrate temperature, the LEED pattern showed a clear Si(ll0) 2 X 3 structure. A shift of the saturation coverage of the two-dimensional phase with the change of the deposition condition was also observed.

Using a simple model we predict that pronounced angular resonances will be observed in the emission from a dipole located near a silver surface having a sinusoidal profile. The result is relevant to Raman and fluorescence spectroscopy.
