Abstract

We have used a model based on local density of states functions to calculate the surface electronic structure for both perfect SrTiO3(100) surfaces and for surfaces containing O-vacancy defects. The calculations are in excellent agreement with ultraviolet photoemission spectra for both types of surfaces. A magnetic layer with μ ≈ 2.3 μB per surface unit cell is predicted for the O-vacancy SrTiO3(100) surface. © 1978.
