Ti (left) and VB (right) spectra for -terminated -STO(001) specimens. The numbers adjacent to the VB spectra are VBMs, as determined by extrapolating to the energy axis. Insets: Raw density of states from self-consistent GW theory for STO with a VBM arbitrarily assigned at 3.20 eV and the same after convolution with Gaussians of the indicated widths (top); typical experimental VB leading edge, showing the VBM and (bottom).Reuse & Permissions
