XEOL photocurrent measured behind the bare substrate at 60° incidence. The measurements were made at room temperature, except for MAO, STO and Cr:STO which were measured at 100 K. The normal flux conditions used for almost all substrates was with a front-end slit opening of 0.5 mm × 0.5 mm. For DSO and NGO the horizontal front-end slit was further open to 1.0 mm and 1.7 mm, respectively. |
