Figure 2b shows the temperature dependences of the electrical resistivity of polycrystalline Ag Cu alloy, single-crystal Ag, and the Ag Cu mixed crystal (See Figure S3 for the other samples). The lowered resistivity at the low temperature of 10 K reflects the fact that the doped Cu impurities did not contribute to electron. Single crystals of n-type Ca- and Ba-doped with carrier concentrations ranging from were grown and characterized as photoanodes in basic aqueous electrolyte PEC cells. The PEC properties of the crystals, including the photocurrent, photovoltage, and flatband potential in contact with NaOH(aq) were relatively independent of whether Ca or Ba was.

Pure and nitrogen-doped ZnO films are prepared on a Au() single crystal and characterized by luminescence spectroscopy in a scanning tunneling microscope. In both cases, a nm defect peak is revealed in addition to the band recombination peak at nm. The intensity of the defect peak increases when growing the film at reducing conditions or inserting nitrogen into the oxide lattice.
