• microscopy (AFM), UV–vis spectroscopy, photoluminescence (PL) and resistivity measurements in Zn1−xMgxO thin films deposited by the sol–gel spin-coating route in the composition range x = 0.00–0.40 [23]. It was found that the phase segregation manifests itself starting at a Mg content of x = 0.25. However

• –0.78 for Zn1−xMgxO thin films grown by reactive DC magnetron co-sputtering [12]. It was shown that this investigation technique is highly sensitive for the detection of embedded structural inhomogeneities, and it was found that the phase segregation occurs in the range of x = 0.35–0.65 with coexistence

Four ZnO@B samples with 20-, 40-, 60-, and 70-minute growth times, corresponding to 272, 544, 1022, and 1388 nm in thickness, were prepared (samples c-20, c-40, c-60, and c-70, respectively). For the four samples, the B2H6, DEZ, and H2O flow

• fluorescence study For the fluorescence study, nanorod thin films of ZnO and ZnO/Au were prepared on quartz glass substrate and the dye N719 was replaced with a fluorescent dye Coumarin 343 (C343, Aldrich), since N719 is nonfluorescent in nature. A 2 mM ethanolic solution of C343 dye was prepared and the

• nanorod thin films were sensitized by immersing them in the C343 solution for1 h. After sensitization, the films were washed with ethanol to remove weakly adsorbed dye molecules and dried under ambient conditions.

• force microscopy; scanning tunneling microscopy; thin films; work function; Review Introduction The chemical properties of many crystal surfaces, especially oxides, are significantly influenced by defects in the perfectly ordered structure [1][2][3][4][5]. These defects can be impurities in the surface

• instance, defects in thin films may be caused by a lattice mismatch between film and substrate. This may result in a rather frequent and sometimes regular occurrence of the defects. Defect types can be conveniently classified by the dimensionality of their spatial extension, i.e., as point, line and planar
