Structural and optical characteristics of spin-coated ZnO thin films

Structural Characteristics and Optical Properties of Thermally Oxidized Zinc Films

“…The obtained values of the band-gap width, E g0 , ranged between 3.17 eV and 3.19 eV. These values are in good agreement with those reported for bulk ZnO samples [2,7,33,34].…”

Correlated effects of preparation parameters and thickness on morphology and optical properties of ZnO very thin films

“…In addition, both synthesis temperatures and concentration seem to accelerate this observed evolution with number of deposition cycles, as a consequence of a faster growth and faster increasing thickness when these preparation parameters increase. Although thickness is known to have effects on crystal orientation and grains size [11][12][13][14][15][16][17][18][19][20][21][22][23], the evolution observed in the present work however involves thinner layers and seems to be different than those reported. The low thickness of the considered layers could be responsible for particular mechanisms of grains coarsening.…”

“…Thickness can have a great influence on structural, morphological, optical and electrical properties of layers obtained by magnetron sputtering [7][8][9][10], pulsed laser deposition, or solgel. In this particular case of sol-gel synthesis, thickness can especially be controlled by varying the number of deposition cycles, offering a wide range of different granular morphologies and correlated properties [11][12][13][14][15][16][17][18][19][20][21][22][23].…”

Structural and optical properties of ZnO thin films prepared by spin coating method

“…The ZnO material is produced by several techniques such as chemical vapor deposition [2], [3], magnetron sputtering [4], [5], spray pyrolysis [6], and the sol-gel method [7], [8], [9]. In this work, we are interested in a spin coating technique because it is particularly adapted to fabricate ZnO films in a simple, low cost and highly controlled way.…”
