Electrical and optical properties of WO3 thin films

Improvement of thermoelectric properties of WO3 ceramics by ZnO addition

“…Previous studies [31][32][33] clarified that the electrical properties involving electrical conductivity and thermo-power could not be explained by a simple defects model except under strongly reduced conditions. The electrical conductivity of semiconductors depends on their carrier concentration (n) and mobility ( ) in the following way [34]:…”

“…[38], and the electrical conductivity is improved. Besides, the mobility of the carriers is strongly influenced by the disorder present in the materials and by impurity doping [34]. The conductivity of WO 3 was reported to decrease due to an increasing volume of the grain boundaries, which contributes to more trapping and scattering of free charge carriers.…”

Fabrication and characterization of nanostructural WS2/WO3 binary compound semiconductors prepared by the sulfurization of sprayed thin films

“…It is used for the construction of smart windows [2], mirrors, optical shutters and display devices [3], etc. Up to now, several techniques for the growth of WO 3 thin films have been reported: thermal evaporation [4], flash evaporation [5], electron beam [6], spray pyrolysis [7], sputtering [8], and sol-gel coating [9].…”

An Attempt to Optimize ZnO-Like TCO Nanolayered Compound Thickness in Terms of a BPES-Related Physical Parameters Pondering

“…Recently, several nanolayered transparent conducting oxides TCO have been investigated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] for their interesting optical, mechanical, and electrical performance and besides all their high optical transparence in the visible domain. Commonly, these oxides could be synthesized using several methods [21,22] like reactive evaporation, electron beam evaporation (EBE), pulsed laser deposition (PLD), chemical vapor deposition (CVD), sol-gel coating, and chemical spray pyrolysis.…”
