Effect of the AgO content on the surface morphology and electrical properties of SnO2 thin films prepared by PLD technique

الملخص EN

Tin dioxide doped silver oxide thin films with different x content (0, 0.03, 0.05, 0.07) have been prepared by pulse laser deposition technique (PLD) at room temperatures (RT).

The effect of doping concentration on the structural and electrical properties of the films were studied.

Atomic Force Measurement (AFM) measurements found that the average value of grain size for all films at RT decrease with increasing of AgO content.

While an average roughness values increase with increasing x content.

The electrical properties of these films were studied with different x content.

The D.C conductivity for all films increases with increasing x content.

Also, it found that activation energies decrease with increasing of AgO content for all films.

Hall measurements confirmed that all the intrinsic films are n-type charge carriers.

The variation of carriers concentration increase with increasing x content.

Hall mobility decreasing with increasing x content for all films.

Also the variation of Drift velocity, carrier life time and free mean path decrease with increasing of x content
