Deposition of indium tin oxide films by laser ablation: Processing and characterization

1998

Abstract In this work an indium tin oxide thin film fabrication technique based on pulsed laser deposition is described and the electrical, optical and mechanical properties of the deposited films are reported. Deposition of high quality films on cold substrates was proved. The third harmonic (355 nm) of an Nd:YAG laser was employed to photoablade the indium tin oxide target.

A Simple Apparatus for the Determination of the Optical Constants and the Thickness of Absorbing Thin Films

2001

We report on a simple and inexpensive apparatus useful for measuring the optical constants n, k and the thickness of weakly absorbing thin films. The measurement is based on an accurate determination of the reflectance and transmittance of a specimen illuminated by a laser beam. The laser beam is incident on a transparent substrate coated with the film to be evaluated, with an angle of incidence equal to the Brewster angle for the substrate, and its polarization can be switched between the p and s states. If the thickness is known to be within a presumptive range, measurements of the p and s reflectance and transmittance allow a calculation of the optical constants n, k and the thickness of…
