Abstract

We compare the sensitivity of measuring the reflectivity and angular Goos-Hänchen Θ_GH shift to determine CuO film thickness on a Cu substrate. Calculation of the response of the detectors used in reflectivity and beamshift measurements showed the capability of both techniques in measuring film thickness less than 8 nm. Our results showed that the response of a photodiode in reflectivity measurements is three orders of magnitude more sensitive than using a quadrant detector (QD) for beamshift measurements.
