A thermally stable Ni-based ohmic contact is one of the most attractive contact materials for developing superior GaAs devices. To understand the interface reaction between an Ni thin film and a GaAs wafer, a combined grazing-incidence and grazing-takeoff x-ray fluorescence (GIT-XRF) method was appl

โฆ Synopsis
In many technological applications layered materials have an increasing importance. Almost complete characterization of such materials can be achieved with glancing incidence x-ray analysis (GIXA). Within this technique, x-ray reรectivity and angle-dependent x-ray รuorescence measurements are combined, resulting in a structural and chemical analysis of the samples.

We have measured Au and Ni thin films on a quartz glass using both scanning tunnelling microscopy (STM) and glancing-incidence and -take-off x-ray fluorescence (GIT-XRF). The STM image shows that the film surface consists of grains of several tens of nanometres in size. Although the GIT-XRF method u
