AbstractThin sputtered ceramic films deposited on ceramic substrates were subjected to either Kr+ or Xe+ ion bombardment for ion beam mixing studies in ceramic-ceramic systems. The amount of mixing if any was evaluated from Rutherford backscattering and Auger electron spectroscopy. In some instances ceramic films were deposited on epitaxial films or single crystal substrates for ion channeling analysis. No significant mixing was observed in any of the systems with ZrC. However, analysis of the interface in Si3N4/ SiC system indicates appreciable mixing and ion beam induced damage to the substrate. The mixing appears to be dose dependent for heavier ions.

Amorphous carbon films can be prepared with a large variety of structure and have been used in a number of technological applications. Many of their properties have been determined, but very little is known concerning the effect of pressure on their properties. In this work we investigate the influence of pressure of graphite-like amorphous carbon films on the density of states (DOS) using X-ray Excited Auger Electron Spectroscopy (XAES) and the second derivate method of the XAES. The films were deposited by ion beam deposition and simultaneously bombarded with argon, which is responsible for the variation of the film stress, reaching extremely high values (4.5 GPa). Marked variations of the density of states of the pπ, pσ, sp, and s components were observed with increasing stress.

AbstractSilicon coatings on niobium substrates were subjected to thermal, ion beam and laser mixing, and the effectiveness of the different methods for the synthesis of graded interfaces was compared. The resulting metal/silicon interfaces were characterized by X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES) and Rutherford backscattering (RBS).

Abstract It is shown that a focused ion beam (FIB) grounding technique can be used to alleviate charge buildup on samples that would otherwise charge in the electron beam to the point where analysis by Auger electron spectroscopy (AES) was limited or impossible. FIB grounding alleviates the sample charging and permits AES analysis. The grounding technique is quick, easy and well understood as it has been used extensively for voltage-contrast analysis. The technique is shown to be useful for enabling analysis on electrically isolated conductive features as well as insulating samples.
