Ti2SnC and Ti2InC Nanolaminates by Low Energy Ion Facility (LEIF) and Their Resistance Towards Ar+ Ion Bombardment

Concentration micropro®les in iron silicides induced by low energy Ar ion bombardment

Auger electron spectroscopy (AES) in conjunction with sputter removal by Ar‡ ions of only 120 eV has been used to determine the concentration micropro®les generated in polycrystalline Fe3Si, FeSi and FeSi2 samples by a preceding bombardment with Ar‡ ions of 1±5 keV. The conversion of the surface sensitive AES ptp-signals measured in dependence of the pro®ling ion ̄uence into concentration-versu...

Stress evolution in Si during low-energy ion bombardment

Measurements of stress evolution during low-energy argon ion bombardment of Si have been made using a real-time wafer curvature technique. During irradiation, the stress reaches a steady-state compressive value that depends on the flux and energy. Once irradiation is terminated, the measured stress relaxes slightly in a short period of time to a final value. To understand the ion-induced stress...

Flair: a Facility for Low-energy Antiproton and Ion Research

To exploit the unique possibilities that will become available at the Facility for Antiproton and Ion Research (FAIR), a collaboration of about 50 institutes from 15 countries was formed to efficiently enable an innovative research program towards low-energy antimatter-physics. In the Facility for Low-energy Antiproton and Ion Research (FLAIR) antiprotons and heavy ions are slowed down from 30 ...

Compositional changes on GaN surfaces under low-energy ion bombardment studied by synchrotron-based spectroscopies

LOW-ENERGY-ION ENHANCED DIFFUSION AT THE SURFACE OF METALS

Radiation enhanced diffusion at the surface of metals has been observed and studied for low-energy nitrogen ions at the surface of copper. The displacement of the target atoms during irradiation creates vacancies and other defects near the surface, thus enhancing the diffusion of implanted materials toward the surface and also into the solid. The mechanism has been studied here by a specia...
