The structure of the 3 × 3 -R30° reconstruction on the (0001) surface of silicon carbide before and after initial oxidation at room temperature was determined with reflection high-energy electron diffraction (RHEED) rocking curves in the one-beam c

We have determined the structure of the 4H–SiC(0 0 0 1)-3 × 3 surface after exposure to small amounts of molecular oxygen at room temperature using surface X-ray diffraction. The 3 × 3 reconstruction remains until at least an exposure of 10,000 L

To gain insight into surface processes in plasma processing, basic ion beam experiments are performed on two representative polyatomic-ion species: hydrocarbon ions CH_x^+ for deposition processes and fluorocarbon ions CF_x^+ for etching processes (x

Fluorocarbon ions ( CF+ 3, CF+ 2 and CF+) are mass-selected from a CF4 plasma and irradiated onto aluminum surfaces at energies up to 140 eV, to investigate the surface processes relevant to reactive ion etching. The irradiation of a CF+ x beam (x=1-

A single species of hydrocarbon ion CH x + (x=2, 3, 4) is extracted from an inductive plasma via a mass filter and irradiated onto aluminum surfaces at the incidence angle of 45°. Measurements of ions scattered in the specular direction revealed two
