摘要:
Mössbauer spectroscopy on57Co implanted into Si and Ge at doses between 1011and 1015atoms/cm2supports the single track amorphization model. Calculations based on linear cascade theory do not give quantitative agreement with the experiment.

摘要:
Modifications of subsurface alloy composition during high-temperature sputtering were studied using a comprehensive kinetic model that Includes Gibbsian adsorption, preferential sputtering, displacement mixing, radiation-enhanced diffusion, and radiation-induced segregation. Numerical solutions were obtained for a Cu-40 at.% Ni alloy under 5-keV Ar+ion bombardment as functions of time and temperature. The model predictions are in good qualitative agreement with recent experimental measurements.

摘要:
Ion implantation of 2 × 101531P+/cm2at 10 keV and furnace annealing at 750° C, 1/2 h, have been used to obtain n+-p junctions on (100) silicon samples having tetrahedrically textured surfaces. This texture was obtained by an anisotropic etching in a hot hydra-zine-water mixture. Morphological properties of the surface (dimension, homogeneity and characteristic of the tetrahedrons) have been analyzed and electrical properties of the implanted layers (sheet resistivity, carrier concentration profile) have been measured. The electrical characteristics of the textured samples are similar to those obtained using samples with flat polished surface; the tetrahe-dral structures are not damaged by the implantation process and they keep their antireflecting properties unaltered.
