An. Kiselev et al., X-ray irradiation at subthreshold energies modifies the surface micromorphology of epitaxial silicon layers on sapphire, TECH PHYS L, 27(9), 2001, pp. 725-727
Atomic force microscopy investigations revealed a change in the surface mic
rorelief of the heteroepitaxial silicon films on sapphire substrates after
pulsed X-ray irradiation at an energy of E less than or equal to 140 keV. (
