Popis:	Low energy characteristic X-ray emission from Al2O3 monocrystalline specimens is measured under bombardment of 100 keV Xe+ ions. The electric field influence on emission of the X-rays of constitute elements in the specimens was investigated. The energy dispersive X-ray spectroscopy spectra show that the characteristic X-ray of Al-Kα seems to be depressed by the applied dc voltages, while the peak intensity of O-Kα was not notably influenced. The O-Kα peaks were broadened and the total counts increased as a higher dc bias was applied. It is possible that a dc electric field parallel to the target surface may influence the X-ray emission from it under ion bombardment.
