Nanoscale self - affine surface smoothing by ion bombardment

Topography of silicon surfaces irradiated by a 2 MeV Si + ion beam at normal incidence and ion fluences in the range 10 15 − 10 16 ions/cm 2 has been investigated using scanning tunneling microscopy. At length scales below ∼ 50 nm, surface smoothing is observed; the smoothing is more prominent at smaller length scales. The smoothed surface is self-affine with a scaling exponent α = 0.53 ± 0.02....

Nanoscopic surface modification by slow ion bombardment

We present systematic scanning tunneling microscopy (STM)/atomic-force microscopic (AFM) investigations on nanoscopic defect production at atomically clean surfaces of SiO2, Al2O3 and highly oriented pyrolytic graphite (HOPG) after bombardment by slow (impact energy ≤ 1.2 keV) singly and multiply charged ions under strict ultra-high vacuum (UHV) conditions. Combined STM and AFM studies show tha...

X-ray production by ion bombardment

2014 The available experimental and theoretical results on ion induced X-rays are briefly surveyed. From experimental data it may be concluded that the mechanism for inner shell excitation by heavy ion-atom collisions is different from that for proton-atom collisions. The latter are described successfully in Plane Wave Born Approximation (PWBA) and in classical Binary Encounter Approximation (B...

Tailoring magnetic anisotropy gradients by ion bombardment for domain wall positioning in magnetic multilayers with perpendicular anisotropy

UNLABELLED Graded anisotropy magnetic materials possess a coercive field changing laterally with position. A simple fabrication procedure to produce such an anisotropy gradient in a polycrystalline Au/Co layer system without lateral thickness variation and with perpendicular magnetic anisotropy, prototypical for a large variety of thin film systems, is shown. The procedure uses light-ion bombar...

Ion Bombardment of Interplanetary Dust

The recent discovery of ion tracks in interplanetary dust and the increasing evidence for carbon and carburized materials in these objects are strongly suggestive that chemical processing by energetic charged-particle bombardment has occurred during the dust lifetimes. The track density gives a measure of the total ion fluence experienced by the grains. We use this information and laboratory da...
