The OPC is one of the most important component in the electrophotography process. So far its surface defects which degrade print quality were inspected by human-eye. We have developed the OPC surface inspection system employing an image processing technique. In this paper, we describe (1) an optical system to get the OPC surface image, (2) its analysis algorithm to specify the various defects a...
The axon hillocks and initial segments of pyramidal cell axons can be clearly recognized in electron micrographs of the somatic sensory cortex. The initial segment is characterized by three features: bundles of neurotubules linked together by electron-dense bands, a layer of dense material attached to the inner surface of the plasma membrane, and small membranebound dense bodies. All of these e...
The influence of the charge state q on surface modifications induced by impact individual fast, heavy ions muscovite mica was investigated. Beams 593 MeV 197Auq+ with well-defined initial states over a relatively broad range values (30 to 51) and at different irradiation geometries were used. At normal incidence, features are rounded protrusions (hillocks) ≳20 nm in diameter. grazing angles, be...
Upon impact on a solid surface, the potential energy stored in slow highly charged ions is primarily deposited into the electronic system of the target. By decelerating the projectile ions to kinetic energies as low as 150 x q eV, we find first unambiguous experimental evidence that potential energy alone is sufficient to cause permanent nanosized hillocks on the (111) surface of a CaF(2) singl...

Abstract Regarding deep-ultraviolet optical device applications, face-to-face annealed sputter-deposited AlN (FFA Sp-AlN) is a promising alternative to the conventional metalorganic vapor phase epitaxy (MOVPE)-prepared templates on sapphire substrates. However, FFA Sp-AlN tends exhibit AlGaN growth-related hillock generation and surface morphology deterioration. In this study, we optimized sput...
