Intrinsic Features on Surfaces
The detection of stable feature points is an important preprocessing step for many applications in computer graphics. Especially, registration and matching applications often require those points and depend heavily on their quality. In the 2D image case, scale space based feature detection is well established and shows unquestionably good results. For this reason, we generalize a scale space to...
متن کاملTopographic and electronic structure of cleaved SrTiO3(001) surfaces
The topographic and electronic structure of cleaved SrTiO3(001) surfaces were studied, employing samples that either had or had not been coated with Ti on their outer surfaces prior to fracture. In both cases, SrOand TiO2-terminated terraces were present on the cleavage surface, enabling in situ studies on either termination. However, the samples coated with Ti prior to fracture were found to y...
متن کاملAbsence of Fermi-level pinning at cleaved nonpolar InN surfaces.
Prior experimental work had found that the Fermi level at InN growth surfaces is pinned well above the conduction band edge, leading to strong surface band bending and electron accumulation. Using cross-sectional scanning photoelectron microscopy and spectroscopy, we show definitive evidence of unpinned Fermi level for in situ cleaved a-plane InN surfaces. To confirm the presence or absence of ...
متن کاملEvidence for potassium carbonate crystallites on air-cleaved mica surfaces.
Air-cleaved mica surfaces exhibit a high density of nanometer or micrometer size particles that have been ascribed to potassium carbonate formed as a reaction product of carbonaceous gases with potassium ions. Unambiguous evidence for this assignment has, however, never been presented. We study air-cleaved mica surfaces by high-resolution noncontact atomic force microscopy (NC-AFM) in ultrahigh...
متن کاملIntrinsic magnetism at silicon surfaces.
It has been a long-standing goal to create magnetism in a non-magnetic material by manipulating its structure at the nanoscale. Many structural defects have unpaired spins; an ordered arrangement of these can create a magnetically ordered state. In this article we predict theoretically that stepped silicon surfaces stabilized by adsorbed gold achieve this state by self-assembly, creating chains...
