Algorithms for Scanned Probe Microscope Image Simulation, Surface Reconstruction , and Tip Estimation
TL;DR: Treatment of the tip-surface interaction as a simple geometrical exclusion allows calculation of many quantities important for SPM dimensional metrology and Blind reconstruction, previously demonstrated only for simulated noiseless images, is here extended to images with noise or other experimental artifacts.
Journal ArticleDOI
Nanoindentation of polymers: an overview
TL;DR: A review of the application of instrumented indentation devices to the measurement of the elastic modulus of polymeric materials is reviewed in this paper, which includes a summary of traditional analyses of load-penetration data and a discussion of associated uncertainties.
Journal ArticleDOI
Morphological estimation of tip geometry for scanned probe microscopy
TL;DR: In this paper, a mathematical morphology is used to derive, for each point on an image, a corresponding bounding surface for the tip, which can be used to estimate the tip shape.
Journal ArticleDOI
Experimental test of blind tip reconstruction for scanning probe microscopy

TL;DR: In this paper, the authors compare blind reconstruction results to those obtained by scanning electron microscopy for two diamond stylus profiler tips, one of which has a gentle shape and the other a more complicated profile.
Journal ArticleDOI
Formation of Si(111)-(1×1)Cl
TL;DR: In this paper, the structural modifications induced by Cl upon reaction with Si(111)-(7\ifmmode\times\else\texttimes\fi{}7) were studied using scanning tunneling microscopy.
