Fabrication and Characterization of CNT-Based Smart Tips for Synchrotron Assisted STM
SEM images of the radial cross section (top view) of a 570 nm SiO2-Pt90Ir10 tip (a); during focused ion beam (FIB) fabrication using circular/donut-shape pattern (b–e), tip was placed parallel to ion beam and 52° from electron beam. About 1 μm long Pt90Ir10 pillar with a radius of curvature less than 100 nm was exposed after fabrication.
