Multiple integrated tips scanning probe microscope with pre-alignment components
10663484 · 2020-05-26 · ·

Device and system for characterizing samples using multiple integrated tips scanning probe microscopy. Multiple Integrated Tips (MiT) probes are comprised of two or more monolithically integrated and movable AFM tips positioned to within nanometer of each other, enabling unprecedented micro to nanoscale probing functionality in vacuum or ambient conditions. The tip structure is combined with capacitive comb structures offering laserless high-resolution electric-in electric-out actuation and sensing capability. This platform-on-a-chip approach is a paradigm shift relative to current technology based on single tips functionalized using stacks of supporting gear: lasers, nano-positioners and electronics.
