Microscope Probe Having an Ultra-Tall Tip

Atomically sharp micro-fabricated tips are used in atomic force microscopy (AFM) for scanning near-field microwave microscopy (SNMM) to create an image of the tiny topography on or under a surface. Th...

Tuning Optical Microcavities

A whispering gallery mode (WGM) is a type of electromagnetic wave that travels around a concave surface. Such waves can propagate at the edge of a very small structure called an optical microcavity. W...
