Chemical forces on surfaces have a central role in numerous scientific and technological fields, including catalysis, thin film growth and tribology. Many applications require knowledge of the strengt...
Abstract
An Ni-Si-Ni Schottky barrier sensor is used to sense 0.032 nm (0.064 nm peak-to-peak, 0.023 nm RMS) displacement of an optical beam incident on the sensor. This spatial resolution is more th...
