Low-temperature and high magnetic field dynamic scanning capacitance microscope
Low-temperature and high magnetic field dynamic scanning capacitance microscope
We demonstrate a dynamic scanning capacitance microscope (DSCM) that operates at large bandwidths, cryogenic temperatures, and high magnetic fields. The setup is based on a noncontact atomic force microscope (AFM) with a quartz tuning fork sensor for the nonoptical excitation and readout in topography, force, and dissipation measurements. The metallic …
