A stiff scanning tunneling microscopy head for measurement at low temperatures and in high magnetic fields
Abstract
We have developed a measurement head for scanning tunneling microscopy (STM) and specifically for spectroscopic imaging STM which is optimized for high mechanical stiffness and good thermal conductivity by choice of material. The main components of the microscope head are made of sapphire. Sapphire has been chosen from several competing possibilities based on finite element modeling of the fundamental vibrational modes of the body. We demonstrate operation of the STM head in topographic imaging and tunneling spectroscopy at temperatures down to below 2 K.
