We describe a three axis vector magnet system for cryogenic scanning probe microscopy measurements. discuss the support and power supply, consisting of compact way 100 A current source. obtain tilted magnetic fields in all directions with maximum value 5T along z-axis 1.2T XY-plane fields. tunneling microscopy-spectroscopy (STM-STS) set-up, operating dilution refrigerator, which includes new high voltage ultralow noise piezodrive electronics level due to vibrations. STM images STS maps show...
A Scanning Tunneling Microscope (STM) is one of the most important scanning probe tools available to study and manipulate matter at nanoscale. In a STM, tip scanned on top surface with separation few Å. Often, tunneling current between sample maintained constant by modifying distance apex through feedback mechanism acting piezoelectric transducer. This produces very detailed images electronic properties surface. The nearly always made using digital processing circuit separate from user...
