Jason: Home-Built Scanning Tunneling Microscope System

Home-Built Scanning Tunneling Microscope System

 

Jason is our small home-built STM system, made for low-current measurements of organic surfaces under ambient conditions or under aqueous / organic solvents.  It is currently driven by our analog electron controller, but we intend to replace this with our in-house DSP-based system in the near future.

 

Characteristics

  • 20 pA noise floor
  • Analog and DSP control systems
  • Inchworm coarse approach mechanism
  • Four-sector + centre electrode scan tube configuration
  • Vertical resolution ~0.07 Å
  • Lateral resolution ~1-2 Å
  • System is mounted on optical table that is suspended via rubber vibration isolation mounts from steel frame
