Scanning tunneling microscopy (STM)

Scienta Omicron multi-instrument vacuum unit

 

 

Scienta Omicron is a scanning tunneling microscope for room temperature measurements. It gives atomic scale information about surface properties, also from surface defects, which are harmful to surface passivation.This setup includes an Ar-ion sputtering to clean a sample surface and  a diffraction (LEED) instrument to study crystal structure of surfaces if a surface is crystalline or amorphous. Also,  the spectroscopy mode (STS) allows measuring of the electronic structure of surfaces.

For more information, contact Pekka Laukkanen.

Specifications:

  • Room temperature measurements
  • Background pressure in ultrahigh vacuum range, 10-10 mbar.
  •  Suitable samples: solid plates (6 mm x 12 mm), or material which can be attached on the plate
  • Includes LEED and STS
