Function

DEVICE FOR STUDYING & IMAGING INDIVIDUAL ATOMS ON SURFACES OF MATERIALS, BASED ON TUNNELING OF ELECTRONS BETWEEN TIP OF PROBE & SURFACE OF SAMPLE.

Technical

STM, WHICH ENABLED SCIENTISTS TO SEE ATOMS, WAS INVENTED IN EARLY 1980'S BY BINNIG & ROHRER (OF IBM ZURICH), WHO WERE AWARDED 1986 NOBEL PRIZE IN PHYSICS. THIS ONE IS 2ND OF TWO DIFFERENT & UNIQUE DEVICES DEVELOPED IN 1985-1986 IN PHYSICS DEPT. OF DALHOUSIE UNIV.
