UNIQUE SCANNING TUNNELING MICROSCOPE DESIGNED & MADE IN CANADIAN UNIVERSITY A FEW YEARS AFTER FIRST INVENTION OF STM IN 1981. TEAM AT DALHOUSIE MADE TWO DIFFERENT STMS IN 1986 & USED THEM FOR NUMEROUS EXPERIMENTS, PARTICULARLY EXPERIMENTS RELATING TO MICROBIOLOGY.
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 WON 1986 NOBEL PRIZE IN PHYSICS. THIS ONE IS 1STOF TWO DIFFERENT & UNIQUE DEVICES DEVELOPED IN 1985-1986 IN PHYSICS DEPT. OF DALHOUSIE UNIV. THIS VERSION USED PIEZO RODS WITH MICROMETER COARSE APPROACH, WITH THERMAL COMPENSATION.
