Introduction
Rohrer, from IBM research laboratories, invented a new type of microscope called a scanning tunnelling microscope (STM). 
Scanning Tunneling Microscopy (STM)
Scanning tunnelling Microscopy (STM) relies on “tunnelling current” between the probe and the sample to sense the topography of the sample.

Techniques
There are many varieties of scanning probe microscope (SPM) techniques ranging from the most common which are atomic force microscopy (AFM) and scanning tunnelling microscopy (STM), to more specialised instruments such as the near-field scanning optical microscope (NSOM/SNOM), tip-enhanced Raman microscope (TERS), and lateral force microscope (LFM) among others.
