pA-STM Scanning Tunneling Microscope, A.P.E. Research (CAT#: STEM-M-0061-LKN)

A.P.E. Research pA-STM Scanning Tunneling Microscope is a very powerful Scanning Tunneling Microscope allowing the mapping with atomic resolution in air even for high resistive materials. The pA STM can be equipped with different scanners with ranges from 3 μm to 25 μm. By tunneling down to 500 fA the pA-STM is suitable to measure high resistive materials like the self assembled molecules (SAM).
