Key features:

• Atomic resolution
• Low tunneling currents (up to 500 fA)
• High versatility

pA-STM 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).
