Microscope: Scanning Probe - Variable Temperature

Sample Characterization Tools

Schematic model of TiO₂(110) surface

This state-of-the art surface science tool comprises multiple complementary probes of surface phenomena. The system includes a pair of interlocked ultrahigh vacuum chambers-scanning probe chamber and sample preparation/characterization chamber with the capabilities indicated in the accompanying list.

Omicron variable temperature ultrahigh vacuum scanning probe microscope instrument featuring STM and NC-AFM.
