What can be done with it?
Scanning tunneling microscopy and spectroscopy:
- Structural and electronic characterization with atomic resolution.
- High-resolution structural characterization with CO functionalized tips.
- Band structure characterization in reciprocal space by means of quasiparticle interference patterns.
- Spin-polarized STM in constant height/current mode.
- Continuous measurements of magnetic contrast while driving the external field. Hysteresis loops and single atom magnetization curves.
- Spectroscopy of low energy excitations such as inelastic spin-flip and Kondo effect.
- Non-collinear magnetic ordering.
- Temperature range: 1.2 to 10 K (Joule-Thompson refrigerator)
- Magnetic field: Dry-split coil providing an axial field up to 3 Tesla (maximum rate 0.1 T/min).
- LHe hold time: 100 hours
- LN2 hold time: 80 hours
- Z topographic noise: 1-2 pm peak-peak; <500 fm/(Hz)^(1/2)
- In-situ tip exchange.
