Figure 1: We have 3He based and fully ultra-high vacuum compatible scanning tunneling microscope facilities available. The figure shows our first machine of that kind, which was home-built using an Oxford Instruments cryostat. The system has a base temperature of 315 mK (base temperature hold time 30 h) and a magnetic field of 12 T that can be applied perpendicular to the sample surface.
