A low-temperature vector-field ultrahigh vacuum scanning tunneling microscope facility for the study of quantum materials

Scanning tunneling microscopes (STM) play a very important role in the study of quantum materials by correlating electronic properties with structures at the atomic scale. In my poster, I will present our home built ultrahigh vacuum STM facility with a base temperature of 1.2 K. A 3 T vector field as well as 9 T perpendicular to the sample surface can be applied. It features a compact design and has a long holding time. Updating with a 3He refrigerator is ongoing, which will enable us to reach a higher energy resolution.
