Abstract
We describe the design and development of a compact low temperature XY stage scanning tunneling microscope dedicated to operation at low temperatures, in high magnetic fields, and in an ultrahigh vacuum environment. The system features a homemade compact scanning tunneling microscope (STM) head coupled to an inertially driven horizontal slider which allows a two-dimensional coarse positioning of the tip over 6×3mm2 with submicronic resolution. We also describe the geometry used to avoid coupling between the three-dimensional coarse and fine movements. To demonstrate the mechanical stability of the STM we display atomic resolution and large scale imaging. We illustrate the capabilities of our system by performing scanning tunneling spectroscopy on PbMo6S8 microcrystals.
