New mkSTM in Jülich: design, perfomance and first results

In my talk, I will introduce our new UHV STM operating at temperatures down to 26 millikelvin and high magnetic fields of up to 8 Tesla. The peculiarity of our setup is that it uses an adiabatic demagnetisation refrigerator (ADR) to reach its base temperature. Since this is the first instance of ADR use for STM, I will describe our microscope’s characteristics and modes of operation in some detail, after which I will demonstrate the first measurements we performed on superconducting Al(100) surface in the attempt to clarify the issue of our mkSTM junction’s effective electronic temperature.
