Our laboratory is equipped with a combined Low-Temperature Scanning Tunneling Microscope/Atomic Force Microscope (LT-STM/AFM) operating at liquid Helium (<5K) and liquid Nitrogen (<78K) temperatures and under ultra-high vacuum (UHV) conditions. The guidance of light into and out of the tip-sample junction is realized via two dedicated optical accesses to the microscope in combination with in-situ lenses attached close to the probe tip-sample junction. An additional optical access to the junction allows single-atom deposition onto the cold sample within the microscope. We have standard in-situ tip and sample preparation techniques that we continuously expand to our needs. We are equipped with an Acton Pro Spectrometer with a cooled CCD camera for analyzing the light emission from the junction and with different laser sources for light excitation of the junction.
As a growing group we are developing novel instrumental setups tailored for our research objectives.
