Towards time resolved single spin measurements.

Master thesis | Physics (MSc)

In this work, the possibility to measure time- and spatially resolved spin fluctuations using Scanning Tunneling Microscopy is investigated. By using an impedance matching circuit as described in [1], the bandwidth of conventional STM can be increased opening up possibilities for new kinds of experiments. When combined with the technique of spin-polarized STM, it theoretically becomes possible to track spin states of individual atoms. Here, we present an overview of existing literature on this topic and propose several experiments to test this hypothesis. Finally, with a python simulation, we test the viability of EPR-STM measurements on a single atom and provide directions to expand upon this work.
