3D nanoscale imaging of individual spin labels

• Applicants: Dr. Philipp Neumann; Professor Dr. Jörg Wrachtrup; Dr. Andrea Zappe
• Subject Area: Analytical Chemistry
• Term: from 2015 to 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 276780336

In this project we plan to carry out 3D precision localization of individual electron spin labels. To this end we will combine 3D single spin scanning magnetometry with electron-electron double resonance (DEER). We plan to carry out DEER between NV and single spin labels. We will combine decoupling with DEER to enhance the distance range of the method. Further on we will combine DEER with nuclear memory to improve DEER resolution. We will apply the method to precision imaging of single spin labels, e.g. Gd spins. We plan to explore resolution by image test samples with multiple spins synthesized by members of the SPP. While most experiment will be carried out at low temperature we plan to carry out 3D localization of electron spins under ambient conditions.
