Hochempfindliches bildgebendes Magnetometer mit Sub-Nanometer Auflösung

该项目旨在实现基于金刚石自旋的扫描磁力计的单电子自旋灵敏度和亚纳米尺度空间分辨率。为此，无论是超纯金刚石材料的定制单晶金刚石尖端还是超净金刚石纳米晶体，都应该以原子精确的方式生产，植入并集成到现有的AFM装置中。我们打算首次对表面上的单电子自旋成像。此外，我们将测量烟草花叶病毒的单个铁蛋白分子和单个自旋标签的磁场。为了获得快速弛豫电子自旋，我们将把我们的设置扩展到低温操作，并将其应用于金属蛋白成像。我们的方法一旦成功，就有可能在从固态物理到蛋白质结构分析的各个科学领域彻底改变磁场成像。

The project aims at achieving single electron spin sensitivity and sub nm scale spatial resolution for a diamond spin based scanning magnetometer. To this end either custom made single crystalline diamond tips out of ultrapure diamond material of ultraclean diamond nanocrystals should be produced atomically precisely implanted and integrated into the existing AFM set-up. We intend for the first time to image single electron spins on surfaces. In addition, we will measure the magnetic field of single ferritin molecules and single spin labels on tobacco mosaic viruses. To get access to fast relaxing electrons spins we will extend our set up to low temperature operation and apply it to imaging metalloproteins. Our approach, once successful, has the potential to revolutionise magnetic field imaging in various areas of science, ranging from solid state physics to protein structure analysis.
