Project title: Next-Generation of Magnetometers
In DTU Energy, my research focuses on the fabrication of extraordinary magnetoresistive (EMR) devices and Hall magnetometers-based 2D materials with novel geometric configurations. Among van der Waals materials, graphene is chosen as one of the most appealing candidates for EMR devices because of its intrinsically high carrier mobility and its ability to reach extremely low carrier densities. Concentric circular devices, bar-shaped devices and more complex multi-branched devices (see illustrated Figure from [1]) will be fabricated using heterostructure of hBN/Gr/hBN to evaluate the effect on magnetoresistive performance. As a part of the BIOMAG project, our aim is to achieve subpicotesla sensitivity in detecting magnetic field, which will advance technologies employed in neuroscience, data storage and beyond.
