A collaborative effort involving ZFPiN students, PhD candidates, and academic staff has resulted in a new scientific publication in the prestigious IEEE Electron Device Letters. The article was prepared in cooperation with researchers from the Łukasiewicz Research Network – Institute of Microelectronics and Photonics and represents another step in our ongoing research on graphene-based magnetic field sensors designed for operation in extreme environments

The paper, entitled “Monotonic High-Field Hall Response of Graphene Devices up to 11 T”, presents the results of investigations of graphene Hall-effect sensors exposed to magnetic fields of up to 11 T. The study demonstrates that graphene-based devices maintain a monotonic and virtually undistorted response throughout the entire investigated magnetic-field range, whereas conventional InSb-based semiconductor Hall sensors exhibit significant signal distortions associated with magnetoresistance effects. These findings further confirm the potential of graphene as a platform for magnetic-field sensing in demanding environments involving both multi-tesla magnetic fields and cryogenic temperatures.

A substantial part of the experimental work was carried out during a measurement campaign at the Institute of Low Temperature and Structure Research, Polish Academy of Sciences (INTiBS PAN) in Wrocław, where access to high-field magnet infrastructure enabled experiments in multi-tesla magnetic fields. We previously reported on this campaign in our news article >>> HERE <<<

The publication represents another step forward in the development of graphene-based sensor platforms intended for operation under extreme environmental conditions. We are particularly pleased that the article is the result of collaboration between researchers at different stages of their scientific careers and reflects the joint efforts of several cooperating research institutions.

The article has been published in the Open Access format. The full paper is available >>> HERE <<<
