6208.1:
Bismuth Hall probe on a plastic cantilever
Abstract
The aim of this project is the development of a new technology for low cost fabrication of bismuth Hall sensors of dimensions down to 100 nm (possibly 20 nm) on plastic cantilevers. The realized devices will allow magnetic imaging with effective spatial resolution better than 100 nm and magnetic field resolution better than 100 mT/Hz1/2.
This feasibility study is the crucial technological step towards the realization of a high performance scanning Hall probe microscope (SHPM) for non-invasive imaging of magnetic nano-structures.
