New Review on precursors in FEBID Processes

In this collaboration with Michael Huth, we are trying to bridge the more chemical oriented experiments reported in literature with the actual FEBID process in order to entangle the complex process on the surface.

The paper is entitled "Precursors for Direct-Write Nanofabrication with Electrons" and will be published in the Journal of Materials Chemistry C. The review can be downloaded here.
