Transferred Graphene as a Conductive Layer on a Thin Alumina Membrane: Investigating the Feasibility to use Graphene as Conductive Layer in a Timed Photon Counter

For this Master thesis the possibility was explored to use a monolayer of graphene as conductive layer, instead of sputtered titanium nitride (TiN), on 25 nm thick aluminium oxide and magnesium oxide membranes. These membranes will be used in a new and faster variant of a vacuum electron multiplier (e.g. the Photo Multiplier Tube (PMT)). These...

Ultra-Thin Integrated ALD Alumina Electron-transparent Windows for Nanoreactor Applications

<br/>Nanocatalysis has received considerable attention in the scientific community due to their superior reactivity compared to their macro-sized counterparts. MEMS nanoreactors allow scientists to view these reactions in-situ. This opens up doors to finally understanding the underlying mechanisms of the nanocatalyst's effectiveness, which may...
