PMMA is removed by catalytic supported air thermal annealing. The polymer is completely removed where palladium is deposited while the gold covered SiN surface is left with the polymer layer - read more |
Non-destructive Holographic Imaging of DNA by Coherent Low-Energy Electrons - DNA has been exposed to 100.000.000 low-energy electrons per square-nanometer. Despite this vast dose, no sign of radiation damage has been observed - read more |
Low-energy electrons are sensitive to local electric fields. This might lead to a possibility of detecting individual charges as well as charge transfer- or transport-processes in biological molecules. |
The often discussed (but less often understood) double-slit experiment with electrons. The experimental three ingredients are: a coherent electron source - two nanometer-sized slits (holes in our case) milled in a thin film - and a spatial detector for low-energy electrons placed at some macroscopic distance away. It also needs proper means to keep everything well fixed and controlled in space. |
