In-Plane Fabricated Insulated Gold-Tip Probe For Electrochemical And Molecular Experiments

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Peter Van der Wal, Yexian Wu

In this contribution we present a scanning probe with a gold-tip completely encapsulated with insulator all the way to the apex. The probe fabrication is unique owing to an in-plane arrangement in which the width of the cantilever is defined by deep reacti ...

Complex nanostructures in PMMA made by a single process step using e-beam lithography

Nico de Rooij, Michel Studer, Sebastian Gautsch

We present results on the single step fabrication of autocentered nanopillars with surrounding circular rim. This particular 3-dimensional shape is created by the energy density distribution of incident and backscattered electrons and reflects the dual beh ...

Microcolumn design for a large scan field and pixel number

Nico de Rooij, Sebastian Gautsch

A different approach in microcolumn design is presented, aiming at a large number of pixels at minimal probe size for the deflected beam. An optimization routine resulted in a seven times magnifying column featuring a more than 7×7 mm2 scan field at 40 mm ...
