In-plane fabrication of insulated gold-tip probes for electrochemical and force spectroscopy molecular experiments
Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Peter Van der Wal, Yexian Wu
A new and versatile fabrication process of insulated gold tip probes for atomic force microscopy (AFM) is presented by Wu et al. (In-plane fabricated insulated gold-tip probe for electrochemical and molecular experiments, in: 2013 IEEE 26th International C ...
Elsevier2014Batch fabrication of gold-gold nanogaps by E-beam lithography and electrochemical deposition
Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Yexian Wu
We report on the successful development of a well-controlled two-step batch nano-fabrication process to achieve nanometer-size gaps at the wafer scale. The technique is based on an optimized electron-beam lithography process, which enables the fabrication ...
Institute of Physics2013In-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 ...
IEEE2013Development of Passivated Heterogeneous Metal Nanogaps Using E-Beam Overlay Techniques
Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Yexian Wu
We present a planar nanogap structure with heterogeneous metal electrodes separated by a distance of tens of nanometers. This asymmetric nanodevice is meant for metal/molecule/metal transport analysis. The heterogeneous aspect of the metal electrodes is me ...

Nico de Rooij, Sebastian Gautsch, Yexian Wu
We present a much simpler and high-throughput method compared to mechanically break junctions (MBJ) and electro-migration, to produce a heterogeneous nanogap, directly using electron beam lithography and metal lift-off technology. Au – Pt and Au – Pt silic ...
