PhD Position in Wettability Control of Patterned Surfaces, University of Twente, Netherlands

PhD Position in Wettability Control of Patterned Surfaces, University of Twente, Netherlands.
We offer a Ph.D.-student position in the Solid State Physics group
(SSP) of the University of Twente.


The research of SSP is an integral part of the MESA+ Institute for
Nanotechnology. Well-defined morphological patterns and functional
patterned molecular coatings will be studied to improve control of the
wettability of surfaces. Both the macroscopic and microscopic features of such
structures and their collaborative effects will be studied. The
molecular coatings for wetting control will be applied by two different
techniques, microcontact printing and shadow-mask evaporation. Both the
influence of the length scale and the anisotropy of the patterns on the
macroscopic wettability are of interest. The combination of length scales
in the micron range with those in the nanometer range is promising for
gaining improved wettability control, especially in gradient patterned
surfaces. Nanometer sized structure will be implemented by means of ion
beam induced erosion, both in 0D (dots) and 1D (stripes).

This project aims at a fundamental investigation of the
interrelationships between roughness and functional coating. The laboratory scale
experiments will be performed with mainly optical tools (ADSA-P and
interference microscopy), combined with high-resolution microscopy (AFM and
possibly LEEM). The findings are thought to be relevant for application
in high-tech printing technology.

Organisation:
University of Twente, MESA+ Institute for Nanotechnology The MESA+
Institute for Nanotechnology at the University of Twente trains graduate
students and PhD-students and conducts interdisciplinary research in the
fields of nanotechnology, microsystems, materials science and
microelectronics.

Requirements:
For this position, we are searching for enthusiastic candidates with a
recent Masters degree in experimental or applied physics, physical
chemistry or a related discipline, and with a strong desire to investigate
uncharted waters. Preferably, you have some previous experience related
to the research topic. Knowledge of the standard experimental
techniques used in this work, i.e. optical and scanning probe microscopy, is
desirable.

Employment:
We offer an interesting temporary research position in a dynamic,
interdisciplinary and international environment. You will be appointed for a
period of one year, with an assessment within one year. A positive
assessment will secure the continuation of the appointment for another
three years. The salary starts at €1.933,- gross per month increasing to
€2.472,- gross per month in the fourth year. PhD students are
expected to complete their research with a thesis. Benefits and other
conditions of employment are in accordance with the Collective Labour Agreement
for Dutch Universities, including participation in `Stichting
Pensioenfonds ABP` for your pension.

Application:
To apply for this position, please send a detailed CV together with a
letter of motivation and preferably the names and postal or e-mail
addresses of two referees to: Prof. dr. ir. Bene Poelsema, MESA+ Institute
for Nanotechnology and Faculty of Science and Technology, University of
Twente, P.O. Box 217, 7500 AE Enschede, The Netherlands. Starting date:
