PhD Position

in experimental Physics

Your tasks

A PhD position is available at the Laboratory for Neutron Scattering  
of the ETH Zurich and Paul Scherrer Institut (PSI), Switzerland to  
explore the interplay between non-magnetic and magnetic colloids and  
the phase behavior of such mixtures.
Suspensions of colloidal particles are of great interest in Soft  
Condensed Matter Physics due to their applications in many industries  
such as food processing but also due to their potential for the  
fabrication of tailored structures on the nano- and micrometer scale  
and due to their use as model systems. Their phase behavior and many  
of their properties can be controlled by tailoring the interactions  
between the colloidal particles or by the application of external  
fields. Suspensions of ferro- or paramagnetic colloidal particles -  
ferrofluids - show interesting rheological and structural properties  
that can be tuned with an external magnetic field. In mixtures of non- 
magnetic and magnetic colloids, structural ordering among the non- 
magnetic particles is generally facilitated by the magnetic colloids  
in a magnetic field. As ferrofluids are opaque, neutron- and X-ray  
scattering experiments are planned. Both techniques are available at  

Your profile

You have a diploma or master’s degree in Physics, Chemistry, or  
Materials Science as well as good knowledge in statistical Physics  
and some previous knowledge in Soft Condensed Matter Physics.  
Furthermore, you enjoy both experimental and theoretical work.  
Written as well as spoken English are required. The accompanying  
educational PhD program and final PhD exam is at ETH Zürich. The  
workplace is at Paul Scherrer Scherrer Institute in Villigen,  

We are looking forward to your application.
