The Research Training Group (RTG) 2767 „Supracolloidal Structures: From Materials to Optical and Electronic Devices“ of TU Dresden, funded by Deutsche Forschungsgemeinschaft (DFG), offers a position as

Research Associate / PhD Student (m/f/x)
(subject to personal qualifications, employees are remunerated according to salary group E 13 TV-L)

starting as soon as possible, initially limited for 3 years, with the option of extension. The period of employment is governed by the Fixed Term Research Contracts Act (Wissenschaftszeitvertragsgesetz-WissZeitVG). The position aims at obtaining further academic qualification (e.g. PhD).

Position:        RTG2767-A6
Investigators:    Dr. Bernd Rellinghaus / Prof. Dr. Andreas Fery
Terms:         75 % of the full-time weekly hours
Tasks:    In situ and in operando characterization of functional self-assembled nanostructures
Requirements:    excellent university degree (Master of Science or diploma) in physics, materials science, or chemistry; Experience in experimental transmission electron microscopy. Additional experiences in the processing of nanostructured or nanoparticulate materials are appreciated.

Description of the PhD task
The project aims at understanding and controlling self-assembly processes during both the growth and assembly of nanoscopic functional elements by using in-situ transmission electron microscopy (TEM). Here, the DNA-mediated assembly of nanomaterials and novel nano-actuators based on Au nanorods attached to DNA origamis shall be directly observed by liquid phase electron microscopy in order to identify and optimize kinetic parameters that govern the assembly processes. Also, the electrically biased switching of nano-actuators is planned to be monitored operando in the microscope. Since collateral beam damage is unavoidable in in-situ TEM, low dose strategies need to be developed and ex-situ control experiments using analytical high-resolution TEM are to be conducted to quantify and minimize such beam-induced artefacts.

About the RTG
The RTG 2767 aims to train a new generation of experts who will design materials made of supracolloidal structures from the drawing board to application in components. Nanoparticles are used in many optical and electronic components nowadays. Supracolloidal structures are complex superstructures composed of different nanoparticles, similar to how atoms are linked to molecules. This results in innovative, exceptionally promising optical and electronic properties that go far beyond those of the individual building blocks. To date, these structure-property relationships of the assembled particles are not adequately understood. The technological visions of these new materials include novel solar cells, field amplification for highly sensitive spectroscopy, biosensing applications where complex detection processes are made simpler, and even on-site sample examination using smartphones. In order to realize the technical complexity in the training, numerous institutions are connected within the RTG’s 2767 tight network, including various groups at the TU Dresden, the Universität Leipzig, the TU Dresden Research Cluster cfaed and the Dresden Center for Nanoanalysis as well as the Leibniz-Institut für Polymerforschung Dresden e. V., the Helmholtz-Zentrum Dresden - Rossendorf e. V. and the Kurt-Schwabe-Institut für Mess- und Sensortechnik Meinsberg e.V.
