Inspired by the highly parallel, fault tolerant, and energy efficient manner our brains work, new materials are needed that can emulate the operation of the human brain for applications in, for example, next generation neuromorphic computing. We aim to create devices that emulate synaptic behavior at the molecular length-scale based on new types of multi-functional molecular switches that evolve and learn rather than toggle between predefined on/off states. These dynamical switches consist of multiple molecular components where fast electron transfer is coupled to slow reversible chemical reactions that lead to rich switching dynamics of the conductivity depending on the history of the switches. We have recently identified interesting candidates, but the challenge is to develop stable switches that can be readily incorporated in devices that mimic basic synaptic function needed to develop artificial neural networks.

Your task is to develop and prepare these new switches and study their dynamic behavior, improve their stability, and investigate in detail their switching mechanisms.

The fully financed 4yr PhD position is available at the University of Twente (UT), The Netherlands, within the Faculty of Science and Technology in the Nijhuis group of Hybrid Materials for OptoElectronics (HMOE). At the UT you are part of the unparalleled possibilities at MESA+ Institute for Nanotechnology and BRAINS (Center for Brain-Inspired NanoSytems).


We seek for a colleague with a background in synthetic chemistry, surface chemistry, physical chemistry with a broad interest in nanoelectronics, switchable/smart materials, and characterization of such materials. Fabrication skills and hands-on experience with electrical measurements, or electrochemistry, are highly desirable.

  • You have a MSc degree in chemistry, surface chemistry, or physical chemistry, or similar
  • You have demonstrated experience in the preparation/characterization of molecular switches, smart materials
  • You have affinity with the development of new or extending existing characterization techniques.
  • You are an excellent team player in an enthusiastic group of scientists and engineers working on a common theme.
  • You are fluent in English and able to collaborate intensively with industrial and academic parties in regular meetings and work visits.


The UT provides a dynamic and exciting scientific environment, lots of sports facilities (and other activities), and a green and lively campus. We offer a fulltime position with excellent working conditions in an inspiring multidisciplinary and international environment involving local and overseas collaborations:
  • A full-time 4-year PhD position;
  • Excellent mentorship in a stimulating research environment with excellent facilities;
  • The gross monthly salary starts with € 2395,- in the first year and increases to € 3061,- in the fourth year of your employment;
  • A holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.3%;
  • A solid pension scheme;
  • Minimum of 29 holidays in case of full-time employment;
  • Professional and personal development programs.
