Quantum optics with electron spin ensembles in semiconductors (Postdoc 3 years)
This project will explore the ability to map a quantum state carried by a light pulse onto a degree of freedom in solid state material, and vice versa. This may provide a new way for preparing entangled states in solid state. The work builds on recent experiments in the field that demonstrated how one can prepare, control, and detect quantum coherence stored on electron spins in semiconductors. Unique to this project is that it aims to exploit the advantage of working with spin ensembles, rather than individual spins in a quantum dot in an optical cavity. This allows for developing robust techniques for optical communication between solid-state quantum-computing devices. The approach aims at realizing quantum systems in semiconductors, that have a set of energy levels similar to that of alkali atoms, and similar selection rules for the optical transitions. In these systems, long-lived quantum superpositions of low-energy spin states can be controlled by optical control fields (addressing high-energy transitions), by exploiting a quantum interference between two transitions that are driven at the same time (techniques based on so-called Electromagnetically Induced Transparency, EIT). The realization of EIT with an ensemble of conduction band electron spins in a GaAs system is the first upcoming experiment in this project.

Physics and dynamics of individual unidirectional molecular motors (3 years Postdoc/4 years PhD)
There are several positions available on Graphene. Take a look at our research on graphene to get a further impression and contact prof.dr.ir. Bart van Wees if you need to know more.

Graphene Nanoelectronics and Spintronics (Postdoc 3 years)
This position will supervise and coordinate the activities of the graphene team. He/she will also represent the group on (international) meetings and conferences.

Spintronics and Valleytronics in Graphene Nanodevices (PhD Position 4 years)
This position aims at investigating the spin and valley degrees of freedom in graphene devices. For this graphene nanodevices will be fabricated and investigated electrically, both at room temperature and cryogenic temperatures. Special attention will be paid to the role of the quality of the graphene layers and the role of the graphene edges.

Spin and Charge Transport in Graphene Quantum Dots (PhD Position 4 years)
The focus of this position is to investigate the charge and spin degree of freedom in nanostructured graphene devices and graphene quantum dots. An inportant question that will be addressed here is how the spin relaxation and dephasing times change when the electronic carriers are confined in 1D and 0D structures.

Graphene based Sensors for Detection of (single) Molecules and Atoms, in Liquid or Atmospheric environments (PhD Position 4 years)
This position aims at investigating the potential for graphene based field effect devices as sentitive sensors (single atom/molecule) in both gaseous or liquid environments. This research will be performed in close collaboration with chemistry groups from the Zernike Institute for Advanced Materials at the University of Groningen.
