Applications are invited for a postdoc position to work on an experimental project investigating the properties of novel quantum emitters in single layer and van der Waals bonded 2D materials. The project is funded through an ERC consolidator project and will be carried out at the Department of Physics at the Technical University of Denmark in close collaboration with both material scientists and theoretical physicists.
Solid state defect centres with allowed optical transitions and spin-properties are highly relevant as quantum light sources and quantum sensors with unprecedented spatial resolution and sensitivity. This project aims to investigate defect centres mainly in 2-dimensional materials, but also other material systems with a wide bandgap and stability. How do phonons impact the level dynamics, the coherence, and the efficiency of emitting a photon? Can the emission wavelength be tuned over a broad range and is emission in the telecom band possible? In this project, we will apply single photon resolved optical spectroscopy and try to obtain a quantitative understanding of emitters in novel solid-state materials. The project will be closely linked to our efforts on quantum sensing and quantum optics based on reading out the spin state of single defects in diamond.
The successful postdoc candidate will be part of the Quantum Physics and Information Technology group (QPIT) at the Department of Physics at DTU and the centre for macroscopic quantum states (bigQ). The project involves tight collaboration with the computational atomic scale design group (CAMD). The QPIT group is at the very forefront of international research in quantum optics, quantum opto-mechanics, and diamond-based quantum sensing. In this group, you will work in an international team of researchers in an informal working environment. Furthermore, you will become part of a collaborative network of experts including material science and theoretical physics, in particular the section for computational atomic scale design group (CAMD) at DTU Physics. This project will have access to on-site and state-of-the-art experimental facilities.
Responsibilities and tasks
This postdoc position will target optical investigations of quantum emitters and the successful candidate is expected to perform in:
- Design, construction and maintenance of a state-of-the-art confocal microscope nano-meter spatial and single photon resolution.
- Simulation of the experimental observations with for instance energy level schemes and corresponding rate equation models.
- Operation of cryogenic setups for sample and detector temperature control.
The exact research activities will be continuously adapted to ensure high relevance and impact.
Candidates should have a PhD degree in physics, photonics, material sciences or equivalent and must have experience working with optical setups. The successful candidate is expected to have experience and expertise in one or more of the following subjects:
- Expertise in optical spectroscopy.
- Background in quantum optics or physics.
- Experience in constructing and operating optical setups.
Furthermore, the successful candidate is expected to be
- self-motivated in scientific research,
- has Independent problem-solving skills,
- has good communication skills in English, both written and spoken, and
- has experience with international collaborations.
