Postdoc One Ink

Do you want to work on cutting edge nanotechnology research? Are you interested in the physical chemistry and physics of colloidal quantum dot devices?

We are seeking a highly motivated Postdoctoral Researcher with a background in physics of opto-electronic devices to join the project “One Ink to Rule Them All:
Integrated Short-Wave Infrared Photodetectors and Light-Emitting Devices Based on III‑V Quantum Dots for Wearable Photonic Technologies (ONE INK)”, funded through the Photon Delta National Growth Fund programme.

ONE INK aims to develop a single printable quantum‑dot ink that can both emit and detect short‑wave infrared (SWIR) light, enabling a new generation of compact, low‑cost, and wearable health‑sensing technologies. Using III–V semiconductor nanocrystals, the project will create materials that make it possible to monitor key health markers without invasive blood tests. The ability to print light sources and detectors from one ink directly onto electronics simplifies manufacturing and supports the future of personalised, preventive healthcare.

The project will also employ a PhD student who will work alongside the Postdoctoral Researcher.

You will work in the NCFun group of Prof. Arjan Houtepen, with Dr. Tom Savenije as co‑supervisor. You will be embedded in a vibrant research environment and closely collaborate with QDI Systems (Groningen) and imec (Leuven). The position is part of a larger, interdisciplinary team working on the synthesis, characterization and device integration of nanomaterials for optoelectronic applications.

• Physical chemistry and photophysics of semiconductor nanomaterials
• The production of LEDs and photodiodes through a combination of solution and vapour phase deposition methods.
• Optical and electrical measurement to characterize and understand the limiting factors in the opto‑electronic devices.
• Linking nanocrystal structure, electronic properties and device performance

You have a completed PhD degree in physical chemistry, materials science, applied physics, or a closely related field. You combine a strong interest in the structure and properties of nanomaterials with a solid understanding of device physics.

• Opto‑electronic device fabrication and testing
• Characterization of semiconductor nanocrystals and their surfaces
• Time‑resolved or steady‑state optical spectroscopy

You enjoy working in a collaborative, interdisciplinary environment and are motivated to contribute to both fundamental understanding and technological development.

• A full‑time postdoctoral position at TU Delft in a leading European research environment
• Access to state‑of‑the‑art synthesis, characterization and device fabrication facilities
• Close collaboration with industrial and academic partners in the Netherlands and Belgium
• The opportunity to contribute to innovative semiconductor materials and device concepts with real‑world impact

For this position we are looking for a physicist or physical chemist with a completed PhD in device physics. You should combine a keen interest in the properties of nanomaterials with an understanding of the physics of optoelectronic devices. The ideal candidate has prior experience with the colloidal nanomaterials and opto‑electronic devices.
