Job Description
Departments Department of Electrical Engineering
Introduction
Eager to bridge photonics and terahertz technology Develop terahertz phototransistors in a unique double PhD degree: 2 years at TU/e (NL) 2 years at TU Darmstadt (DE) starting from November 2025. Create devices for breakthrough terahertz applications.
Job Description
How can we unlock the potential of terahertz (100 GHz10 THz) waves for transformative applications in security medical imaging and wireless communication In this PhD project you will pioneer novel phototransistor technology to generate and amplify terahertz radiation with unprecedented efficiency. Your core challenge: designing fabricating and characterizing semiconductor devices that convert laser light into high-power terahertz signalsbridging a critical gap in todays photonic systems.
Your Research
You will:
- Design and optimize semiconductor heterostructures for terahertz phototransistors.
- Grow semiconductor layers and fabricate devices usingTU/es state-of-the-art cleanroom facilities.
- Characterize devices using dual continuous-wave lasers or ultrafast pulsed lasers measuring THz emission via on-chip antennas.
- Working with theTerahertz Nanophotonics and Integration Technology Lab (TNIT) at TU/e andTU Darmstadts Terahertz Devices and Systems Lab (TSYS) (Prof. Sascha Preu) in a unique double-degree program.
- Validate results in THz labs at both universities and publish breakthroughs in top journals/conferences.
Societal Impact
Your work will enable non-invasive cancer detection ultra-secure communications and next-generation THz devicesaddressing global challenges in healthcare and digital infrastructure.
Research Environment
Youll join a dynamic internationally diverse team at TU/esIntegrated Circuits Group. Our collaborative culture fosters innovation with shared facilities including:
- TU/e NanoLab Cleanroom
- The Center for Terahertz Science and Technology Eindhoven (CTSTe)
- Exchange opportunities at TU Darmstadts THz Lab
We Offer
- A 4-year dual PhD degree with TU/e and TU Darmstadt.
- Mentorship from leading experts in photonics and terahertz technology.
- Training in semiconductor growth nanofabrication and advanced photonics.
- A supportive inclusive team passionate about science and societal impact.
Job Requirements
- A masters degree (or an equivalent university degree)in Electrical Engineering or Physics. The first master or diploma degree shall not be older than four years.
- A research-oriented attitude.
- Ability to work in an interdisciplinary team and interested in collaborating with industrial partners.
- Motivated to develop your teaching skills and coach students.
- Fluent in spoken and written English (C1 level).
The applicant shall have knowledge/experience in at least one of the following topics:
- Semiconductors
- Experience with lasers and fiber optics
