We merge Terahertz and Nanotechnology to enable next-generation solutions for advanced applications
THzNanoVision’s novel Terahertz (THz) devices can be broadly applied in the fields of telecommunications, non-destructive material testing, and drug and food inspection. These application areas can be further extended to biomedical and security engineering. The unique value of our THz technology lies in its clear differentiation from hazardous alternatives such as X-ray and UV technologies, as it is biocompatible and safe for human health.
Founder
Dr.-Ing. Ahid S. Hajo is the founder of the THzNanoVision. He has worked in the field of terahertz and nanotechnology for new THz sources and detectors as a part of his doctorate at the department of Photonics and Optical Communications at the Institute of Microwave Engineering and Photonics (IMP), Technical University of Darmstadt and of his master in Physics at the department of the Ultrafast Spectroscopy and Terahertz Physics at the Institute of Physics (PI), Goethe University Frankfurt. After his master, he worked as an Early-Stage Researcher (ESR) at the PI and then at the IMP. In Oktober 2020, he joined the department of the Terahertz Devices and Systems Laboratory, where he is currently working as a group leader. His current research interests include the field of nanowire based THz Schottky detectors, GaN based THz Gunn sources, anda CNT based THz detectors and sources for non-destructive security and telecommunication as well as biomedical applications. He has authored and coauthored more than 25 journal articles and published conference contributions as well as three patents.

Sajed Rezaei is working on the characterization of terahertz Gunn sources. In January 2024, he received his bachelor's degree in Mechatronics. Since April 2024, he is a master‘s student and working at TU Darmstadt and Hochschule Darmstadt as a HiWi as well as he was involved in several projects include the design and implementation in automatic control, academic research, computer-aided design, programming, simulations, and R&D.
Mentors
Prof. Dr. Claus von Campenhausen is a financial expert with distinguished positions in corporate finance (Siemens, New York) and banking (Crédit Agricole Investment Bank, Frankfurt/Paris) and is now at Macromedia University of Applied Sciences. He studied at the University of Bonn, the Vienna University of Economics and Business (Magister), and the London School of Economics (MSc in Accounting and Finance). He earned his doctorate at the University of St. Gallen with a dissertation entitled “Option Valuation under Stochastic Volatility: Theory and Empirical Evidence.” Afterwards, Campenhausen initially worked for a strategy consultancy in Western Europe, then for Siemens in New York, and subsequently moved to the French major bank Crédit Agricole Investment Bank in Frankfurt. In parallel, Prof. von Campenhausen taught finance-related subjects at various universities. He is currently Professor of Business Administration and Management at Macromedia University of Applied Sciences and, among other roles, serves as Chairman of the Supervisory Board of an asset management company and is involved in various startup initiatives.
Prof. Dr. Sascha Preu is one of the two mentors of THzNanoVision. He received the Diploma and Ph.D. degrees in physics from Friedrich-Alexander Universität Erlangen-Nürnberg, Erlangen, Germany, in 2005 and 2009, respectively. From 2004 to 2010, he was with the Max Planck Institute for the Science of Light, Erlangen. From 2010 to 2011, he was with the Department of Materials and Physics, University of California at Santa Barbara, CA, USA. From 2011 to 2014, he worked as the Chair of applied physics with Universität Erlangen-Nürnberg. In 2017, he received the ERC Starting Grant for developing ultra-broadband and photonic terahertz signal analyzers. In 2022, he received an ERC Proof of Concept grant focusing on pre-commercial prototypes of photonic spectrum analyzers. He is currently a Full Professor with the Department of Electrical Engineering and Information Technology, Technical University of Darmstadt, Germany, leading the Terahertz Devices and Systems Laboratory.
Advisory Board
