Engineering QUAntum materials for TErahertz applications

Project description

The power of quantum materials for THz technology

Despite its potential for revolutionising technology, the terahertz (THz) range remains underdeveloped. Current THz components rely on conventional materials like semiconductors and metals but have yet to deliver the necessary breakthrough. Although recent efforts with two-dimensional materials have shown promise, they still fall short. The key to unlocking the potential of THz technology lies in the ultrafast thermodynamic properties of quantum materials. The ERC-funded EQUATE project aims to harness these properties using materials like graphene and topological insulators. By focusing on thermodynamic principles, the project will develop THz emitters, convertors, and detectors that are faster, more efficient, and capable of advancing THz technology for real-world applications.

Objective

I propose to demonstrate a novel design paradigm for terahertz (THz) technologies, which places the ultrafast thermodynamic properties of quantum materials at the heart. Approaches with conventional semiconductors and metals, as well as recent attempts with two-dimensional materials, typically aim to exploit the optoelectronic properties of materials towards developing THz components and systems. This has so far not led to the desired breakthrough that the, currently still underdeveloped, terahertz regime so greatly needs. The vision of this project is that the truly game-changing potential of quantum materials for THz applications lies in their exceptional ultrafast thermodynamic properties: Quantum materials, such as graphene and topological insulators, have giant thermodynamic THz nonlinearities, and generate ultrafast and efficient THz-induced thermoelectric photocurrents. They can be combined with photonic structures into quantum metamaterials with strongly enhanced light-matter interaction, and are compatible with established electronic and photonic technologies. Exploiting these and more remarkable properties, we will demonstrate THz emitters, nonlinear THz convertors, and THz detectors - all based primarily on thermodynamic design principles. These will outperform currently available THz components on several fronts, and establish quantum materials as the ideal material platform for integrated THz photonics with novel capabilities. Specifically, we will focus on a combination of quantum materials that are relatively well understood, and novel material systems that are promising yet less well understood. As a result, we expect major impacts both on a fundamental level in terms of understanding ultrafast thermodynamic phenomena, and on an applied level in terms of engineering these thermodynamic properties towards concrete THz technologies. The ultimate goal is to unlock the full potential of the THz range and bring utility and benefit to society.
