Quantum metasurface boosts terahertz detection sensitivity by exploiting in-plane photoelectric effect

Being able to see light and detect radiation is of utmost importance at any frequency. While this challenge has been solved in the visible range, radiation detectors in the far-infrared and terahertz regimes are either not sensitive, slow, or require bulky and expensive, often cryogenically cooled devices, which hinders practical applications.
Advances in quantum materials and metasurface design are enabling breakthroughs in traditional detection limitations.
Improved detection capabilities in the terahertz regime unlock applications in medical imaging, security, telecommunications, and industrial sensing, broadening the scope of what can be monitored and analyzed.
The ability to sensitively and affordably detect terahertz radiation moves from theoretical and niche applications to practical, widespread use, overcoming previous size, cost, and cooling constraints.
