Presentation Title：
Closing the THz gap with layered crystals
Abstract：
The terahertz (THz) frequency range remains challenging for practical devices due to the limited performance of conventional electronic and photonic technologies. This presentation focuses on device-oriented approaches to closing the THz gap using layered crystals and van der Waals heterostructures. THz detectors utilizing plasmonic rectification and interfacial transport phenomena in low-dimensional materials are introduced. By engineering device geometry, gate asymmetry, and heterostructure interfaces, enhanced responsivity and low-power operation at room temperature are achieved. These results demonstrate the potential of layered-crystal-based devices as a platform for next-generation THz sensing and communication technologies.
