2018年8月3日 · We show that the CDW system of 1T-TaS 2 is highly sensitive to light directly from visible down to terahertz, with current responsivities on the order of ~1 AW −1 at room temperature. Our findings open a new avenue for realizing uncooled, ultrabroadband, and sensitive photoelectronics continuously down to the terahertz spectral range.

2023年10月18日 · In this work, we investigate the metal-to-insulator phase transition in the transition metal dichalcogenide 1T-TaS 2 embedded in low-energy terahertz (THz) and sub-THz cryogenic cavities...

2021年1月15日 · Here, we experimentally demonstrate localized plasmons in a correlated 2D charge-density-wave (CDW) material: 2H-TaSe 2. The plasmon resonance can cover a broad spectral range from the terahertz...

Tantalum disulfide (TaS2) is a transition metal dichalcogenide (TMD) that exhibits phase transition induced electronic property modulation at low temperature. However, the...

2024年10月16日 · For this purpose, we embed 1T-TaS 2 into THz Fabry–Pérot cryogenic cavities tunable in frequency within the spectral range of the vibrational modes of the insulating phase and track the linear response of the coupled phonons across the insulator-to-metal transition.
