High‐mobility suspended MoS2 devices with tunable threshold voltage

InfoMat, EarlyView.
Due to their atomic‐scale thickness, two‐dimensional materials (2DMs) are highly sensitive to their environment, including the substrate. By fabricating various suspended molybdenum disulfide devices, this study demonstrates that the suspended structure can shield the influence of the substrate on the properties of 2DMs, thereby enabling better ...

Topological Photonic Devices and Circuits at Terahertz Frequencies

Laser &Photonics Reviews, EarlyView.
This review examines how 3D topological insulators and emerging topological photonic phases enable robust, low‐loss and defect‐immune terahertz devices. Fundamental properties, device implementations and topological transport mechanisms are surveyed, revealing new opportunities for reconfigurable, high‐performance THz components and scalable ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, EarlyView.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Room Temperature Evidence of PtTe2 Topological Semimetal Character

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
We report on a melt growth process for the synthesis of high‐quality PtTe2 crystals, as assessed by X‐ray diffraction and X‐ray photoemission spectroscopy characterization. By angle‐resolved photoemission spectroscopy investigation, we observe the expected topological features at cryogenic temperature and we demonstrate their stability even at room ...
