2020年12月2日 · Here, by carrying out synchrotron- and laser-based angle-resolved photoemission spectroscopy, we systematically investigated the electronic structure of a quasi-one-dimensional superconductor TaSe3 and identified the non-trivial topological surface states.

2024年12月19日 · Here, we reported a quasi-one-dimensional (quasi-1D) van der Waals (vdW) TaSe 3 crystal as a promising material candidate for PTE detection. Benefiting from the 1D confined effect for photon and electron transport, the TaSe 3 nanoribbon crystallized along the atomic chain direction demonstrates a size-dependent thermal conductivity and Seebeck ...

2021年1月6日 · Combined with the electronic transport and STS results, TaSe 3 was experimentally demonstrated as an ideal candidate for TSC, providing an ideal platform for realizing MBSs. In summary, the present study by Chen at al. systematically unveiled the inverted band gap and in-gap TSSs in quasi-1D superconductor TaSe 3 , holding promise for the study ...

2021年5月20日 · Here we use angle-resolved photoemission spectroscopy and spin- and angle-resolved photoemission spectroscopy to visualize the strain-driven band-structure evolution of the quasi-one-dimensional...

Here, by carrying out synchrotron- and laser-based angle-resolved photoemission spectroscopy, we systematically investigated the electronic struc-ture of a quasi-one-dimensional superconductor TaSe3 and identi-fied the non-trivial topological surface states.

1D TaSe3 exhibits many unusual physical properties due to its distorted type‐II chains. Ribbon‐shaped single crystals can be easily bended along the b‐axis, forming rings.

2024年3月21日 · The (TaSe 4) 2 I photodetector exhibits excellent polarization-sensitive photodetection, with a high dichroic ratio of I max /I min = 2.32 under 637 nm illumination. Notably, the (TaSe 4 ) 2 I nanowire photodetector exhibits a competitive performance in uncooled mid-wave infrared (MWIR) detection with a high photoresponsivity ( R ) of 110.5 AW ...

We report results of investigation of the low-frequency electronic excess noise in quasi-1D nanowires of TaSe 3 capped with quasi-2D h-BN layers. Semimetallic TaSe 3 is a quasi-1D van der Waals material with exceptionally high breakdown current density.

Here, by carrying out synchrotron- and laser-based angle-resolved photoemission spectroscopy, we systematically investigated the electronic structure of a quasi-one-dimensional superconductor TaSe 3 and identified the non-trivial topological surface states.
