Controlling superconducting phase transition on a two-dimensional (2D) material is of great fundamental and technological interest from the viewpoint of making 2D resistance-free electronic circuits. <>>> Please reconnect. The MZMs survive up to a critical doping of the TI at which there is a vortex phase transition that eliminates the MZMs. Superconducting simulators are used to investigate dynamical phase transitions, revealing their applications in quantum metrology.

Here, we demonstrate that a 1T-to-2H phase transition can be induced on the topmost monolayer of bulk (<100 nm thick) 1T-TaS2 by thermal annealing. Scalable Production of Two-Dimensional Metallic Transition Metal Dichalcogenide Nanosheet Powders Using NaCl Templates toward Electrocatalytic Applications. Here, we demonstrate that a 1 T -to-2 H phase transition can be induced on the topmost monolayer of bulk (<100 nm thick) 1 T -TaS 2 by thermal annealing.

Liu, Z. Duan, C. Zhang, X. X. Hu, J. All rights reserved. Scanning tunneling microscopy measurements reveal a 3 × 3 charge density wave (CDW) in the phase-switched monolayer at 4.5 K. The enhanced Tc is explained by the suppressed 3 × 3 CDW and a charge-transfer doping from the 1T substrate. VPT spectrum versus μ for (a) a TI with vortex line parallel to z, (b) a HOTI with a vortex line parallel to z, (c) a HOTI with a vortex line parallel to x. We find that the surface transition appears because of the competition between the superconducting gap and the local T-breaking gap on the surface. without permission from the American Chemical Society.

Single-water-dipole-layer-driven Reversible Charge Order Transition in 1T-TaS2. Users are Use of the American Physical Society websites and journals implies that Conditions and any applicable The observed surface-limited superconducting phase transition offers a convenient way to prepare robust 2D superconductivity on bulk 1T-TaS2 crystal, thereby bypassing the need to exfoliate monolayer samples. In particular, we find two distinct features. 2 ©2020 American Physical Society. (a) schematic picture shows the distance between a vortex (red dot) from hinge dh and center dc of lattice (black dot), (b) μc,2 versus dh for HOTI with superconducting vortex along the x direction (HOTI x) with two system sizes of N=24, 28 and HOTI z and TI with N=28.

We further show that the monolayer 2H-TaS2 could be switched back to 1T phase by applying a voltage pulse. 2 <> Find more information about Crossref citation counts. The second transition is the well-known vortex phase transition. the Altmetric Attention Score and how the score is calculated. system. In this work, we show that the phenomenology in higher-order topological insulators (HOTIs) can be qualitatively distinct.
