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.

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. Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals.

We observe a smooth crossover from the disorder-driven superconductor-normal metal transition (SMT) to the superconductor-insulator transition (SIT) via the intermediate Bose metal state detected by the low-temperature saturation of the temperature dependence of the sheet resistance. The monolayer 2H-TaS2 on bulk 1T-TaS2 exhibits a superconducting transition temperature (Tc) of 2.1 K, which is significantly enhanced compared to that of bulk 2H-TaS2. Information. In particular case of normal – superconducting phase transitions we have shown that (1) the normal and superconducting crystal structures are not identical, (2) the phase transition between them proceeds by a structural rearrangement, (3) the epitaxial version of the nucleation-and-growth is its system.

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. In this work, we show that the phenomenology in higher-order topological insulators (HOTIs) can be qualitatively distinct. In particular case of normal – superconducting phase transitions we have shown that (1) the normal and superconducting crystal structures are not identical, (2) the phase transition between them proceeds by a structuralepitaxial The second transition is the well-known vortex phase transition.

This parameter vanishes at the transition between two topological superconducting phases with opposite Chern numbers, see figure 3(b) . We find that the surface transition appears because of the competition between the superconducting gap and the local T-breaking gap on the surface. Such quantum transition can occur if the magnetic field is tuned such that it suppresses superconductivity in the islands with the weaker critical field, while the islands with stronger energy gap remain superconducting.
