Web20 de jan. de 2024 · Layered metallic transition-metal dichalcogenides (TMDCs) are ideal platforms for exploring their fascinating electronic properties at two-dimensional limits, such as their charge density wave (CDW) and superconductivity. Therefore, developing ways to improve the crystallization quality of TMDCs is urgently needed. Here we report … Web1 de nov. de 2024 · This work presents a systematic study of the physical properties of Te deficient samples of the two-dimensional conductor NiTe 2. X-ray diffraction data shows that Ti can be intercalated in Te-Te Van der Waals gaps and consequently a superconductor state emerges in the vicinity of 4 K that is insensitive to pressure.

WebHá 1 dia · 1.Introduction. The idea underlying low-dimensional thermoelectrics is to reduce one or two dimensions of a bulk material to below the spatial extent of pertinent electron wavefunctions, pursuing discrete or non-dispersive electronic states with enhanced density of states near the Fermi level (E F).As a consequence, quantum confinement of electron … Webmirror symmetry, a supersymmetric duality between certain pairs of 2+1-dimensional theories. We show that the half- lled zeroth Landau level of a pair of Dirac fermions is dual to a pair of Fermi surfaces of electrically-neutral composite fermions, coupled to an emergent gauge eld. Thus, we use supersymmetry to provide a derivation of

WebHere, we report on the observation of 2D superconductivity in electron gases formed at oxide-insulator/KTO (111) interfaces. We have measured Tc as high as 2.2 K, and this value can be tuned by varying carrier density during the sample growth. We also observe an emergent stripe phase, which breaks the rotational symmetry in the KTO (111) surface.
