Exploring Superconductivity in Misfit Nanodevices — •Sushmita Chandra and Claudia Felser — Nöthnitzer Str. 40, 01187 Dresden

Recently, MISFIT layered compounds (MLCs) have attracted considerable attention in the field of 2D materials due to their unique structure, crystallographic diversity, and chemical tunability. Typically, MLCs can be represented by the general formula [(MX)(1+δ)]m[(TX2)n] with m, n = 1, 2, 3, where M = Sn, Sb, Pb, Bi, rare-earth elements; T = Ta, Nb, Mo, etc., and X = S, Se, Te. The lattice mismatch between the distorted rock salt MX layers and hexagonal TX2 counterparts creates a strained interface in the MLCs which allows a charge transfer from one layer to another, leading to a wealth of fascinating physical phenomena and modulations in the electronic structure. Although MLCs have been extensively studied for their potential applications in thermoelectrics, the fabrication of nanodevices with single- or multilayer MISFIT crystals is a challenging task and has not been explored at all. In this talk, I will present the fabrication of nanodevices based on high-quality MISFIT single crystals. I will also correlate how the misfit strain is associated with the superconducting transition and affects the electronic transport in these natural van der Waals heterostructures.
