Strain-controlled superconductivity in epitaxially grown thin films of 1T-TaS₂.

ABSTRACT: 1T-TaS₂ is a prototype layered material with a rich phase diagram that includes multiple charge density wave (CDW) transitions and technologically important metastable states. It also supports a superconducting phase induced by hydrostatic pressure, cation substitution, intercalation, or doping. Thin 1T-TaS₂ crystals deposited on various substrates exhibit transition temperatures that are strongly dependent on the substrate-induced strain, and depart from bulk transition temperatures in a way that is not clearly understood at present. Here we show that thin polycrystalline films of 1T-TaS₂ grown by molecular beam epitaxy on (LaAlO₃)_0.3(Sr₂TaAlO₆)_0.7 (LSAT) substrates have a suppressed CDW transition to
