DOI: 10.1002/adma.202207841
Abstract: 2D transition metal dichalcogenides are promising platforms for next‐generation electronics and spintronics. The layered Weyl semimetal (W,Mo)Te2 series features structural phase transition, nonsaturated magnetoresistance, superconductivity, and exotic topological physics. However, the superconducting critical temperature of… read more here.
