Nodeless superconductivity in type-II Dirac semimetal PdTe2: low-temperature London penetration depth and symmetry analysis

Serafim Teknowijoyo, Na Hyun Jo, Mathias S. Scheurer +6

Superconducting gap structure was probed in type-II Dirac semimetal PdTe${}_2$ by measuring the London penetration depth using tunnel diode resonator technique. At low temperatures,…
