Field-resolved hierarchy of superconducting energy gaps in PdTe
Low-temperature point-contact spectroscopy revealed two distinct superconducting energy scales (0.5 and 1.1 meV) in PdTe, both suppressed by temperature toward the transition temperature Tc. Crucially, these two scales show different responses to magnetic fields, with one scale disappearing near 4.5 kG and the other near 7.5 kG, establishing a field-resolved hierarchy that cannot be described by a single superconducting scale.
