CsV3Sb5
¶
Electronic Properties¶
- Onset of Superconductivity for
with , continuously suppressed by MF. - The kink behavior in the
variation (AV3Sb5 general properties) around 94K is related to long range CDW order. The sharp peak in heat capacity indicates the CDW transition is First order phase transition phase transition - This weakly first order transition is best characterized in
Topological Properties¶
- The normal state of
is a topological metal, and this topological property leads to a surface state embedding around the bulk FS at the M point
