| BKT like transition of 1-UC FeSe films. (a) The V ( I ) curves at different temperatures, the two dashed lines correspond to V ∼ I and V ∼ I 3. (b) The power-law exponent α ( V ∼ I α ) as a function of temperature, with α = 3 ( T ∼ 23.1 K) indicating BKT transition. (c) The R ( T ) curve plotted on a [d ln( R )/d T ]− 2/3 scale. The dashed line is the behavior expected for a BKT transition with T BKT = 23.0 K.[ 23 ] |
