From: RF injection scanning tunneling spectroscopy of a superconducting NbSe2 surface
(a) STM topographic image of the NbSe2 surface at the ___domain boundary of the 2 H 3 × 3 and 1 T √13 × √13 superstructures. (Vs = − 100 mV, It = 50 pA). (b) Position-dependent variation of the STS results without RF injection. (c) The gap energy at each position at marks 1 − 6 specified in (a).
