Fig. 1: Kondo effect within a MoS2 MTB.
From: Modulated Kondo screening along magnetic mirror twin boundaries in monolayer MoS2
a, Kondo coupling of graphene (bath) with the non-degenerate states (impurity) confined along a MoS2 MTB. Fermi energy EF and Coulomb energy U are indicated (see the main text). The electron inside the highest occupied state is symbolized by an arrow. b, Atomically resolved topography of a single-layer MoS2 island on graphene, with two MTBs of lengths 7.1 nm (left) and 9.0 nm (right), separating mirror-symmetric domains. c,e, Spatially averaged dI/dV spectra along an MTB of 8.6 nm before (c) and after (e) voltage pulses applied with the STM, being in a state that is either degenerate (c) or non-degenerate (e). d,f, Conductance colour maps showing spatially resolved dI/dV spectra along the MTB. The dashed white lines are added to highlight the phase relation between the states on either side of EF in the middle of the boundary. STM/STS parameters: for b, 20 × 20 nm2, Vset = 500.0 mV, Iset = 10 pA; for c and d, Vset = 500.0 mV, Iset = 1.0 nA; for e and f, Vset = 500.0 mV, Iset = 0.5 nA; Vmod = 2.5 mV.
