a Raman spectra of 2H-MoS2 sample. b Local phases of 2H-MoS2 at a high resolution TEM image of the unused MoS2 switch sample at 2H [3 4 −1] axis with FFT. The crystal is rotated or twisted along [3 4 −1] axis and two set of diffraction patterns share 2H (1 0 3) diffraction disc (inset). c EDX Ag \(K\alpha\) region spectra acquired from 500 nm by 500 nm regions in the middle of unused and used samples, showing 0.3 at.% difference of Ag concentration. d Atomic resolution HAADF-STEM image and schematic of 2H phase MoS2 crystal structure. e, f Regions with dislocation paths cross the MoS2 at higher magnification (used sample), showing different lattice parameters which may indicate the formation of localised 1T-MoS2 phase.
