(a, b) Time-of-flight secondary ion mass spectrometry depth profile measurements for positive and negative ions, respectively. (c) Schematic description of the deposited multilayer arrangement and cross-section scanning electron microscopy image. (d) Raman spectra of the obtained MoSSe thin film showing the blue-shifted A1 and E1 corresponding to the MoSSe phase. Inset displays a schematic of the A1 and E1 Raman modes of MoSSe with gray balls denoting molybdenum atoms, and orange and yellow selenium and sulfur atoms, respectively.
