Figure 4. Raman spectral scan presented over a range of 50-450 cm-1, of the as-deposited WS2xSe2-2x. films.
Figure 5. Elemental XPS scans of (a) W 4f, (b) Se 3d and (c) S 2p for all as-deposited WS2xSe2-2x films deposited from precursors (1)–(4). (d) Composition of all the as-deposited films deposited from precursors (1)–(4).
Figure 6. (a) Temperature-dependent electrical conductivity, (b) Arrhenius plot for WS2xSe2-2x films deposited from precursors (1)-(4). (c) Electrical conductivity and (d) Hall measurements against the chalcogenide content of the films.
