a Map of general temperature increment above the room temperature (ΔT) for L = 10 nm. b Average temperature increment of the VSe2 layer (ΔTav) of different thicknesses. c Temperature difference between two interfaces of the VSe2 layer (ΔTint) of different thicknesses. d Average (solid) and interface temperature difference (dashed) of the 10 nm-thick layer (ΔTav) with an air gap between VSe2 and sapphire of different thicknesses. The dashed lines are the corresponding temperature difference between top and bottom surfaces of the nanosheet.
