Fig. 2: Thermal and mechanical properties of TiS₃ nanoribbons.

The measured thermal conductivities κ of TiS₃ nanoribbons along b-axis versus temperature T for samples with different thicknesses (a) and lengths (c). The thickness-dependent room temperature thermal conductivity (b) and Young’s modulus (e). The star in (b) means the bulk thermal conductivity from the previous report²⁷. d Schematic diagram of three-point bending scheme for the measurement of Young’s modulus. f The measured force–deflection (F–D) curve during the extension and retraction phase. Young’s modulus can be extracted by fitting the F–D curve. The error bars in thermal conductivity represent uncertainties evaluated based on measurement errors in thermal conductance, nanowire cross-section and length (see Supplementary Note 6). The error bars in Young’s modulus represent uncertainties calculated based on measurement errors in the AFM cantilever spring constant, nanowire cross-section and length determined as the standard deviation from three individual measurements.
