Figure 3: Temperature-dependent thermal conductivity of BP nanoribbons.

From: Anisotropic in-plane thermal conductivity of black phosphorus nanoribbons at temperatures higher than 100 K

Figure 3

(a) Thermal conductivity (κ) versus temperature (T) plot of BP nanoribbons axially oriented to the ZZ and AC directions, respectively. Thickness (t)/width (W) of the ZZ and AC nanoribbons are 170/540 nm and 170/590 nm, respectively. Error bars include the errors (∼8%) from thermal conductance and sample size measurements. (b) κ versus T plots (on logarithmic scale) of ZZ nanoribbons with different dimensions; 170 (t)/540 nm (W) and 310 (t)/540 nm nm (W). (c) κ versus T plots (on logarithmic scale) of AC nanoribbons with different dimensions; 170 (t)/590 nm (W) and 270 (t)/420 nm (W). The solid lines in b and c are fitted lines by taking into account various phonon scattering mechanisms (phonon–phonon, impurity and boundary). Lengths of the nanoribbons all exceed 10 μm.
