Figure 4From: Effect of grain size on thermal transport in post-annealed antimony telluride thin films Total and lattice thermal conductivities of the films at 300 K. (a) Measured cross-plane (κf) and (b) lattice thermal conductivity (κL) of 400-nm-thick Sb2Te3 thin films at 300 K with different annealing temperatures of up to 350°C. (c) Measured lattice thermal conductivity of films as a function of grain size at 300 K. Dotted lines represent the best fitting.Back to article page
