Figure 4From: Enhanced thermoelectric performance in three-dimensional superlattice of topological insulator thin filmsOptimized geometric parameters. Optimization of the geometric parameters b, c, and d for the 3D superlattice with a = 3QL at T = 250 K and μ = 60 meV. The geometric parameter dependence of ZT values for 3D superlattice with a = 2QL and 1QL has similar trends as given here for the case of a = 3QL.Back to article page
