(a) Schematics of the locally distorted DOS. The red dashed line corresponds to DOS of pure bulk PbTe; and denote the Fermi level and the peak position, respectively. (b) Schematics of spherical nanoinclusions embedded in a bulk host; and represent the nanoinclusions average potential height and radius, respectively.

Power factor and the figure of merit as a function of the [(a) and (d)] peak aspect ratio, [(b) and (e)] potential barrier height, and [(c) and (f)] inclusions radii for different positions of the peak relative to the Fermi level, at . The dashed lines correspond to the case when no inclusions are present.
