Historically, the transfer of ideas and concepts between optics and condensed-matter physics has been flourishing. Inspired by shaping the scattering of electromagnetic waves by dielectric nanoparticle clusters through the interference of excited multipole modes, we address shaping the scattering of matter waves by quantum dot clusters embedded in a host semiconductor through the interference of excited partial waves. We theoretically demonstrate nearly complete suppression of backward, forward, and both backward and forward scattering, i.e., three versions of the generalized Kerker scattering of matter waves. We envisage that thermoelectric properties of semiconductors can be improved by incorporation of quantum dot clusters exhibiting ultradirectional forward scattering: Such clusters act as phonon-blocking/electron-transmitting inclusions.
