Continuous progress in fabrication techniques for arrays of semiconductor quantum dots
resulted in significant achievements both in understanding the physical processes in quasi
zero-dimensional structures and in their applications. 1, 2 Until recently, most of the
applications envisioned for quantum dot arrays were in the area of optoelectronics. 2–4 The
situation has changed with several most recent proposals of utilization of quantum-dot
superlattices QDSs for thermoelectrics applications. 5–7 Randomly distributed Ge quantum …
