Alloying n-type (Bi 2 Se 3 and Bi 2 Te 3) and p-type (Sb 2 Te 3) materials is a possible way to obtain a charge compensation and reduce the overall bulk carrier density. While this type of approaches have been extensively studied for bulk and thin film materials 15 – 17 almost no work has been dedicated to colloidally synthesized materials.
