Here, we report hot-injection colloidal synthesis, characterization, and control of electronic conductivity of nickel-alloyed iron sulfide (Ni x Fe 1−x S 2 ) pyrite nanocrystals (NCs). The Ni-alloyed iron pyrite NCs were synthesized using iron (Fe) and nickel (Ni) bromides as Fe and Ni sources, and...
