Impact of Stoichiometry on the Electronic Structure of PbS Quantum Dots
Although the stoichiometry of bulk lead sulfide (PbS) is exactly 1∶1, that of quantum dots (QDs) can be considerably different from this crystalline limit. Employing first-principles calculations, we show that the impact of PbS QD stoichiometry on the electronic structure can be enormous, suggesting...
