The term quantum dot (QD) solid is used to describe arrays composed of colloidal nanocrystals which embody unique and tunable quantum confinement-induced benefits yet possess long-range electronic transport necessary for device applications. Attention in the past has been focused on removal of native ligands during QD solid formation to enable electronic wavefunctions to overlap between neighboring QDs with use of strongly bound thiols. Recent results show that additional halide ions can enable much greater control over electronic properties of the solid, and thus enable insight into constructing films with desired characteristics. Application of the halides can occur during synthesis, during QD solid formation, or during post processing. Resulting properties of QD solids for high performance optoelectronic device applications will be discussed.
