Influence of Dithiocarbamate Cross-Linking Ligands on CdSe Quantum Dot Film ConductivityPublic Deposited
Cadmium selenide (CdSe) quantum dots have low conductivity upon synthesis with the original capping ligands. The conductivity can be altered by the addition of other ligands. Thiols, amines, and carboxylic acids, as well as other functional groups, have been shown to improve conductivity in quantum dot films. This investigation describes the synthesis of alternate dithiocarbamate cross-linking ligands and determines their ability to either improve or inhibit the conductivity of CdSe quantum dot films.
