Schematic of the structural relationship among groups IV, II-VI, , and semiconductor materials.
Comparison between experimental and theoretical size dependent optical band gap for nanocrystals. Experimental data (open circles) are from Refs. 33 and 34.
Calculated size dependent optical band gaps for , , , and nanocrystals.
Calculated size dependent optical band gaps for , , and nanocrystals.
Variation in optical band gap of chalcopyrite-type semiconductor nanocrystals. The largest and smallest optical band gap for the individual materials are calculated values for the 2 and 5 nm sized nanocrystals, respectively.
Energy band gap of bulk materials , effective mass of electron and hole, and , respectively, and confining potential of electron and hole for various ternary chalcopyrite-type semiconductors (Ref. 32). The confining potential determined by that the energy gap between the HOMO and LUMO of the surfactant oleylamine is 4.430 eV.
