Activities and Findings

• Synthesized the first perfectly ordered crystal lattice of semiconductor quantum dots, In2Te3 (trien).

• Discovered and characterized a number of low band gap hybrid semiconductors based on III-VI and V-VI binary and I-III-VI and I-V-VI ternary compounds that are potentially useful for photovoltaic and thermoelectric applications.

• Continued to modify and optimize the structure and composition of M2Q2(ba) type double-layer hybrid structures to enhance their white light emission properties.

Top: Construction of small band gap In2Te3 quantum dots (~1.2 nm) in solid state. We demonstrate here the first perfectly ordered semiconductor QD crystal lattice. Bottom-Left: Optical absorption spectra of the parent structure In2Te3 and the hybrid In2Te3(L). A blue shift of ~1.8 eV is observed. Bottom-Right: Largely enhanced quantum efficiency of white light emission of hybrid[Zn2S2-2xSe2x(ba)] systems.
