■ Silicon Quantum Dot Polymer ■

The semiconductor quantum dots (QDs) embedded in organic polymer hybrid has been designed to take full advantage of the properties of the constituent materials. Addition, semiconductor QDs polymer materials have improvements in physical and chemical properties, thermal stabilities, well solubility, and tunable mechanical properties. As a promising material, silicon QD polymer (Si QD) has gathered much attention due to Si QD nontoxicity and abundance as well as the ease of integration into well-established industrial silicon processes.
Therefore, our lab recently showed that the synthesis of Si QD-polystyrene nano-composite created by a thermally-initiated one-pot hydrosilylation/polymerization reaction in hydride-terminated Si QDs (H-Si QDs) and styrene monomer. Importantly, in this study, thin films of the nano-composite that exhibited charge trapping properties and memory characteristics were fabricated by using a solution process and low curing temperatures; these conditions are suitable for large-scale and flexible device fabrications

Other lab’s study, we present a new material design concept, silicon quantum dot (Si QD) polymers, for which surface-functionalized Si QDs can be regarded as a large monomer in the polymers. The refractive index of the Si QD-PS polymers was linearly increased as the content of the Si QD in the polymers was increased for the thin films dried at 40^oC and 150^oC.
