Chen, Wei (author), Chen, Ye (author), Cao, Yixing (author), Cui, Z. (author), Fan, Xuejun (author), Zhang, Kouchi (author), Fan, J. (author)In a light-emitting diode (LED) package, silicone encapsulant serves as a chip protector and enables the light to transmit, since it exhibits the advantages of high light transmittance, high refractive index, and high thermal stability. However, its reliability is still challenged under harsh operation conditions. In this study, the optical...journal article 2022

(author), Van Huis, M.A. (author)Here, we show a novel solid?solid?vapor (SSV) growth mechanism whereby epitaxial growth of heterogeneous semiconductor nanowires takes place by evaporation-induced cation exchange. During heating of PbSe-CdSe nanodumbbells inside a transmission electron microscope (TEM), we observed that PbSe nanocrystals grew epitaxially at the expense of CdSe...journal article 2014
