Characterization of organically capped Si and group 14 alloy nanoparticle heterojunctions

太阳能转换等应用在设备架构方面面临着限制效率的基本挑战。近年来，无机/有机杂化材料已成为该领域的研究热点。该提案结合了PI在纳米材料合成，结构表征和薄膜中电子传输的物理表征方面的专业知识：Susan Kauzlarich（加州大学戴维斯分校化学）：化学合成和表征；Klaus Meerholz （UCologne，物理化学）：杂化材料的光电特性。本国际化学合作（ICC）提案旨在合成具有空穴导电有机分子的Si和Si1-xGex合金NPs，以研究具有带状电子结构的无机半导体与具有局域电子态的有机半导体之间的电荷传输/转移。

Applications such as solar energy conversion are faced with fundamental challenges in device architecture that limits efficiencies. Recently, inorganic/organic hybrids have entered the focus of research in this field. This proposal combines the PI’s expertise in nanomaterials synthesis, their structural characterization, and physical characterization of electron transport in thin films: Susan Kauzlarich (UC Davis-Chemistry): chemical synthesis and characterization; Klaus Meerholz (UCologne, Physical Chemistry): optoelectronic characterization of hybrid materials. This International Collaboration in Chemistry (ICC) proposal aims to synthesize Si and Si1-xGex alloy NPs with hole conducting organic molecules to study charge transport/transfer between inorganic semiconductors typically exhibiting a band-like electronic structure and organic semiconductors featuring localized electronic states.
