Structures and Dynamics of Solids Under High Pressures and other Extreme Conditions

使用拉曼光谱和x射线衍射等技术，将研究高压和其他极端条件下凝聚态系统的结构、动力学、相变、化学反应和电子性质。要研究的系统包括：氧、氮和硫的相平衡，以及氧/氮、一氧化碳/氮、氧/氩的混合物；有机和高分子导电材料的结构；简单芳香分子在中压下的热和光不稳定性。此外，将开发用于高压x射线衍射研究的内部加热金刚石砧细胞。

The structure, dynamics, phase transitions, chemical reactions and electronic properties of condensed systems at high pressures and other extreme conditions will be investigated using techniques such as Raman spectroscopy and x-ray diffraction. Systems to be investigated include: phase equilibria of oxygen, nitrogen and sulfur, and mixtures of oxygen/nitrogen, carbon monoxide/nitrogen, oxygen/argon; structures of organic and polymeric conducting materials; thermal- and photo-instabilities of simple aromatic molecules at moderate pressures. In addition, internally heated diamond-anvil cells for x-ray diffraction studies at high pressures will be developed.
