项目摘要

9224168 Clark This award is to start a new Materials Research Group at the University of Colorado at Boulder on the topic of ferroelectric liquid crystals. The research is organized in three main activities: synthesis of new materials, fundamental physics of ferroelectric liquid crystals, and modeling of the molecular structure and physical properties. The synthesis activity includes making of new monomer, polymer, and gel ferroelectric liquid crystals to explore the molecular origins of particular property characteristics, to test predictions from the modeling, and to develop new electro-optic and nonlinear optical materials. The physics activity emphasizes evaluation of the relevant physical properties of the materials, structure of the phases, and dynamics of the phase transformations. Included in this activity are x-ray scattering, optical microscopy, time-dependent optical and vibrational spectroscopy, molecular conformational dynamics, dielectric relaxation, scanning tunneling microscopy, and optical reflectivity. The modeling activity includes molecular dynamic simulations of molecular arrangements and conformation, and calculation of measurable macroscopic properties. Ferroelectric liquid crystals offer exceptional capabilities in electro-optic applications, such as electrically operated light valves having microsecond response times, high contrast intrinsic memory, low power consumption displays, and nonlinear optical materials. The materials research group offers excellent educational opportunities for multi- disciplinary training of advanced students for research and teaching.

9224168克拉克这个奖项是为了在科罗拉多大学博尔德分校成立一个新材料研究小组，研究铁电液晶的主题。这项研究分为三个主要活动：新材料的合成，铁电液晶的基础物理，以及分子结构和物理性质的模拟。合成活动包括制造新的单体、聚合物和凝胶铁电液晶，以探索具有特殊性质特征的分子起源，检验从模型中预测的结果，以及开发新的电光和非线性光学材料。物理活动强调对材料的相关物理性质、相结构和相变动力学的评价。包括X射线散射、光学显微镜、含时光学和振动光谱、分子构象动力学、介电弛豫、扫描隧道显微镜和光学反射率。模拟活动包括分子排列和构象的分子动力学模拟，以及可测量的宏观性质的计算。铁电液晶在电光应用中提供了非凡的能力，例如具有微秒响应时间的电动光阀、高对比度本征存储器、低功耗显示器和非线性光学材料。材料研究小组为多学科培养高级学生进行研究和教学提供了极好的教育机会。
