9806055 Hirschmugl This project focuses on unraveling energy decay pathways for adsorbate vibrations and studying low energy dynamics during growth of wide band gap materials. Far infrared reflection absorption spectroscopy (Far-IRAS) of molecules adsorbed at ionic surfaces will be utilized to directly measure vibrational lineshapes. Real-time Far-IRAS measurements during in-situ growth of thin oxide films on metallic and insulating substrates is also included in the study. Frequency-dependent conductivity and lattice vibrations will be measured, providing electronic and morphological information simultaneously. The infrared measurements will be augmented by conventional surface analytical techniques, including LEED, RHEED, AES, and TPD. %%% This is a research enhancement grant made under the Professional Opportunities for Women in Research and Education (POWRE) program. The research will contribute new materials science knowledge at a fundamental level.

9806055 Hirschmugl该项目的重点是解开吸附物振动的能量衰减途径，并研究宽带隙材料生长过程中的低能动力学。吸附在离子表面的分子的远红外反射吸收光谱（Far-IRAS）将被用来直接测量振动线型。实时远红外光谱测量过程中的金属和绝缘基板上的氧化物薄膜的原位生长也包括在研究中。频率依赖的电导率和晶格振动将被测量，同时提供电子和形态信息。红外测量将通过传统的表面分析技术，包括LEED，RHEED，AES和TPD来增强。 这是根据研究和教育领域女性专业机会（POWRE）方案提供的研究增强补助金。这项研究将在基础层面上贡献新的材料科学知识。
