中文摘要
首席研究员将开发实验方法, 测量了选定的绝缘材料的光电导, 半导体矿物然后PI将光电导性 光谱到能级结构,并提取信息, 传输特性,如载流子密度和 激发态的离域。最终,他希望 证明这些光谱的解释价值 矿物的电子和输运性质。
英文摘要
The principal investigator will develop experimental methods for the measurement of photoconductivity of selected insulating and semiconducting minerals. The PI will then relate photoconductivity spectra to energy level structure, and extract information on transport properties such as carrier densities and degree of delocalization of excited states. Ultimately he wishes to demonstrate the value of these spectra for interpretation of electronic and transport properties of minerals.
