项目摘要
ABSTRACT CTS-9615903 This is a comprehensive analytical and experimental study of microscale heat transfer in porous silicon. Analytical work incorporates size, structure, and surface-area effects into a general microscale heat-transfer framework to predict thermal conductivity, optical properties, and radiative transfer. Established experimental techniques are used to examine these effects and to determine key model parameters. Simple engineering models for energy absorption and transport in porous silicon are developed for use in design of porous-silicon-based optoelectronic devices. There is no extant analytical framework for predicting the combined effect of crystallite size and structural randomness on energy absorption and transport in nanometric-scale random structures. Porous silicon, which has such a structure, can emit visible light in response to optical or electrical stimulation at room temperature offering a prospect of large-scale integration of optics and electronics. Knowledge of the thermophysical properties and energy transport mechanisms is critical for design of porous-silica-based devices like optical switches and light-emitting diodes (LEDs), as well as for the laser processing of these devices.
CTS-9615903是对多孔硅微尺度传热的综合分析和实验研究。分析工作将尺寸、结构和表面积效应纳入一般的微尺度传热框架,以预测导热性、光学性质和辐射传递。已建立的实验技术用于检验这些影响并确定关键模型参数。建立了多孔硅中能量吸收和输运的简单工程模型,用于多孔硅基光电器件的设计。在纳米尺度的随机结构中,晶体尺寸和结构随机性对能量吸收和输运的综合影响还没有现成的分析框架。多孔硅具有这样的结构,在室温下,在光或电刺激下可以发出可见光,为光学和电子的大规模集成提供了前景。热物理性质和能量传输机制的知识对于多孔硅基器件的设计至关重要,如光开关和发光二极管(led),以及这些器件的激光加工。
