MRI: Femtosecond Laser Facility for Microscale Heat Transfer Research

抽象格里戈罗普洛斯 基金被授予购买飞秒激光器。 该激光器将用于研究金属、半导体、绝缘体和液体中的超短能量转移。 这项工作将集中在理解和量化的激光能量耦合到被照射的目标材料。 这需要适当考虑能量传递的微观机制，而这些机制在平衡假设下的连续介质传热框架中无法提供。 此外，飞秒激光将用于研究电子从金属和半导体表面解吸的机制。 这一主题对许多应用特别重要，包括从敏感的微电子和微机电（MEMS）器件表面去除残留水分。

Abstract Grigoropoulos Funds are awarded to purchase a femtosecond laser. This laser will be used to investigate ultra-short energy transfer in metals, semiconductors, insulators, and liquids. The work will be focussed on the understanding and quantification of the laser energy coupling to the irradiated target material. This requires proper account of the microscopic mechanisms of energy transfer that cannot be provided in the continuum heat transfer framework under the equilibrium assumptions. In addition, the femtosecond laser will be used to study the mechanisms of electronic desorption from metal and semiconductor surfaces. This topic is of particular importance to many applications, including the removal of residual moisture from sensitive micro-electronics and micro-electro-mechanical (MEMS) device surfaces.
