建立了一个分析模型，用于研究具有超薄几何形状和布局的微尺度无机发光二极管（mu-ILED）的热特性。预测的表面温度和μ-ε温度与实验和有限元模拟吻合良好。一个简单的标度律得到的归一化μ-ε温度与归一化μ-ε尺寸。这项研究提供了一个理论，以指导布局的设计，最大限度地减少不利的热效应的性能mu-ILED不仅为固态照明，但也为应用程序集成mu-ILED设备上复杂/软基板，目前感兴趣的光遗传学和其他新兴领域的生物学。
An analytical model is developed to study the thermal properties of microscale, inorganic light-emitting diodes (mu-ILEDs) with ultra-thin geometries and layouts. The predicted surface and mu-ILED temperatures agree well with experiments and finite-element simulations. A simple scaling law is obtained for the normalized mu-ILED temperature versus the normalized mu-ILED size. This study provides a theory to guide the design of layouts that minimize adverse thermal effects on the performance of mu-ILEDs not only for solid-state lighting but also for applications integrating mu-ILED devices on complex/soft substrate as are currently of interest in optogenetics and other emerging areas in biology.
