An analytical model is developed to study the thermal properties of microscale, inorganic light-emitting diodes (m-ILEDs) with ultra-thin geometries and layouts. The predicted surface and m-ILED temperatures agree well with experiments and finite-element simulations. A simple scaling law is obtained for the normalized m-ILED temperature versus the normalized m-ILED size. This study provides a theory to guide the design of layouts that minimize adverse thermal effects on the performance of
