A method for forming efficient, ultrathin GaN light‐emitting diodes (LEDs) and for their assembly onto foreign substances is reported. The LEDs have lateral dimensions ranging from ∼1 mm × 1 mm to ∼25 μm × 25 μm. Quantitative experimental and theoretical studies show the benefits of small device geometry on thermal management, for both continuous and pulsed‐mode operation, the latter of which suggests the potential use of these technologies in bio‐integrated contexts.
