Abstract
DUV LEDs possess very huge heating issue. On one hand, the sapphire substrate has a poor thermal conductivity, and on the other hand, DUV photons are easily absorbed by the absorptive p-GaN layer and the metal contact in the way of free carrier absorption, which further increases the self-heating effect for DUV LEDs. This chapter briefs readers on the currently adopted technologies for better thermal management.
