Improved heat dissipation in gallium nitride light-emitting diodes with embedded graphene oxide pattern
The future of solid-state lighting relies on how the performance parameters will be improved further for developing high-brightness light-emitting diodes. Eventually, heat removal is becoming a crucial issue because the requirement of high brightness necessitates highoperating current densities that would trigger more joule heating. Here we demonstrate that the embedded graphene oxide in a gallium nitride light-emitting diode alleviates the selfheating issues by virtue of its heat-spreadingdoi:10.1038/ncomms2448 pmid:23385596 fatcat:zmszbxcaqjejlayiosnlotll5a
