Reduced nonthermal rollover of wide-well GaInN light-emitting diodes
Markus Maier, Klaus Kohler, Michael Kunzer, Wilfried Pletschen, and Joachim Wagner
Nonthermal rollover (or efficiency droop) of the electroluminescence (EL) efficiency has been investigated for near-UV-emitting (AlGaIn)N single-well light-emitting diodes (LED) with varying GaInN well widths grown on substrates with different dislocation densities (DDs). For each DD the well width ... [Appl. Phys. Lett. 94, 041103 (2009)] published Mon Jan 26, 2009.
