Expérimental Description
Although nitride LEDs are extremely efficient at low indium content (for blue emission) and low current densities, they suffer from drastic drops in efficiency when going out of theses regimes, partly due to an increase of Auger-Meitner processes. The aim of the proposed internship is to quantify Auger-Meitner processes in in operando nitride LEDs, using electro-emission microscopy. In particular, the role of the device microscopic structure will be investigated.
