Mapping of the electrostatic potentials in MOCVD and hybrid GaN tunnel junctions for InGaN/GaN blue emitting light emitting diodes by off-axis electron holography correlated with structural, chemical, and optoelectronic characterization

Cooper, D. Fan Arcara, V. Damilano, B.

Off-axis electron holography has been used to measure the width of the depletion region in a series of Tunnel Junction GaN light emitting diodes that have been prepared using different growth processes for blue emission. The total measured potentials are combinations of the mean inner potential, dopant potential and piezoelectric contributions....

Multi-microscopy nanoscale characterization of the doping profile in a hybrid Mg/Ge-doped tunnel junction

Di Russo, E. Mavel, A. Fan Arcara, V

A multi-microscopy investigation of a GaN tunnel junction (TJ) grown on an InGaN-based light emitting diode (LED) has been performed. The TJ consists of a heavily Ge-doped n-type GaN layer grown by ammonia-based molecular-beam epitaxy on a heavily Mg p-type GaN thin layer, grown by metalorganic vapor phase epitaxy. A correlation of atom probe...
