Enhanced injection efficiency and light output in bottom tunnel-junction light-emitting diodes using UID GaN spacers
Shyam Bharadwaj, Jeffrey Miller, Kevin Lee +6
Recently, the use of bottom-TJ geometry in LEDs, which achieves N-polar-like alignment of polarization fields in conventional metal-polar orientations, has enabled enhancements in…
Blue (In,Ga)N Light-Emitting Diodes with Buried n+-p+ Tunnel Junctions by Plasma-Assisted Molecular Beam Epitaxy
YongJin Cho, Shyam Bharadwaj, Zongyang Hu +4
Blue light-emitting diodes (LEDs) consisting of a buried n+-p+ GaN tunnel junction, (In,Ga)N multiple quantum wells (MQWs) and a n+-GaN top layer are grown on single-crystal Ga-pol…
Polarization control in Nitride Quantum Well Light Emitters Enabled by Bottom Tunnel-junctions
Henryk Turski, Shyam Bharadwaj, Huili +2
The frozen internal polarization-induced electric fields due to broken inversion symmetry in all conventional blue and green nitride semiconductor light emitting semiconductor quan…
