Leveraging both faces of polar semiconductor wafers for functional devices
Len van Deurzen, Eungkyun Kim, Naomi Pieczulewski +8
Unlike non-polar semiconductors such as silicon, the broken inversion symmetry of the wide bandgap semiconductor gallium nitride leads to a large electronic polarization along a un…
Influence of GaN substrate miscut on the XRD quantification of plastic relaxation in InGaN
J. Moneta, M. Krysko, J. Z. Domagala +5
Strain relaxation of thick InGaN layers was studied in order to develop technology of InGaN templates for deposition of InGaN Quantum Wells (QWs) and InGaN layers of high-In-conten…
Electrically pumped blue laser diodes with nanoporous bottom cladding
Marta Sawicka, Grzegorz Muziol, Natalia Fiuczek +8
We demonstrate electrically pumped III-nitride edge-emitting laser diodes (LDs) with nanoporous bottom cladding. The LD structure was grown by plasma-assisted molecular beam epitax…
GaN-based Bipolar Cascade Lasers with 25nm wide Quantum Wells: Simulation and Analysis
J. Piprek, G. Muziol, M. Siekacz +1
We analyze internal device physics, performance limitations, and optimization options for a unique laser design with multiple active regions separated by tunnel junctions, featurin…
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…
Highly efficient optical transition between excited states in wide InGaN quantum wells
Grzegorz Muziol, Henryk Turski, Marcin Siekacz +6
There is a lack of highly efficient light emitting devices (LEDs) operating in the green spectral regime. The devices based on (In,Al)GaN show extremely high efficiencies in violet…
