Light Extraction and External Quantum Efficiency of 235 nm Far–Ultraviolet-C Light-Emitting Diodes on Single-Crystal AlN Substrates
/forschung/publikationen/light-extraction-and-external-quantum-efficiency-of-235nm-far-ultraviolet-c-light-emitting-diodes-on-single-crystal-aln-substrates
The effect of bulk AlN single-crystal substrate thickness on the light extraction efficiency and external quantum efficiency of far ultraviolet-C light emitting diodes (far-UVC LEDs) has been…
Importance of Scaling in RF GaN HEMTs for Reduction of Surface Traps-Induced Drain Lag
/forschung/publikationen/importance-of-scaling-in-rf-gan-hemts-for-reduction-of-surface-traps-induced-drain-lag
Drain lag is a well-known phenomenon that leads to radio frequency performance degradation in AlGaN/GaN high-electron-mobility transistors. Herein, it is demonstrated that a reduction of the…
Time-Resolved Investigations of the Capacitive to Inductive Transition in a Microwave-Driven Plasma Source
/forschung/publikationen/time-resolved-investigations-of-the-capacitive-to-inductive-transition-in-a-microwave-driven-plasma-source
Measurement of resonances requires data acquisition at different frequencies. Tracing the evolution of a resonance, therefore, requires a long time for each step. Reproducible events allow us to…
Combining Bayesian Optimization, Singular Value Decomposition, and Machine Learning for Advanced Optical Design
/forschung/publikationen/combining-bayesian-optimization-singular-value-decomposition-and-machine-learning-for-advanced-optical-design
The design and optimization of optical components, such as Bragg gratings, are critical for applications in telecommunications, sensing, and photonic circuits. To overcome the limitations of…
