Direct observation of resonant tunneling in heterostructure with a single quantum well
/en/research/publications/direct-observation-of-resonant-tunneling-in-heterostructure-with-a-single-quantum-well
A resonant-tunneling conductivity was experimentally registered in a doped heterostructure with a single quantum well using admittance spectroscopy. Earlier, this effect was only realized in…
A carbon-doping related luminescence band in GaN revealed by below bandgap excitation
/en/research/publications/a-carbon-doping-related-luminescence-band-in-gan-revealed-by-below-bandgap-excitation
Carbon doped GaN grown by hydride vapor phase epitaxy was investigated by photoluminescence and photoluminescence excitation spectroscopy covering a broad range of carbon concentrations. Above…
Toward the first D-band Point to multipoint wireless system field test
/en/research/publications/toward-the-first-d-band-point-to-multipoint-wireless-system-field-test
The European Commission Horizon 2020 ULTRAWAVE "Ultra capacity wireless layer beyond 100 GHz based on millimeter waves" is in the final stage of development. The first ever field test…
A Digital Correction Method for Increased Dynamic Range in Interferometric Six-Port Radars
/en/research/publications/a-digital-correction-method-for-increased-dynamic-range-in-interferometric-six-port-radars
In this letter, we demonstrate a digital correction method for extending the dynamic range of a six-port radar system based on detector diodes. An individual diode gain is considered to depend on…
Shifted excitation Raman difference spectroscopy as enabling technique for the analysis of animal feedstuff
/en/research/publications/shifted-excitation-raman-difference-spectroscopy-as-enabling-technique-for-the-analysis-of-animal-feedstuff
To achieve the best performance and health in farm animals, high-quality pellets should be applied for feeding. Raw materials used for pellet production can have a significant influence on the…
Modelling of a miniature microwave driven nitrogen plasma jet and comparison to measurements
/en/research/publications/modelling-of-a-miniature-microwave-driven-nitrogen-plasma-jet-and-comparison-to-measurements
The MMWICP (miniature microwave ICP) is a new plasma source using the induction principle. Recently Klute et al presented a mathematical model for the electromagnetic fields and power balance of the…
Pulsed Diode Laser Minibars for Pumping Space-Borne Solid-State Lasers
/en/research/publications/pulsed-diode-laser-minibars-for-pumping-space-borne-solid-state-lasers
Laser diode benches (LDBs) with lasing wavelength of 808 nm were developed, manufactured and endurance-tested for utilization as pump lasers for the Nd:YAG oscillator in the climate satellite…
Time-domain optics for atomic quantum matter
/en/research/publications/time-domain-optics-for-atomic-quantum-matter
We investigate time-domain optics for atomic quantum matter. Within a matter-wave analog of the thin-lens formalism, we study optical lenses of different shapes and refractive powers to precisely…
16.3 W Peak-Power Pulsed All-Diode Laser Based Multi-Wavelength Master-Oscillator Power-Amplifier System at 964 nm
/en/research/publications/163-w-peak-power-pulsed-all-diode-laser-based-multi-wavelength-master-oscillator-power-amplifier-system-at-964-nm
An all-diode laser-based master oscillator power amplifier (MOPA) configuration for the generation of ns-pulses with high peak power, stable wavelength and small spectral line width is presented. The…
Subsequent treatment of leafy vegetables with low doses of UVB-radiation does not provoke cytotoxicity, genotoxicity, or oxidative stress in a human liver cell model
/en/research/publications/subsequent-treatment-of-leafy-vegetables-with-low-doses-of-uvb-radiation-does-not-provoke-cytotoxicity-genotoxicity-or-oxidative-stress-in-a-human-liver-cell-model
Ultraviolet B (UVB) radiation in low but ecological-relevant doses acts as a regulator in the plant’s secondary metabolism. This study investigates the effect of UVB radiation from light-emitting…
