Panel Design of a MIMO Imaging Radar at W-Band for Space Applications
/en/research/publications/panel-design-of-a-mimo-imaging-radar-at-w-band-for-space-applications
This paper describes the concept of a modularized multiple input multiple output (MIMO) imaging radar in the frequency range of 85 to 95GHz that enables high resolution 3D imaging for space…
Effect of Cl2 plasma treatment and annealing on vanadium based metal contacts to Si-doped Al0.75Ga0.25N
/en/research/publications/effect-of-cl2-plasma-treatment-and-annealing-on-vanadium-based-metal-contacts-to-si-doped-al075ga025n
In order to understand the electrical properties of V/Al/Ni/Au metal contacts to Si-doped Al0.75Ga0.25N layers, X-ray photoelectron spectroscopy analysis was performed on differently treated AlGaN:Si…
Efficient coupling of the inhomogeneous current spreading model to the dynamic electro-optical solver for broad-area edge-emitting semiconductor devices
/en/research/publications/efficient-coupling-of-the-inhomogeneous-current-spreading-model-to-the-dynamic-electro-optical-solver-for-broad-area-edge-emitting-semiconductor-devices
We extend a 2 (space) + 1 (time)-dimensional traveling wave model for broad-area edge-emitting semiconductor lasers by a model for inhomogeneous current spreading from the contact to the active zone…
MOVPE growth of violet GaN LEDs on β-Ga2O3 substrates
/en/research/publications/movpe-growth-of-violet-gan-leds-on-beta-ga2o3-substrates
We report that a H2-free atmosphere is essential for the initial stage of metalorganic vapour phase epitaxy (MOVPE) growth of GaN on β-Ga2O3 to prevent the surface from damage. A simple growth…
