Improved AlGaN UV photodetectors by interface conduction

28.07.2016

Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik

Our partner Ferdinand-Braun-Institut developed a metal-semiconductor-metal photodetector  with thin AlGaN absorber layers on AlN/Sapphire templates that show high external quantum efficiencies (EQE) saturating at about 70% when the PD is illuminated from the substrate side. The AlxGa1-xN material system is attractive for the detection of ultraviolet (UV) radiation. Owing to the dependence of the large band gap energy on Al mole fraction x (3.4 eV to 6.2 eV), the cut-off wavelength of photodetectors is adjustable between 365 nm and 210 nm. Moreover, the material is robust against UV-radiation.

EpiTT for UV-C LEDs: 280 nm reflectance senses AlGaN surface morphology

28.06.2016

LayTec AG

AlGaN buffer layers with high Aluminum content are necessary for optimal UV-C LED performance. But their Band-Edge lies below 300 nm, so the established 405 nm in-situ reflectance is insensitive to the surface morphology of such AlGaN layers. To monitor precisely both AlGaN growth rate and surface morphology during UV-C LED epitaxy, LayTec offers an additional 280 nm reflectance channel that employs a UV-C LED as a light source.

Quantification of matrix and impurity elements in AlxGa1-xN compounds by Secondary Ion Mass Spectrometry

25.04.2016

Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik

The AlGaN material system is of increasing interest for UV-based optoelectronic devices such as light emitting diodes (LEDs), laser diodes and photodetectors. The electronic properties of AlxGa1-xN compounds are strongly influenced by the mole fraction x of AlN, as well as by the content of residual impurities and dopant elements like H, C, O, Si, and Mg.
