Assessment of the overall resource consumption of germanium wafer production for high concentration photovoltaics
The overall resource requirements for the production of germanium wafers for III–V multi-junction solar cells applied in concentrator photovoltaics have been assessed based on up to date process information. By employing [...]
Characterization of Traps in GaN pn Junctions Grown by MOCVD on GaN Substrate Using Deep-Level Transient Spectroscopy
Minority- and majority-carrier traps were studied in GaN pn junctions grown homoepitaxially by MOCVD on n+ GaN substrates. Two majority-carrier traps (MA1,MA2) and three minority-carrier traps (MI1, MI2, [...]
Analyses of Five Major LED Manufacturers Vertical Integration Strategies (Part 2)
In part one of these series, LEDinside explored Philips, Osram and Cree’s vertical integration strategies. In the second part of this series we will take a closer look at major Chinese LED companies MLS and Elech-Tech [...]

LED Wafer on Silicon
We offer high performance blue light-emitting diode prototypes that grow 2” gallium (GaN) layers
based on LED structure on silicon substrate as well as sapphire substrates. Silicon is a low-cost
compared with sapphire substrates, and large diameter silicon wafer processing is already popular
in the [...]
