Role of quasi-Fermi levels in Si- and Mg-related optical absorption in nitride laser diodes (LDs): material context
Konrad Sakowski, Cyprian Sobczak, Pawel Strak +5
Optical absorption and reabsorption of light emitted from active regions in nitride laser diodes (LDs) have been shown to reduce the light extraction efficiency of these devices. I…

Fundamentals of the metal contact to p-type GaN: new multilayer design
Konrad Sakowski, PaweÅ Strak, Stanislaw Krukowski
Electrical properties of contact to p-type nitride semiconductor devices, based on gallium nitride were simulated by ab initio and by drift-diffusion calculations. The contact elec…

Quantum effects in surface diffusion: application to diffusion of nitrogen adatoms over GaN(0001) surface
PaweÅ Strak, Cyprian Sobczak, Stanislaw Krukowski
It is shown that quantum effects play determining role in nitrogen adatom diffusion due to several different factors. This could be related to the change of the energy of the quant…
