Twin Domains in 111 oriented {CdO/MgO} superlattices: homoepitaxy versus heteroepitaxy
Ewa Przeździecka, Aleksandra Wierzbicka, Abinash Adhikari +1
The structural properties of (111)-oriented {CdO/MgO} superlattice structures grown on c-sapphire and cubic MgO substrates have been studied by high resolution X-ray diffraction. T…
Fundamentals of the metal contact to p-type GaN: new multilayer design
Konrad Sakowski, Paweł 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…
Strain distribution in GaN/AlN superlattices grown on AlN/sapphire templates: comparison of X-ray diffraction and photoluminescence studies
Aleksandra Wierzbicka, Agata Kaminska, Kamil Sobczak +5
Series of GaN/AlN superlattices (SLs) with various periods and the same thicknesses of GaN quantum wells and AlN barriers have been investigated. X-ray diffraction, photoluminescen…
Quantum effects in surface diffusion: application to diffusion of nitrogen adatoms over GaN(0001) surface
Paweł 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…
Charge control of semiconductor surfaces as elucidated by ab initio calculations a review
Stanisław Krukowski, Pawel Kempisty, Pawel Strak
Recent progress in the investigations of the charge role in semiconductor surfaces is reviewed.
