Novel Reconstruction mechanisms: A comparison between group-III-nitrides and "traditional" III-V-semiconductors
T. K. Zywietz, J. Neugebauer, M. Scheffler +1
We have studied the driving forces governing reconstructions on polar GaN surfaces employing first-principles total-energy calculations. Our results reveal properties not observed…
Adatom Diffusion at GaN (0001) and (000bar1) Surfaces
T. Zywietz, J. Neugebauer, M. Scheffler
The diffusion of Ga and N adatoms has been studied for the technologically relevant wurtzite (000bar1) and (0001) surfaces employing density-functional theory. Our calculations rev…
Clean and As-covered zinc-blende GaN (001) surfaces: Novel surface structures and surfactant behavior
Joerg Neugebauer, Tosja Zywietz, Matthias Scheffler +2
We have investigated clean and As-covered zinc-blende GaN (001) surfaces, employing first-principles total-energy calculations. For clean GaN surfaces our results reveal a novel su…
