Ab initio study of hydrogenic effective mass impurities in Si nanowires

Peelaers, H.; Durgun, Engin; Partoens, B.; Bilc, D. I.; Ghosez, P.; Van De Walle C. G.; Peeters, F. M. (Institute of Physics Publishing, 2017-01)

The effect of B and P dopants on the band structure of Si nanowires is studied using electronic structure calculations based on density functional theory. At low concentrations a dispersionless band is formed, clearly ...
Lateral and vertical heterostructures of h-GaN/h-AlN: electron confinement, band lineup, and quantum structures

Onen, A.; Kecik, D.; Durgun, Engin; Çıracı, Salim (American Chemical Society, 2017-11)

Lateral and vertical heterostructures constructed of two-dimensional (2D) single-layer h-GaN and h-AlN display novel electronic and optical properties and diverse quantum structures to be utilized in 2D device applications. ...
