Dynamics of Atomic Steps on GaN (0001) during Vapor Phase Epitaxy
Guangxu Ju, Dongwei Xu, Carol Thompson +5
Images of the morphology of GaN (0001) surfaces often show half-unit-cell-height steps separating a sequence of terraces having alternating large and small widths. This can be expl…

Kinetic Monte Carlo simulations of GaN homoepitaxy on c- and m-plane surfaces
Dongwei Xu, Peter Zapol, G. Brian Stephenson +1
The surface orientation can have profound effects on the atomic-scale processes of crystal growth, and is essential to such technologies as GaN-based light-emitting diodes and high…

Equilibrium and Stability of Polarization in Ultrathin Ferroelectric Films with Ionic Surface Compensation
G. Brian Stephenson, Matthew J. Highland
Thermodynamic theory is developed for the ferroelectric phase transition of an ultrathin film in equilibrium with a chemical environment that supplies ionic species to compensate i…
