Defects in nitrides, positron annihilation spectroscopy [PDF]

SPIE Proceedings, 2013
ABSTRACT In -grown group III (cation) vacancies (V Ga , V Al , V In ) in GaN, AlN and InN tend to be complexed with donor -type defects These donor defects may in principle be residual impurities such as O or H, n-type dopants such as Si, or intrinsic defects such as the N vacancy (V N ).
