GaN; ion implantation; implantation disorder; annealing
The current status of ion beam processing of GaN is reviewed. In particular, we discuss the following aspects of ion implantation into GaN: (i) damage build-up and amorphization, (ii) preferential surface disordering and loss of nitrogen during ion bombardment, (iii) ion-beam-induced porosity of amorphous GaN due to material dissociation, (iv) anomalous surface erosion during ion bombardment at elevated temperatures, (v) the effect of implantation disorder on mechanical properties, (vi) current progress on annealing of implantation disorder, (vii) electrical and optical doping, and (viii) electrical isolation. Emphasis is given to current problems which may hinder a successful application of ion implantation in the fabrication of GaN-based devices. (C) 2001 Elsevier Science B.V. All rights reserved.
