However, similar effects in III-nitrides have not been studied in any detail, yet. In the present study, swift heavy ion-induced intermixing of nearly lattice-matched Al (1-x) In x N/GaN heterostructures have been investigated using Rutherford backscattering spectrometry and high-resolution X-ray diffraction techniques. Inter-diffusion of Ga and In elements across the Al (1-x) In x N/GaN interface and the consequent formation of a new mixed quaternary alloy (AlGaInN) layer have been observed. The influence of electronic energy loss of SHI on intermixing effects has been studied. © 2012 Copyright Taylor and Francis Group, LLC. | Source Title: | Radiation Effects and Defects in Solids | URI: | http://scholarbank.nus.edu.sg/handle/10635/98770 | ISSN: | 10420150 | DOI: | 10.1080/10420150.2012.662977 |
