Journal ArticleDOI
Characterization of N-polar AlN in GaN/AlN/(Al,Ga)N heterostructures grown by metal-organic chemical vapor deposition
Haoran Li,Baishakhi Mazumder,Bastien Bonef,Stacia Keller,Steven Wienecke,James S. Speck,Steven P. DenBaars,Umesh K. Mishra +7 more
TL;DR: In this paper, the N-polar AlN (Al x Ga1?x N) films examined by atom probe tomography were examined and the aluminum compositions were found to be equal to or higher than 95% over a wide range of growth conditions.
Journal ArticleDOI
