Phase stability, chemical bonds, and gap bowing of In x Ga 1 − x N alloys: Comparison between cubic and wurtzite structures
TL;DR: In this paper, the properties of wurtzite alloys were studied by combining first-principles total energy calculations with the generalized quasichemical approach, and compared to previous results for the zinc-blende structure.
Journal ArticleDOI
An electron diffraction study of solidified mixtures of argon and krypton and of argon and neon
A E Curzon,A J Mascall +1 more
TL;DR: In this paper, the argon-krypton mixture crystallized into a single face-centred cubic phase whose lattice parameter depended in a non-linear manner on the atomic concentration of argon in the mixture and was intermediate between the lattice parameters of the two pure components.
Journal ArticleDOI
Synthesis of Homogeneously Alloyed Cu2−x(SySe1−y) Nanowire Bundles with Tunable Compositions and Bandgaps
Jun Xu,Yongbing Tang,Xue Chen,Chunyan Luan,Wenfeng Zhang,Juan Antonio Zapien,Wenjun Zhang,Hoi-Lun Kwong,Xiang-Min Meng,Shuit-Tong Lee,Chun-Sing Lee +10 more
TL;DR: In this paper, a cubic phased ternary Cu 2 − x (S y Se 1 − y ) compound was found to have similar copper contents (0.37 ≤ x ≤ 0.44) and morphologies, and the same face centered cubic (fcc) crystal structure and growth orientation of y.
Journal ArticleDOI
