Formation and phase transformation of Bi-containing QD-like clusters in annealed GaAsBi

We report the formation and phase transformation of Bi-containing clusters in ##IMG## [http://ift.tt/1n2CugN] {$\text{GaA}{{\text{s}}_{1-x}}$} Bi ##IMG## [http://ift.tt/1nIgCtv] {$_{x}$} epilayers upon annealing. The ##IMG## [http://ift.tt/1n2CvBj] {$\text{GaA}{{\text{s}}_{1-x}}$} Bi ##IMG## [http://ift.tt/1nIgBpk] {$_{x}$} layers were grown by molecular beam epitaxy under low (220 ##IMG## [http://ift.tt/1n2Cuxj] {$^{{}^\circ }\text{C}$} ) and high (315 ##IMG## [http://ift.tt/1n2CuNz] {$^{{}^\circ }\text{C}$} ) temperatures and subsequently annealed using different temperatures and a...
