Impulsive stimulated Brillouin scattering in KD 2 PO 4 near the structural phase transition
TL;DR: Impulsive stimulated Brillouin scattering is used to characterize anomalous and highly dispersive acoustic behavior, including heavily overdamped acoustic motion, in KD 2 PO 4 crystals near the structural phase transition temperature T c, suggesting applications in efficient light modulation and switching as discussed by the authors.
Journal ArticleDOI
Gas-pressure chemical vapor transport growth of millimeter-sized c-BAs single crystals with moderate thermal conductivity
Jie Xing,Evan R. Glaser,Bai Song,James C. Culbertson,Jaime A. Freitas,R. A. Duncan,Keith A. Nelson,Gang Chen,Ni Ni +8 more
TL;DR: In this paper, the authors have grown c-BAs single crystals up to 1000 µm size by the chemical vapor transport (CVT) technique using combined As and I2 transport agents with the As:I ratio of 1:3 under gas pressures of up to 35 µm.
Journal ArticleDOI
Unifying first-principles theoretical predictions and experimental measurements of size effects in thermal transport in SiGe alloys
Samuel Huberman,Vazrik Chiloyan,R. A. Duncan,Lingping Zeng,Roger Jia,Alexei Maznev,Eugene A. Fitzgerald,Keith A. Nelson,Gang Chen +8 more
TL;DR: In this article, the authors demonstrate the agreement between first-principles calculations and experimental measurements of size effects in thermal transport in SiGe alloys without fitting parameters, and they provide a framework for the study of size effect on thermal conductivity in opaque materials.
