Exceptional Optical Phonon Coherence in Enriched Cubic Boron Arsenide via Suppression of Three-Phonon Scattering
Tong Lin, Fengjiao Pan, Gaihua Ye +8
Cubic boron arsenide (BAs) is a promising semiconductor for next-generation electronics due to its outstanding ambipolar mobility and thermal conductivity, the latter of which is a…
Strong Temperature Dependence of Thermal Conductivity in High-Purity Cubic Boron Arsenide
Songrui Hou, Fengjiao Pan, Xinping Shi +11
Materials with high thermal conductivity are needed to conduct heat away from hot spots in high power electronics and optoelectronic devices. Cubic boron arsenide (c-BAs) has a hig…
Thermal Conductivity above 2000 W/m.K in Boron Arsenide by Nanosecond Transducer-less Time-Domain Thermoreflectance
Hong Zhong, Ying Peng, Feng Lin +8
Cubic boron arsenide (c-BAs) has been theoretically predicted to exhibit thermal conductivity \k{appa} comparable to that of diamond, yet experimental measurements have plateaued a…
Thermal conductivity of boron arsenide above 2100 watts per meter per Kelvin at room temperature
Ange Benise Niyikiza, Zeyu Xiang, Fanghao Zhang +6
Boron arsenide (BAs) single crystals had been previously reported to have thermal conductivity of 1500 W/mK at room temperature. Now we achieved thermal conductivity above 2100 W/m…
