Ab initio determination of ultrahigh thermal conductivity in ternary compounds
Huan Wu, Hang Fan, Yongjie Hu
Discovering new materials with ultrahigh thermal conductivity has been a critical research frontier and driven by many important technological applications ranging from thermal man…
Basic Physical Properties of Cubic Boron Arsenide
Joon Sang Kang, Man Li, Huan Wu +2
Cubic boron arsenide (BAs) is an emerging semiconductor material with a record-high thermal conductivity of 1300 W/mK. However, many fundamental properties of BAs remain unexplored…
Role of higher-order phonon scattering in the zone-center optical phonon linewidth and the Lorenz oscillator model
Xiaolong Yang, Tianli Feng, Joon Sang Kang +3
Zone-center optical phonon linewidth is a key parameter for infrared and Raman spectra as well as the Lorenz oscillator model. While three-phonon scattering was often assumed to be…
Anisotropic thermal conductivity measurement using a new Asymmetric-Beam Time-Domain Thermoreflectance (AB-TDTR) method
Man Li, Joon Sang Kang, Yongjie Hu
Anisotropic thermal properties are of both fundamental and practical interests, but remain challenging to characterize using conventional methods. In this work, a new metrology bas…
No energy transport without discord
Seth Lloyd, Zi-Wen Liu, Stefano Pirandola +4
We show that without quantum correlations, energy cannot flow. The result follows from a simple theorem that shows that systems whose dynamics do not generate quantum discord are e…
Electric Field Effect Thermoelectric Transport in Individual Silicon and Germanium/Silicon Nanowire
Yuri M. Brovman, Joshua P. Small, Yongjie Hu +3
We have simultaneously measured conductance and thermoelectric power (TEP) of individual silicon and germanium/silicon core/shell nanowires in the field effect transistor device co…
Spin Relaxation in Ge/Si Core-Shell Nanowire Qubits
Yongjie Hu, Ferdinand Kuemmeth, Charles M. Lieber +1
Controlling decoherence is the most challenging task in realizing quantum information hardware. Single electron spins in gallium arsenide are a leading candidate among solid- state…
Double quantum dot with integrated charge sensor based on Ge/Si heterostructure nanowires
Yongjie Hu, Hugh H. O. Churchill, David J. Reilly +3
Coupled electron spins in semiconductor double quantum dots hold promise as the basis for solid-state qubits. To date, most experiments have used III-V materials, in which coherenc…
