1Measurement of thermal boundary conductance between metal and dielectric materials using femtosecond laser transient thermoreflectance technique显示文摘The thermal boundary conductance of Al/SiO2, Al/Si, Au/SiO2, and Au/Si are measured by a femtosecond laser transient thermoreflectance technique. The distinct differences of the interfacial thermal conductance between these samples are observed. For the same metal film, the thermal boundary conductance between metal and substrate decreases with the thermal conductivity of the substrate. The measured results are explained with the phonon diffusion mismatch model by introducing a phonon transmission coefficient across the interface.ZHANG ChungWei BI KeDong WANG JianLi NI ZhongHua CHEN YunFei 2012Science China(Technological Sciences)2012,55,4:4

4The oscillatory damped behavior of double wall carbon nanotube oscillators in gaseous environment显示文摘The mechanical oscillatory behaviors of multiwall carbon nanotube oscillators in gaseous environment are investigated using the molecular dynamics method. The effects of ambient gas and temperature on intertube frictional force and oscillation frequency are analyzed. It is found that the intertube frictional force increases with the ambient gas density and temperature. Higher gas density and higher tem- perature cause a more rapid decay in the oscillation amplitude and an increase of the oscillation fre- quency. Compared to the vacuum environmental condition, the collision between gas atoms and the nanotube walls is a main ingredient leading to the increase of the energy dissipation. Gas damping may be the main reason for the failure of carbon nanotube oscillators working in gas environment. The am- bient temperature also has an important effect on oscillations and low temperature is advantageous to sustain oscillations.LI Jian BI KeDong CHEN MinHua CHEN YunFei 2009Science China(Technological Sciences)2009,52,4:0
