采用脉冲激光沉积法合成了一种碳纳米管模板夹在氧化铝和氧化钨薄层上的复合无机纳米线（NW），并观察了其热诱导的纳米力学挠曲现象。由于涂层的热膨胀系数不同，杂化NW在室温至800℃的试样温度范围内逐渐弯曲。这种机械偏转表现出可重复性。
We observed thermally induced nanomechanical deflection of a hybrid inorganic nanowire (NW) synthesized by pulsed-laser deposition, the structure of which is a carbon nanotube template sandwiched by aluminum oxide and tungsten oxide thin layers. The hybrid NW was gradually bent at a specimen temperature ranging from room temperature to 800 °C, due to the different coefficients of thermal expansion of the coated layers. This mechanical deflection exhibited repeatability.
