Abstract
Aiming to realize the thermal-driven actuators in nanometer scale, we have fabricated a bimetal-type nanocomponent consisting of a boron nitride nanotube (BNNT) with platinum (Pt). Previous studies suggested that the high rigidity of the BNNT must work as the resistance to the thermal deformation of this actuator. In this study, we performed the Ar ion etching of individual Pt/BNNT bicomponents in order to control the strength of the mechanical strength of entire system, and the deformation with elevating temperature was observed by a transmission electron microscope (TEM). As the result, it was found that Pt/BNNT partially etched by the ion irradiation showed bending deformation at 〜100℃ due to the thermal expansion of Pt.
