205 カーボンナノチューブの電気伝導特性に及ぼす局所ひずみ分布の影響(OS2-2.電子デバイス・電子材料と計算力学(2),OS・一般セッション講演)

Abstract

The prediction of the change in conductivity of carbon nanotubes (CNTs) under strain is crucially important to assure the reliability of the performance of CNT-based electronic devices. In this study, the change of the electronic state of CNTs caused by deformation was analyzed. We found that the change of the electronic sate of CNTs was mainly dominated by (a) a change in the bond length ratio in a six-membered ring and (b) increase in the local curvature leading to an orbital hybridization.
