Outline of Final Research Achievements

Electrical devices of one-dimensional nanostructures have been fabricated, and their mechanical and electrical properties have been investigated by using the in situ TEM method. The electron mobility of silicon nanowires could be enhanced 3.8 times under a tensile strain 3.4 %, and could be linearly and reversibly increased 2.7 times under a bending strain up to 14.7 %. In addition, transistors and vacuum tubes of single walled carbon nanotubes with the diameter ~1 nm have been successfully fabricated, with the chirality dependent transport properties demonstrated. Furthermore, deformation of atomically thin two-dimensional crystals has been studied, revealing the ultimately high flexibility, paving the way for the high performance flexible electronic devices.
