Field-effect transistors (FETs) have been developed from silicon based to carbon nanotubes (CNTs) based, and the fabrication space became three-dimensionl (3D). Such fabrication process requires to accurately assemble a single CNT in 3D. However, most of the current assembly technologies were used for planar structures but not for 3D structures. In this study, we aim to use nanomanipulation based...
Although a variety of carbon nanotube field-effect transistors (CNTFETs) have been successfully fabricated, the contact property between multi-walled carbon nanotubes (MWCNTs) and electrodes is still elusive. In this study, we aims at further characterizing the contact properties among MWCNTs, Au electrode (gold coated glass substrate) and tungsten deposit. First, an atomic force microscope (AFM)...
This paper presents In situ quick repairing of defects inside a telescoping multi-walled carbon nanotubes (MWCNTs) using contact resistance. The defects were inserted and repaired by In situ nanomanipulation technique inside a transmission electron microscope (TEM). The defects were quickly (less than ∼0.1 s) repaired by applying a current after contact with electrode. The repairing of defects was...
In situ fabrication and electrostatic actuation of a telescoping multi-walled carbon nanotube are presented. The inner core of the telescoping nanotube is actuated by applied bias voltage with a certain gap inside a vacuum chamber. From modeling analysis, the electrostatic forces are mainly driven force for actuation. At the experimental section, one end opened telescoping multi-walled carbon nanotube...
