Dynamic admittance of carbon nanotube-based molecular electronic devices and their equivalent electric circuit
We use first-principles quantum mechanics to simulate the transient electrical response through carbon nanotube-based conductors under time-dependent bias voltages. The dynamic admittance and time-dependent charge distribution are reported and analyzed. We find that the electrical response of these two-terminal molecular devices can be mapped onto an equivalent classical electric circuit and th...
متن کاملMolecular electronic devices based on single-walled carbon nanotube electrodes.
As the top-down fabrication techniques for silicon-based electronic materials have reached the scale of molecular lengths, researchers have been investigating nanostructured materials to build electronics from individual molecules. Researchers have directed extensive experimental and theoretical efforts toward building functional optoelectronic devices using individual organic molecules and fab...
متن کاملPhysics of carbon nanotube electronic devices
Carbon nanotubes (CNTs) are amongst the most explored one-dimensional nanostructures and have attracted tremendous interest from fundamental science and technological perspectives. Albeit topologically simple, they exhibit a rich variety of intriguing electronic properties, such as metallic and semiconducting behaviour. Furthermore, these structures are atomically precise, meaning that each car...
متن کاملSTATIC AND DYNAMIC RESPONSE OF CARBON NANOTUBE-BASED NANOTWEEZERS
In this paper static and dynamic response of nanotweezers composed of two carbon nanotube (CNT) arms are investigated. Taking into account a continuum model and considering the electrostatic actuation as well as the presence of the van der Waals forces, the static nonlinear equations are solved by a step by step linearization and Galerkin projection method. Simulating the closing dynamics of a ...
متن کاملCarbon nanotube junctions and devices Carbon nanotube junctions and devices
Carbon nanotubes are molecules entirely made of carbon atoms. Owing to their special shape, they are extremely stiff but also very flexible. The electronic properties are determined by the exact symmetry of the nanotube lattice, resulting in either metallic or semiconducting behavior. Due to their small diameter, electronic motion is directed in the length direction of the nanotube, making them...
