Electromechanical Investigation of Low Dimensional Nanomaterials for NEMS Applications
Successful operation of Nano-ElectroMechanical Systems (NEMS) critically depends on their working environment and component materials' electromechanical properties. It is equally important that ambient or liquid environment ...
Imaging and manipulating organometallic molecules by scanning tunneling microscopy
Using scanning tunneling microscopy (STM) we have explored complex surface adsorbed molecules, nanocars, on Au(111) and the parameters related to the direct translation of these molecules by the STM tip. Specifically, the ...
Optical Spectroscopy of Single-Walled Carbon Nanotubes Under Extreme Conditions
Single-walled carbon nanotubes (SWNTs) are one of the leading candidate materials to realize novel nanoscale photonic devices. In order to assess their performance characteristics as optoelectronic materials, it is crucial ...
Terahertz Dynamics of Quantum-Confined Electrons in Carbon Nanomaterials
The terahertz (THz) frequency range. 0.1 - 20 THz, exists between the microwave and infrared ranges and contains abundant information on the dynamics of charge and spin carriers in condensed matter systems. Since its advent ...
The transition from a TEM-like mode to a plasmonic mode in finite-width THz parallel-plate waveguides
By the near-field measurement of the electric field distribution inside the finite width THz parallel plate waveguide, we find the transition from conventional diffractive TEM-like mode to plasmonic mode. This mode transition ...
