High temperature acidic oxidation of multiwalled Carbon nanotubes and synthesis of Graphene quantum dots
The acid oxidation of carbon nanotube generally results in opening the close ends of the nanotube and to make surface modifications. Herewith, Multiwall carbon nanotubes (MWCNTs) were oxidized in acids at high temperature experimental conditions which led to the formation of graphene quantum dots (GQDs). High resolution transmission electron microscope (HRTEM), energy dispersive X-ray spectro...
متن کاملTerahertz sensing and imaging based on carbon nanotubes: frequency- selective detection and near-field imaging
The advantageous properties of terahertz (THz) waves permeability through objects opaque for visible light, the important energy spectrum in the meV range, etc. potentially enable various applications of sensing and imaging in this band. Lowdimensional electronic structures open up novel THz technologies, such as quantum cascade laser and THz time-domain spectroscopy. In this work, by employing...

متن کاملCarbon nanotube terahertz detector.
Terahertz (THz) technologies are promising for diverse areas such as medicine, bioengineering, astronomy, environmental monitoring, and communications. However, despite decades of worldwide efforts, the THz region of the electromagnetic spectrum still continues to be elusive for solid state technology. Here, we report on the development of a powerless, compact, broadband, flexible, large-area, ...
متن کاملReal time electron tunneling and pulse spectroscopy in carbon nanotube quantum dots.
We investigate a quantum dot (QD) in a carbon nanotube (CNT) in the regime where the QD is nearly isolated from the leads. An aluminum single electron transistor (SET) serves as a charge detector for the QD. We precisely measure and tune the tunnel rates into the QD in the range between 1 kHz and 1 Hz, using both pulse spectroscopy and real-time charge detection, and measure the excitation spec...
