Generation of terahertz radiation by hot electrons in carbon nanotubes.

چکیده
We demonstrate theoretically that quasi-metallic carbon nanotubes emit terahertz radiation induced by an applied voltage. It is shown that in the ballistic transport regime their spontaneous emission spectra have a universal frequency and bias voltage dependence, which raises the possibility of utilizing this effect for high-frequency nanoelectronic devices.

Terahertz Dynamics of Quantum-Confined Electrons in Carbon Nanomaterials
Low-dimensional carbon nanostructures, such as single-wall carbon nanotubes (SWCNTs) and graphene, offer new opportunities for terahertz science and technology. Being zero-gap systems with a linear, photon-like energy dispersion, metallic SWCNTs and graphene exhibit a variety of extraordinary properties. Their DC and linear electrical properties have been extensively studied in the last decade,...
متن کاملTerahertz time-domain measurement of ballistic electron resonance in a single-walled carbon nanotube.
Understanding the physics of low-dimensional systems and the operation of next-generation electronics will depend on our ability to measure the electrical properties of nanomaterials at terahertz frequencies ( approximately 100 GHz to 10 THz). Single-walled carbon nanotubes are prototypical one-dimensional nanomaterials because of their unique band structure and long carrier mean free path. Alt...
متن کاملExperimental detection of terahertz radiation in bundles of single wall carbon nanotubes
We present new data extending our previous paper at the ISSTT2006 on microwave detection in carbon nanotubes (CNTs). In particular, we derive a circuit model based on ANA measurements. We also demonstrate the first terahertz detection (up to 2.54 THz) in bundles of CNTs that were deposited through dielectrophoresis across the smallest gap in log-periodic antennas. Data are given that support th...

Luttinger liquid theory predicts that collective electron excitations due to strong electron-electron interactions in a one-dimensional (1D) system will result in a modification of the collective charge-propagation velocity. By utilizing a circuit model for an individual metallic single-walled carbon nanotube as a nanotransmission line, it has been shown that the frequency-dependent terahertz i...
