چکیده
Abstract The far-infrared emission properties of epitaxial graphene on SiC obtained by current injection were investigated using an infrared camera and Fourier-transform spectroscopy. radiation directivity from the emitter was observed in directions perpendicular to surface edge sample. energy density larger than that all directions. maximum measured temperature change at 0.4 W for 76.1 K a tilt angle 50° 54.1 0°. A blackbody-like spectrum with constant peak wavelength 10.0 μ m, regardless applied electrical power, both edge. light successfully realized single-crystal SiC.

Thermal infrared emission from biased graphene.
The high carrier mobility and thermal conductivity of graphene make it a candidate material for future high-speed electronic devices. Although the thermal behaviour of high-speed devices can limit their performance, the thermal properties of graphene devices remain incompletely understood. Here, we show that spatially resolved thermal radiation from biased graphene transistors can be used to ex...
متن کاملUltrasensitive graphene far-infrared power detectors.
We describe the properties of ultrasensitive graphene photon detectors for use in the far-infrared/terahertz spectral region and present theoretical predictions for their power detection sensitivity. These predictions are based on two graphene contacting schemes with superconducting contacts: contacts with a thin insulating barrier, and direct superconducting contacts. To quantitatively assess ...
متن کاملPolarized Far-infrared and Submillimeter Emission from Interstellar Dust
Polarized far-infrared and submillimeter emission is calculated for models of nonspherical dust grains that are constrained to reproduce the observed wavelength-dependent extinction and polarization of starlight. For emission from regions where the magnetic field is perpendicular to the line-of-sight, the far-infrared emission is expected to have substantial linear polarization at wavelengths λ...
متن کاملHerMES: the far-infrared emission from dust-obscured galaxies
Dust-obscured galaxies (DOGs) are an ultraviolet-faint, infrared-bright galaxy population that reside at z ∼ 2 and are believed to be in a phase of dusty star-forming and active galactic nucleus (AGN) activity.We present far-infrared (far-IR) observations of a complete sample of DOGs in the 2 deg of the Cosmic Evolution Survey. The 3077 DOGs have 〈z〉 = 1.9 ± 0.3 and are selected from 24μm and r...
متن کاملMonte Carlo Predictions of Far-Infrared Emission from Spiral Galaxies
We present simulations of Far Infrared (FIR) emission by dust in spiral galaxies, based on the Monte Carlo radiative transfer code of Bianchi, Ferrara & Giovanardi (1996). The radiative transfer is carried out at several wavelength in the Ultraviolet (UV), optical and Near Infrared (NIR), to cover the range of the stellar Spectral Energy Distribution (SED). Together with the images of the galac...
