This review presents an overview of the thermal properties of mesoscopic structures. The
discussion is based on the concept of electron energy distribution, and, in particular, on …

A superconductor with a gap in the density of states or a quantum dot with discrete energy
levels is a central building block in realizing an electronic on-chip cooler. They can work as …

Using ultrafast optical pump-probe spectroscopy, we have measured carrier relaxation times
in epitaxial graphene layers grown on SiC wafers. We find two distinct time scales …

Pulsed lasers operating in the mid-infrared (3–20 μm) are important for a wide range of
applications in sensing, spectroscopy, imaging and communications. Despite recent …

In this work we consider the hydrodynamic behavior of a coupled electron–phonon fluid,
focusing on electronic transport under the conditions of strong phonon drag. This regime …

A quantitative correlation between the Urbach energy (E u) and asymmetry parameter q of
Raman spectra has been derived. For this purpose, the effect of electronic disorder (∼ E u) …

We calculate the heat flux and electron-phonon thermal conductance in a disordered
graphene sheet, going beyond a Fermi's golden rule approach to fully account for the …

The classical ferroelectric material BaTiO 3 has been doped with large cation ie, Hf at Ti site
in order to understand the effect of structural disorder in electronic and phononic state. The …

We develop a high frequency, wide bandwidth radiometer operating at room temperature,
which augments the traditional technique of Johnson noise thermometry for nanoscale …

Temperature-dependent Raman spectroscopy, X-ray absorption near-edge spectroscopy
(XANES), optical absorption spectroscopy (OAS) and ac-susceptibility measurements have …
