Shot noise, originating from the discrete nature of electric charge, is generated by scattering
processes. Shot-noise measurements have revealed microscopic charge dynamics in …

Carrier mobility in solids is generally limited by electron-impurity or electron–phonon
scattering, depending on the most frequently occurring event. Three-body collisions …

We have investigated the energy loss of hot electrons in metallic graphene by means of GHz
noise thermometry at liquid helium temperature. We observe the electronic temperature T∝ …

Advances in nanotechnology have allowed physicists and engineers to miniaturize
electronic structures to the limit where finite-size related phenomena start to impact their …

A bolometer is a device that makes an electrical resistive response to the electromagnetic
radiation resulted from a raise of temperature due to heating. The combination of the …

In the last decade, graphene has become an exciting platform for electron optical
experiments, in some aspects superior to conventional two-dimensional electron gases …

Achieving a population imbalance between the two inequivalent valleys is a critical first step
for any valleytronic device. A valley polarization can be induced in biased bilayer graphene …

Current noise in nanoscale systems provides additional information beyond the electronic
conductance. We report measurements at room temperature of the nonequilibrium “excess” …

Using electrical transport experiments and shot noise thermometry, we investigate electron-
phonon heat transfer rate in a suspended bilayer graphene. Contrary to monolayer …

Noise equivalent power and time constant of a submillimeter wave hot-electron bolometer
(HEB) made from monolayer graphene are analyzed using the lowest electron-phonon …
