WebMar 29, 2024 · As a sensitive probe of the electron system, we focus on current fluctuations induced by nonequilibrium electrons, or shot noise ( 17 ), which has proven to contain nanoscopic information of electron motion not obtained from standard resistance measurements ( 17 – 20 ). WebThe noise equivalent bandwidth takes into account the additional noise beyond the filter cutoff frequency due to the gradual roll-off of the filter. The noise equivalent bandwidth is dependent on the number of poles in the filter and the filter type. For a simple one pole, low-pass Butterworth filter, the NEBW is 1.57 × filter cutoff.

WebOct 25, 2008 · Potential steps naturally develop in graphene near metallic contacts. We investigate the influence of these steps on the transport in graphene field effect transistors. We give simple expressions to estimate the voltage-dependent contribution of the contacts to the total resistance and noise in the diffusive and ballistic regimes.
