Characterization and Modeling of Graphene Transistor Low-Frequency Noise

Brice Grandchamp, Sebastien Fregonese, Cédric Majek, Cyril Hainaut, Cristell Maneux, Nan Meng, Henri Happy, Thomas Zimmer

This brief presents low-frequency noise measurements on a graphene field-effect transistor with graphene layer decomposed from SiC substrate. The measurements indicate the predominance of flicker noise in the current noise source measured between drain and source with quadratic dependence with a...

Transport Inefficiency in Branched-Out Mesoscopic Networks: An Analog of the Braess Paradox

M. G. Pala, S. Baltazar, Peng Liu, Hermann Sellier, B. Hackens, F. Martins, Vincent Bayot, X. Wallart, L. Desplanque, Serge Huant

We present evidence for a counterintuitive behavior of semiconductor mesoscopic networks that is the analog of the Braess paradox encountered in classical networks. A numerical simulation of quantum transport in a two-branch mesoscopic network reveals that adding a third branch can paradoxically...

Joint Carrier Frequency Offset and Channel Estimation for OFDM Systems via the EM Algorithm in the Presence of Very High Mobility

Eric Pierre Simon, Laurent Ros, Hussein Hijazi, Mounir Ghogho

In this paper, the problem of joint carrier frequency offset (CFO) and channel estimation for OFDM systems over the fast time-varying frequency-selective channel is explored within the framework of the expectation-maximization (EM) algorithm and parametric channel model. Assuming that the path...

Size-dependence of the exciton transitions in colloidal CdTe quantum dots

Esther Groeneveld, Christophe Delerue, Guy Allan, Yann-Michel Niquet, Celso de Mello Donega

In this paper, we present a detailed investigation of the size dependence of the optical transitions of colloidal CdTe QDs ranging in diameter from 2.9 to 14.8 nm. The energy integrated absorption cross section per CdTe unit is investigated in detail for the lowest two exciton transitions (1S3/2(h...
