Fully atomistic simulations of phonon-limited mobility of electrons and holes in <001>-, <110>-, and <111>-oriented Si nanowires

Y.M. Niquet, C. Delerue, D. Rideau, Brice Videau

Phonon-limited mobilities of electrons and holes in Si nanowires (NWs) with 〈001〉, 〈110〉, and 〈111〉 orientations are calculated in a fully atomistic framework for diameters up to 10 nm. Electron-phonon scattering rates are computed with an sp3d5s* tight-binding model for electrons and a valence…

CBRAM devices as binary synapses for low-power stochastic neuromorphic systems: auditory (cochlea) and visual (retina) cognitive processing applications

M. Suri, O. Bichler, D. Querlioz, G. Palma, E. Vianello, D. Vuillaume, C. Gamrat, B. de Salvo

In this work, we demonstrate an original methodology to use Conductive-Bridge RAM (CBRAM) devices as binary synapses in low-power stochastic neuromorphic systems. A new circuit architecture, programming strategy and probabilistic STDP learning rule are proposed. We show, for the first time, how the…

Tight-binding calculations of the optical properties of HgTe nanocrystals

Guy Allan, Christophe Delerue

We propose a tight-binding model of HgTe which gives an accurate band structure in a wide energy range compared to recent ab initio calculations. The inverted band structure near the Fermi level and its temperature dependence are also very well described. Using this parametrization, we study the…

Experimental evidence of zero-angle refraction and acoustic wave-phase control in a two-dimensional solid/solid phononic crystal

Jerome O. Vasseur, B. Morvan, A. Tinel, N. Swinteck, Anne-Christine Hladky, P.A. Deymier

The square symmetry of the equifrequency contour of longitudinal waves in a solid/solid two-dimensional phononic crystal (PC) is shown through numerical calculations and experiments to lead to peculiar propagation phenomena. A slab of steel/epoxy PC immersed in water refracts incident longitudinal…

A study on millimetre-wave tunable bandpass filter based on polymer cap deflection

S. Seok, J.G. Kim, N. Rolland, P.A. Rolland

This paper presents a new tuning mechanism for millimetre-wave BPF based on deflection of the BCB membrane of BCB packaging cap. A 3-pole parallel-coupled microstrip filter operating at 60 GHz is first implemented on 30 µm-thick BCB polymer substrate and then BCB-capped through our new anti…
