Filamentary Switching: Synaptic Plasticity through Device Volatility
Selina La Barbera, Dominique Vuillaume, Fabien Alibart
Replicating the computational functionalities and performances of the brain remains one of the biggest challenges for the future of information and communication technologies. Such…
Influence of Molecular Organization on the Electrical Characteristics of π-conjugated Self-assembled Monolayers
Xavier Lefevre, Fabrice Moggia, Olivier Segut +10
Two new thiol compounds with σ-π-σ structure were synthesized and self-assembled on gold substrates. The morphology and the structural characterization of SAMs assessed by infrared…
Non-Arrhenius conduction due to the interface-trap-induced disorder in X-doped amorphous InXZnO thin-film transistors
Mohammed Benwadih, J. A. Chroboczek, Gerard Ghibaudo +2
Thin film transistors, with channels composed of In-X-Zn oxides, IXZO, with X dopants: Ga, Sb, Be, Mg, Ag, Ca, Al, Ni, and Cu, were fabricated and their I-V characteristics were ta…
Low voltage and time constant organic synapse-transistor
Simon Desbief, Adrica Kyndiah, David Guerin +7
We report on an artificial synapse, an organic synapse-transistor (synapstor) working at 1 volt and with a typical response time in the range 100-200 ms. This device (also called N…
Topological states in multi-orbital HgTe honeycomb lattices
W. Beugeling, E. Kalesaki, C. Delerue +3
Research on graphene has revealed remarkable phenomena arising in the honeycomb lattice. However, the quantum spin Hall effect predicted at the K point could not be observed in gra…
Formation of quantum dots in the potential fluctuations of InGaAs heterostructures probed by scanning gate microscopy
P. Liu, F. Martins, B. Hackens +6
The disordered potential landscape in an InGaAs/InAlAs two-dimensional electron gas patterned into narrow wires is investigated by means of scanning gate microscopy. It is found th…
