A ballistic transport model for an artificial neuron
George Alexandru Nemnes, Daniela Dragoman
We introduce a model for an artificial neuron which is based on ballistic transport in a multi-terminal device. Unlike standard configurations, the proposed design embeds the synap…
Graphene bandgap induced by ferroelectric Pca2 HfO substrate: a first-principles study
George Alexandru Nemnes, Daniela Dragoman, Mircea Dragoman
The electronic properties of graphene on top of ferroelectric HfO substrates in orthorhombic phase with space group Pca2 are investigated using density functional theory ca…
Reconfigurable quantum logic gates using Rashba controlled spin polarized currents
George Alexandru Nemnes, Daniela Dragoman
A reconfigurable logic gate is proposed in a two-dimensional double quantum wire system with a coupling window enabled by a Rashba field. Manipulating the spin states of incoming e…
Electric and thermoelectric properties of graphene bilayers with extrinsic impurities under applied electric field
G. A. Namnes, T. L. Mitran, A. Manolescu +1
In contrast to monolayer graphene, in bilayer graphene (BLG) one can induce a tunable bandgap by applying an external electric field, which makes it suitable for field effect appli…
Ballistic 3-port interferometric logic gates in the quantum Hall regime
A. Radu, S. Iftimie, D. Dragoman
We show that a 3-port interferometer, defined by quantum point contacts in a two-dimensional electron gas, and working in the quantum Hall regime, can implement different logic gat…
Electric field effect in boron and nitrogen doped graphene bilayers
G. A. Nemnes, T. L. Mitran, A. Manolescu +1
Unlike single layer graphene, in the case of -stacked bilayer graphene (BLG) one can induce a non-zero energy gap by breaking the inversion symmetry between the two layers usin…
