Rectification in Graphene Self-Switching Nanodiode Using Side Gates Doping

The electrical properties and rectification behavior of the graphene self-switching diodes by side gates doping with nitrogen and boron atoms were investigated using density functional tight-binding method. The devices gates doping changes the electrical conductivity of the side gates and the semiconductor channel nanoribbons. As a result, the threshold voltage value under the forward bias is s...

Electro-optical graphene plasmonic logic gates.

The versatile control of graphene's plasmonic modes via an external gate-voltage inspires us to design efficient electro-optical graphene plasmonic logic gates at the midinfrared wavelengths. We show that these devices are superior to the conventional optical logic gates because the former possess cut-off states and interferometric effects. Moreover, the designed six basic logic gates (i.e., NO...

Voltage-driven spintronic logic gates in graphene nanoribbons

Electronic devices lose efficacy due to quantum effect when the line-width of gate decreases to sub-10 nm. Spintronics overcome this bottleneck and logic gates are building blocks of integrated circuits. Thus, it is essential to control electronic transport of opposite spins for designing a spintronic logic gate, and spin-selective semiconductors are natural candidates such as zigzag graphene n...
