... an underlying layer of pure silicon. This transparent substrate acted as the gate electrode. The whole system was cooled to 45 kelvins (379 degrees Fahrenheit below zero). "To measure ...

... have performed the first scanning tunneling spectroscopy of graphene flakes equipped with a "gate" electrode. The result is the latest in a series of surprising insights into the electronic behavior ...

The first scanning tunneling spectroscopy of graphene flakes equipped with a "gate" electrode has found an unexpected gap-like feature in the energy spectrum of electrons tunneling into graphene's ...

... resistive state by means of an external electric field, controlled by applying a voltage and using the third (gate) electrode. Circuits built from such devices would be much faster and use less power ...

... substrates and then transferred to glass or PET substrates with pre-patterned indium-tin oxide (ITO) gate electrodes, followed by patterning of transparent source and drain ...

... 'box' which traps a controllable number of electrons. This box is coupled to one or more gate electrodes with which the number of electrons on the dot can be varied. The researchers developed a new ...

... applied, continuously tunable electrical field. But when such a field is applied with a single gate (electrode), the bilayer becomes insulating only at temperatures below one degree Kelvin, near ...

... the material's two-dimensional surface by means of a third, gate electrode. Plots of voltage vs. capacitance can be seen in fig1. In Tao's experiments, graphene's ability to store charge ...
