Four prisoners attacked one of the officers and hijacked his car, which they drove towards the external gate.
Similar to LeuBAT, the DAT-bound TCA drug cannot progress through the substrate pore as a substrate would because its binding extends into the region of the external gate, preventing gate closure.
We also show that the possibility to tune the doping level of graphene by an external gate voltage allows one to maximize the radiated EFISHG power at ℏω= EF, which may be of practical interest for the designs of the NLO devices based on employing a SHG-signal.
It can also be varied electrostatically by an external gate in a gated-wire configuration.
The floating gate is embedded in the gate dielectric layer as a thin film or in discrete nanoparticle form [29]. OFETs normally operate in the accumulation mode; electrons or holes are induced by the application of an external gate electric field, negative or positive gate voltage (Vg), respectively.
However, it has been found that the application of perpendicular electric fields produced by external gates deposited on the BLG surface can induce a gap in the spectrum.
In particular, the surface charge density, namely chemical potential, can be actively modified by chemical doping or external gate voltage, thus giving rise to dramatic changes in the optical properties [20].
Particularly, the surface conductivity of graphene can be dynamically tuned by chemical potential via external gate voltage or chemical doping [24, 25], which makes graphene to be a promising candidate for designing tunable PIT while the geometrical parameters are fixed.
The Rashba SO interaction can be tuned by the external electric field, or the gate voltage [5 7].
Both 'passive' hetero-structures as well as surface-induced effects by external gating are discussed.
