Graphene Frequency Multipliers [PDF]

IEEE Electron Device Letters, 2009
In this letter, the ambipolar transport properties of graphene flakes have been used to fabricate full-wave signal rectifiers and frequency-doubling devices. By correctly biasing an ambipolar graphene field-effect transistor in common-source configuration, a sinusoidal voltage applied to the transistor gate is rectified at the drain electrode.

CLINOTRON AS A FREQUENCY MULTIPLIER IN THE SUB-MM WAVEBAND (λ= 0.935 mm) [PDF]

Радиофизика и электроника, 2015
In comparison to backward wave oscillator (BWO) of O-type, requirements to the quality of electron beams are weakened in the frequency multipliers. Therefore, frequency multipliers may have a considerable perspective for mastering the sub-millimetre ...
