We report on the experimental evidence of a fully ballistic nano-FET with a voltage gain higher than 1 which is based on a 1D quantum ballistic conductor. In such a FET, the transconductance and the output conductance are basically modulated by the 1D subbands and the experimental results can theoretically be explained based on the Landauer-Buttiker formalism and the Buttiker model of the saddle-point...
Summary form only given. In this talk, we show that properly designed 1D-QB conductor can actually lead to voltage-gain. Conceptually, the electric conduction in the 1D-QB conductor can be described by the Landauer-Buttiker formalism in terms of the relative positions between the 1D sub-bands (SB), the electrochemical potential of the source reservoir and that of the drain reservoir, and the transmission...
We present a comprehensive experimental study of mesoscopic noise in a GaAs quantum point contact. In agreement with existing theory, we find that the measured noise power is strongly reduced from the full shot noise 2eI (I is the time-averaged current) expected for completely uncorrelated electron transport. Study of the temperature dependence of the noise clearly demonstrates the transition from...
