A dialogue of lately built experimental tools for noise learn in nanoscale digital units, performed by means of experts in delivery and stochastic phenomena in nanoscale physics. The technique defined is to create equipment for experimental observations of noise assets, their localization and their frequency spectrum, voltage-current and thermal dependences. Our present wisdom of size equipment for mesoscopic units is summarized to spot instructions for destiny study, relating to downscaling results.

The instructions for destiny learn into fluctuation phenomena in quantum dot and quantum twine units are special. Nanoscale digital units could be the easy parts for electronics of the twenty first century. From this perspective the signal-to-noise ratio is a crucial parameter for the machine program. because the noise can also be a high quality and reliability indicator, experimental tools could have a large software sooner or later.

In this case, 1/f noise is hidden in the RTS. These observations do not support the hypothesis of RTS noise as a fundamental source of the 1/f noise. Introduced as a Deus ex machina to circumvent a difficult, maybe a profound physical problem, the idea that RTS noise is the fundamental source of the 1/f noise is a non sequitur because, among others arguments, 1/f noise exists both in the absence and in the presence of the RTS noise. 3. A problem of topology: surface vs. bulk The idea that 1/f noise is a surface effect is a corollary of the McWhorter model.

The maximal value of shot noise Smax = 2eI corresponds to the random, uncorrelated transmission events and is referred as Poisson value of noise. Shot noise at zero temperature is always suppressed with respect to the Poisson value. The above considerations refer to non-interacting electrons. A topic of recent interest is whether for interacting electrons shot noise can exceed the Poisson value. One option is the following. Poissonian noise results from uncorrelated transfer of electrons (with the charge e).

Sci. 280 (1993) 106. 1/f SPECTRA AS A CONSEQUENCE OF THE RANDOMNESS OF VARIANCE G. com Abstract: It is a general conviction that any measured noise be stochastically continuous and weak stationary. Therefore, standard noise analysis uses the substitution of ensemble averages by time averages, and it considers likewise the autocorrelation function and the sample spectrum as an unbiased and complete characterization of the measured process.
