Semiconductors

Semiconductors are materials that have a small electronic bandgap. This bandgap prevents current from flowing at absolute zero, but thermally excited charge carriers can begin to flow at higher temperatures. Semiconductors, notably silicon, are at the heart of the modern microelectronics industry, and also have applications in light sources and detectors.

    Through stochastic resonance, noise-driven fluctuations make an otherwise weak periodic signal accessible. Experiments have now reported quantum stochastic resonance, which arises from intrinsic quantum fluctuations rather than external noise.

    Despite an enormous number of nanopores that could, in principle, be formed in atomically thin materials, advanced modelling reveals that in typical experiments rather limited ensembles of most likely nanopores should be observed.
