“…Recently topological materials have been emerged as a new class of quantum matter possessing conducting states with nontrivial properties, including those reflecting states which are topologically protected against scattering from defects and impurities as well as signatures of Majorana fermions [48,49]. It should be emphasized that shot noise represents a promising way to study topological materials and to detect the Majorana mode via noise measurements of the normal-superconducting nanowire structure [50]. Furthermore, authors of [51] have presented a method of obtaining information about Majorana lifetime and its energy splitting from current noise measurements when one of the MBSs couples to a dynamical channel system.…”

Nanowires (NWs) have recently emerged as a new class of materials demonstrating unique properties which may completely differ from their bulk counterparts. The main aim of this work is to give an overview of results on noise and fluctuation phenomena in NW-based structures. We emphasize that noise is one of the main parameters, which determines the characteristics of the device structures and sets the fundamental limits of the working principles and operation regimes of NWs as key electronic elements, including field-effect transistors (FETs). We review the studies focusing on the understanding of noise sources and the main application aspects of noise spectroscopy. Noise application aspects will provide information about the performance of core-shell NW structures, the gate-coupling effect and its advantages for detection of the useful signal with prospects to extract it from the noise level, random telegraph signal as a useful tool for enhanced sensitivity, novel components of noise reflecting dielectric polarization fluctuation processes and fluctuation phenomena as a sensitive tool for molecular charge dynamics in NW FETs. Moreover, noise spectroscopy assists understanding of electronic transport regimes and effects, transport peculiarities in topological materials and aspects reflecting Majorana bound states. Thus noise in NWs on the basis of Si, Ge, Si/Ge, GaAs, InAs, InGaAs, Au, GaAs/ AlGaAs, GaAsSb, SnO 2 , GaN, ZnO, CuO, In 2 O 3 and AlGaN/GaN materials reflects a great variety of phenomena and processes, information about their stability and reliability. It can be utilized for numerous different applications in nanoelectronics and bioelectronics.
