Abstract:The electric behaviour of the quasi-one-dimensional charge density wave (CDW) compound K0,Jfo03 is investigated at liquid-helium temperatures. At a threshold voltage, an abrupt increase in the conductivity takes place. The onset of this transition in conductivity is marked by a hysteresis. In the low-conducting branch of this hysteresis an intermittently spiking current signal in time domain has been found. l/f" noise and a power law scaling of the firing and waiting times as well as for spike sizes are charac… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
