A room temperature single-electron transistor based on the single cluster molecule has been demonstrated for the first time. Scanning tunneling microscope tip was used to study the transport via single carboran cluster molecule 1,7-(CH 3 ) 2 -1,2-C 2 B 10 H 9 Tl(OCOCF 3 ) 2 incorporated into the Langmuir-Blodgett monolayer of the stearic acid. DC I-V curves at 300 K showed well pronounced Coulomb staircase, and the current could be controlled by a lithographically fabricated gold gate electrode. 73.40.Gk, 61.16.Ch, 36.40.Cg Typeset using REVT E X 1
Complex regimes arising after the loss of stability of a viscous fluid with radial flow and radial temperature gradient between two heated rotating permeable cylinders are investigated in a small neighborhood of the point of intersection of neutral curves of monotonic axisymmetric and oscillatory three-dimensional instabilities. Since by the linear theory we can form a judgment only of the first loss of instability, the development of complex flows is investigated by nonlinear analysis, which makes it possible to detect transitions with generation of both quasiperiodic oscillations and chaotic regimes.
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.
