Journal ArticleDOI
Galvanostatic Ion Detrapping Rejuvenates Oxide Thin Films.
Miguel A Arvizu,Rui-Tao Wen,Daniel Primetzhofer,Jolanta E. Klemberg-Sapieha,Ludvik Martinu,Gunnar A. Niklasson,Claes-Göran Granqvist +6 more
TL;DR: Time-of-flight elastic recoil detection analysis (ToF-ERDA) documented pronounced Li(+) trapping associated with the degradation of the EC properties and, importantly, thatLi(+) detrapping, caused by a weak constant current drawn through the film for some time, could recover the original EC performance.
Journal ArticleDOI
Ion Trapping and Detrapping in Amorphous Tungsten Oxide Thin Films Observed by Real-Time Electro-Optical Monitoring
TL;DR: In amorphous electrode materials, a detailed knowledge of Li-ion intercalation is hamper energy saving and storage as mentioned in this paper, which relies on ion exchange between electrodes and electrolytes.
Journal ArticleDOI
Comparison of Classical and Fluctuation-Enhanced Gas Sensing with PdxWO3 Nanoparticle Films
Jesper Ederth,Jesper Ederth,Janusz Smulko,Janusz Smulko,Laszlo B. Kish,Peter Heszler,Peter Heszler,Claes-Göran Granqvist +7 more
TL;DR: In this paper, the stochastic signal component (fluctuationenhanced signal) originating from resistance fluctuations and the dc resistance (classical sensor signal) were measured during exposure to ethanol and hydrogen gas.
Journal ArticleDOI
On the security of the Kirchhoff-law---Johnson-noise (KLJN) communicator
TL;DR: In this article, a simple and general proof is given for the information theoretic security of the Kirchhoff-law---Johnson-noise key exchange system under practical conditions, which is guaranteed by the continuity of functions describing classical physical linear, as well as stable nonlinear, systems.
Journal ArticleDOI
Low-temperature synthesis of thermochromic vanadium dioxide thin films by reactive high power impulse magnetron sputtering
TL;DR: In this article, high power impulse magnetron sputtering (HiPIMS) discharges were used to synthesize VO 2 thin films from highly ionized fluxes of depositing species.
