Thermochromic VO2 films by thermal oxidation of vanadium in SO2
TL;DR: In this paper, a two-step procedure was used to deposit metallic vanadium, and such layers were subsequently oxidized in SO 2 at a temperature in the 600-650°C range.

Analysis of an attenuator artifact in an experimental attack by gunn–allison–abbott against the kirchhoff-law– johnson-noise (kljn) secure key exchange system
TL;DR: In this paper, the authors show that an attenuator break the single Kirchhoffloop into two coupled loops, which is an incorrect operation since the single loop is essential for the security in the KLJN system, and hence GAA's asserted information leak is trivial.
Journal ArticleDOI
Enhanced Usage of Keys Obtained by Physical, Unconditionally Secure Distributions
TL;DR: In this article, an almost-one-time-pad-based communication protocol with an unconditionally secure physical key of finite length is proposed, where the physical key is not used for data encryption but is employed in order to generate and share a new software-based key without any known-plain-text component.
Journal ArticleDOI
Electrical and optical properties of sputter deposited tin doped indium oxide thin films with silver additive
TL;DR: In this paper, the real part of the refractive index of ITO was determined from ellipsometry data, applying a model combining a Drude and a Lorentz term.
Journal ArticleDOI
Electrochromic Ni Oxide Films studied by Magnetic Measurements
TL;DR: In this paper, magnetic measurements of Ni-oxide-based thin films were performed at low temperatures using SQUID technology, and they exhibited a well-defined Curie Weiss behavior with a transition temperature that was depressed by proton extraction.
