Development and Analysis of Tungsten Thin film Coating for Solar Absorption

Role of Magnetic Field and Bias Configuration on Hipims Deposition of W Films

“…For instance, W films have been studied for microelectronics industry [1,2], x-ray lithography [3] and surface acoustic wave sensors production [4]. Furthermore, they are also exploited in the energy sector [5][6][7][8]. In this respect, W is a key material for the development of magnetic confinement fusion which still presents several aspects to be addressed as, for example, the so-called plasma-wall interaction (PWI).…”

Ion irradiation-induced localized stress relaxation in W thin film revealed by cross-sectional X-ray nanodiffraction

“…Polycrystalline tungsten thin films have been used in microelectronic and space components, optical and sensor applications due to their particular physical properties like high melting point of ~3700 K, good thermal conductivity, high solar wind absorption and diffusion barrier characteristics [2][4] [5][6] [7] [8]. The films prepared by physical and chemical vapor deposition techniques (PVD, CVD) usually exhibit tensile or compressive residual stresses, which may enhance the functional properties of the components or result in degradation phenomena like cracking and loss of adhesion.…”

Electrochromic Metamaterials of Metal–Dielectric Stacks for Multicolor Displays with High Color Purity

“…The proposed high-color-purity MMDM-structured EC electrode is composed of a metal/dielectric film stack. WO 3 , the most widely used inorganic EC material, is selected as the dielectric material because its optical constant is easy to adjust under electrochemical action. , Tungsten (W) is selected as the metal layer because of its high electrochemical stability and weak refractive index dispersion in the visible region Figure a illustrates the schematic of light propagation in a three-pair periodic W–WO 3 MMDM under vertical illumination.…”

“…28,29 Tungsten (W) is selected as the metal layer because of its high electrochemical stability and weak refractive index dispersion in the visible region. 30 Figure 1a illustrates the schematic of light propagation in a three-pair periodic W−WO 3 MMDM under vertical illumination. In contrast to the F−P resonant modes, which are achieved when the phase condition is satisfied, MMDMs support the propagation of incident light in two ways simultaneously, thus enhancing light−matter interactions at the nanoscale.…”
