Problems solved by technology

Local irregularities on the metal surface are possible reasons for the presence of high-intensity electric fields, but only locally, and most of the emissions due to electric field effects are likely to come from these regions

Embodiment Construction

[0072] refer to Image 6 , an electrochromic device based on permeable metal thin films according to the invention, characterized by a "flat" structure, the electrochromic device comprises the following components:

[0073] 1. Transparent glass substrate 13,

[0074] 2. connected to the two side electrodes 12 of the power supply 14,

[0075] 3. the active layer 10 of nanostructured metallic material at the infiltration level, and

[0076] 4. A transparent protective layer 11 .

[0077] transparent substrate

[0078] The substrates used are common glass prepared with an ultrasonic cleaning process or alternative plastic materials such as polycarbonate, methacrylate, CR39, etc.

[0079] Therefore, transparent substrates covered with particularly expensive coatings, such as ITO-coated glass, are not required.

[0080] side electrode

[0081] Two electrodes are placed in contact with the two lateral surfaces of the infiltrated metal structure, consisting of a continuous meta...

Abstract

Bidimensional or three-dimensional, single-layer or multilayer nanostructure, whose electric conductivity ss in the total structure has a highly non-linear behavior due to local tunnel effect between adjacent clusters, and it can be varied at will by varying the voltage applied to the electrodes.

Description

technical field [0001] This invention relates to infiltrated metal films. [0002] An infiltrated metal film is a two-dimensional or three-dimensional nanostructured metal structure comprising metal clusters interconnected with each other or coupled due to tunneling to ensure electrical conduction. The structures are usually obtained by evaporation processes (thermal or electron beam), or by sputtering processes by chemical vapor deposition or ultrasonic cluster beams via pulsed microplasma sources. [0003] The electrical and electronic properties of the film indicate that the conductivity σ of the system as a whole is not constant, but varies with the voltage applied across the film's terminals. The relatively simple control of the conductivity σ of discontinuous metal films makes this system based on the electrochromic effect interesting for applications. By this we mean changes in optical properties, especially changes in absorption, transmittance and reflectance, and ch...
