Electromagnetic absorption in transparent conducting films

Electromagnetic absorption in transparent conducting films

In this article we calculate the skin depth of indium tin oxide ~ITO! films ~and related materials! as a result of free electron absorption within the visible spectrum using the simple Drude model. We also discuss the consequences of finite skin depth for the transparency of current spreading layers for light emitting diode ~LED! applications. Low sheet resistances are highly desirable for thes...

Microwave Characterization of Transparent Conducting Films

The high frequency conductivity of thin metallic and graphitic nano-films attracts interest due to many potential applications in spin electronics, electromagnetic shielding, flexible antennas, displays, and in solar cells. Surface morphology of thin conducting nano-films typically consists of an isolated clustering structure, which can evolve into a conducting percolated network [1]. The high ...

Transparent conducting films from NbSe3 nanowires.

We have developed methods to disperse and partially size separate NbSe(3) nanowires in aqueous surfactant solutions. These dispersions can easily be formed into thin films. Optical and electrical studies show these films to display sheet resistances and transmittances ranging from (460 Ω/□, 22%) to (12 kΩ/□, 79%) depending on thickness. For thicker films, we measured the transparent conducting ...

Fabrication of graphene films with high transparent conducting characteristics

We present a study on the transparent conducting characteristics of graphene-based films prepared by means of rapid chemical vapor deposition. The graphene films were grown on quartz slides with a CH4/Ar mixed gas under a constant flow at 950°C and then annealed at 1,000°C. It was found that the graphene films present excellent electrical conductivity with high transparency. The conductivity is...
