Hydrogenated amorphous silicon (a-Si:H) thin films have been considered for use in solar cell applications because of their significantly reduced cost compared to crystalline bulk silicon, however, their overall efficiency and stability are less than that of their bulk crystalline counterparts. Limited work has been performed on simultaneously solving the efficiency and stab...$28.00

Transparent conductive thin films (TCO) are widely used in the manufacturing of both flat panel displays and solar cells two market segments which are rapidly developing in the last decade. TCO thin films allow the electrical contacting of large active areas that is largely transparent in the visible spectral range.

Abstract: In this paper, we want to show the photoluminescence(PL) properties, electric properties and surface morphology of ZnO thin films which were irradiated by KrF excimer laser under different atmospheres (air, oxygen, nitrogen). After laser irradiation(no matter whatever atmosphere), compared with the as-prepared thin films, the irradiated thin films exhibit a series of visible properties: resistivity is decreased by three orders of magnitude, carrier concentration is increased...$28.00

A picosecond pulsed laser has demonstrated successful selective ablation of different thin film layers from multilayer stacks on flexible substrates allowing structuring of large area flexible organic electronic devices. These thin film layers are extremely thin and sensitive to thermal damage, so the ultrashort pulse duration combined with the flexibility to use infrared, gree...$28.00

The sensitivity required for optical fiber sensors such as fiber Bragg gratings (FBG) is highly dependent on applications, environment of use and the magnitude of measured physical parameters. Such sensitivity dependencies are more complicated if FBGs are embedded in metallic structures using laser-assisted additive ma...$28.00

This work describes the fabrication of silver/polymeric matrix conductive tracks on a low density polyethylene (LDPE) structure using laser direct writing technology. This has enabled the direct writing of 3-dimensional small circuit boards when discrete electronic components are included into the writing process. In this project, the laser beam was reconstructed by diffractive optica...$28.00
