Pyroelectric energy harvesting is one of the more recent and promising solid-state approaches for directly converting time-dependent temperature fluctuations into electric energy. Conventional printing technologies can offer many advantages production pyroelectric thin-film-based devices, such as low cost, temperature, use flexible substrates shaping at same time deposition. Nevertheless, some ...

As a novel application of silicon-based integrated optics, results from a proposed compact Mach-Zehnder interferometer are presented. The deposition of a ZnO thin-film transducer upon the reference arm of the interferometer transforms this optically passive device into a device with active sinusoidal phase modulation.

A thin film lead zirconate titanate, Pb(Zr,Ti)O3 (PZT), MEMS power generating device is developed. It is designed to resonate at specific frequencies from an external vibrational energy source, thereby creating electrical energy via the piezoelectric effect. Our cantilever device i t 2 f 1 d r ©

Distributed sensing of gas-phase chemicals is a promising application for mesoporous materials when combined with highly sensitive miniaturized gas sensors. We present a direct application of a mesoporous silica thin film on a highly sensitive miniaturized resonant chemical sensor with a mass sensitivity at the zeptogram scale for relative humidity and CO(2) detection. Using mesoporous silica t...

The purpose of this paper is to model the performance of thin film amorphous silicon (a-Si:H) solar cells under AM1.5G spectral conditions. In this work, a numerical model for the investigation of thin film amorphous silicon p-i-n cells has been developed. The light absorption is treated as a non-uniform, exponentially decaying function, which also allows to use spectral ensembles to be investi...

A Silver (Ag) thin film is introduced as a template and doping source for vertically aligned p–type ZnO nanorods. ZnO nanorods were grown using an ammonium hydroxide based hydrothermal process. During the hydrothermal process, the Ag thin film was dissolved to generate Ag ions in the solution. The Ag ions can contribute to doping in the wurzite structure of ZnO and the (111) grain of Ag thin fi...
