Greener Spray CVD Process with Water Solution to Fabricate Transparent IR-Shielding Films on Glass Windows

CVD Growth and Characterization of B-SiC for IR Windows

The status of transparent SiC for short wave (3–5 μm) windows and domes is reviewed. Transparent β-SiC was fabricated by the pyrolysis of methyltrichlorosilane in the presence of excess H2 and argon in a hot wall, chemical vapor deposition reactor. Characterization of the material indicates that the transparent SiC is a theoretically dense, void free, highly pure (99.9996%) cubic material posse...

Synthesis of Solution-Processed Cu2ZnSnSe4 Thin Films on Transparent Conducting Oxide Glass Substrates

Cu2ZnSnSe4 (CZTSe) thin films were synthesized on transparent conducting oxide glass substrates via a simple, non-toxic, and low-cost process using a precursor solution paste. A three-step heating process (oxidation, sulfurization, and selenization) was employed to synthesize a CZTSe thin film as an absorber layer for use in thin-film solar cells. In particular, we focused on the effects of sul...

Growth of Heteroepitaxial CVD Diamond Films on Ir/YSZ/Si(001) for Detector Applications

For future particle accelerator experiments, e.g. at FAIR, we are developing novel, advanced diamond sensors grown by chemical vapour deposition (CVD), capable on one hand of replacing the commonly used silicon tracking devices and being on the other hand an advantageous alternative to polycrystalline or single-crystal diamond sensors used so far in beam diagnostics and timing applications. By ...

Transparent Ferroelectric Capacitors on Glass

We deposited transparent ferroelectric lead zirconate titanate thin films on fused silica and contacted them via Al-doped zinc oxide (AZO) transparent electrodes with an interdigitated electrode (IDE) design. These layers, together with a TiO2 buffer layer on the fused silica substrate, are highly transparent (>60% in the visible optical range). Fully crystallized Pb(Zr0.52Ti0.48)O3 (PZT) films...
