Big Data Analysis, Design, Effect Fabrication, and Properties Analysis of SiO/Cr/SiO Colored Solar Selective Absorbers with High PTCE and Chromaticity for Building Applications.

In today's era of rapid computing, advanced big data analytics enables precise results and efficient trend analysis. By leveraging these tools, the influence of various film thicknesses of Colored Solar Selective Absorbers (CSSAs) on solar absorption efficiency (α) and chromaticity was investigated. A clear and visually informative Chromaticity Coordinate Distribution (CCD) versus α diagram was constructed within the CIE xy chromaticity diagram, establishing a correlation between chromaticity and α.

Application of an alternating phase-shifting mask design method to near-field photolithography for fabricating more than 2 GHz SAW devices.

We use an alternating phase-shifting mask design method (APSMDM) to design and fabricate a specially designed surface acoustic wave (SAW) filter mold that has a linewidth pattern of only 5 microm (not small). A basic SAW filter mold [having a general interdigital transducer (IDT) pattern] also is fabricated for comparison. A near-field phase shift lithographic (NFPSL) process is applied in the fabrication of the narrow gap SAW devices, during which process the narrow gaps and short optical distance (SOD) electrodes are derived.
