Did you know?
WebThe topcoat thickness of thermal barrier coating (TBC) samples was measured using terahertz (THz) waves. The index of refraction of yttria-stabilized zirconia (YSZ), which is the topcoat material, is necessary to obtain the topcoat thickness from time domain reectometry. ... The results showed that THz waves are eective for high-resolution ... WebTerahertz measurements were made over a two-dimensional area and therefore a map of thickness as a function of position is generated. The histogram clearly indicates distinctly …

WebTerahertz coating thickness measurement is suitable for many different applications. The method has great advantages, especially, in the analysis of complex multilayer systems, … WebThe present work gives an insight into some key measurement and signal processing considerations in terahertz pulsed imaging (TPI). TPI is increasingly used for the measurement of the spatial variation of coating thickness on coated solid dosage forms.
WebHowever, the terahertz (THz) and ultrafast responses of the 2D halide perovskites are seldom studied, limiting the developments and applications of tunable terahertz devices based on 2D perovskites. Here, 2D R-P type (PEA)2(MA)2Pb3I10 perovskite films are fabricated on quartz substrates by a one-step spin-coating process to study their THz and …
