Phosphorus-induced lattice dynamic behaviors in ZnO:P epilayers grown by the metalorganic chemical vapor deposition technique have been studied using Raman scattering method. Additional modes around 504, 520, 655, and 866cm−1 are attributed to disorder-activated due breakdown of translational symmetry P doping, well supported reported ab initio calculations dynamics w-ZnO. Two 364 478cm−1 assigned local vibrational Zn–P P–O pairs, respectively. The correlation transport properties...

With the increasing need to apply modern software techniques hardware design, Verilog, most popular Hardware Description Language (HDL), plays an infrastructure role. However, Verilog has several semantic pitfalls that often confuse and developers. Although prior research on formal semantics for exists, it is not comprehensive fully addressed these issues. In this work, we present a novel scheme inspired by previous work defining core languages like JavaScript Python. Specifically, define of...

Abstract Temperature dependence of the Raman spectra ester ferroelectric liquid crystal MBOPDOB are examined in all four phases. The 15 and 49 cm−1 modes vanish at crystal-smectic C* transition point without any detectable frequency shift, which is classified into an order-disorder category. All results include small heat, 93cm−1 mode spontaneous polarization continuously going through point, 1178 1710 being transferred to 1166 1738 cm−1, respectively, manifest a continuous second-order for...
