We present a study of phonon modes and electron-phonon coupling in superconductor WP using angle-resolved polarized Raman spectroscopy. Seven out twelve Raman-active are detected, with frequencies good accordance by the first-principles calculations. analyze parallel- cross-polarized configurations ${\mathrm{A}}_{\mathrm{g}}$ ${\mathrm{B}}_{3\mathrm{g}}$ polarization- measurements. For observed seven modes, total parameter $\ensuremath{\lambda}$ is only about 0.07, which too small to achieve...
A diode-end-pumped passively Q-switched Nd:LuAG laser at 1442.6 nm was demonstrated with a V3+:YAG crystal as the saturable absorber. Under continuous-wave (CW) operation, maximum output power of 1.83 W obtained an absorbed pumping 11.1 W. The corresponding optical-to-optical conversion efficiency 16.5%. average 424 mW same power. pulse duration and repetition rate were 72 ns 17.4 kHz, respectively.
We present an optical study on high-quality and single-phase LiTi2O4 (LTO) superconductor thin films grown MgAl2O4 substrates by pulsed laser deposition. The near infrared (NIR) reflectivity is measured for samples with (001) (111) lattice orientations. temperature-induced metal-superconductor transition can be observed, the superconducting temperature both samples. find that NIR reflection experiment reflect rightly basic features of LTO films. Furthermore, results obtained from this simple...
We present an investigation on the intrinsic optical properties of superconducting FeSe thin films deposited CaF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> substrates. It is found that samples respond strongly to near-infrared (NIR) irradiation in different temperature regimes. Thus, we are able measure reflectivity in-plane (ab-plane) from room 5 K. A critical behavior near transition (T...
Hybrid millet Zhang and its parental cultivars were studied for their potassium (K) uptake accumulation characteristics related physiological mechanisms.Hydroponic culture was performed with two K levels (i.e., high low) set up.At level, hybrid showed heterobeltiosis in leaf content, it also had higher H + -ATPase activity, respiration rate, root oxidant activity influx rate than cultivars.All these lay the foundation of heterosis millet.At low a lower efflux cultivars, thus or content not...
Three phase three level neutral point clamped (NPC) rectifier is a popular topology for power converter front-ends to achieve controllable DC voltage. In this paper, its mathematical model analyzed and dual-loop control strategy adopted regulate both voltage input factor. Instead of space vector PWM, an improved multi-level carrier based PWM presented. The system developed on DSP FPGA employed generate the signals. effectiveness proposed scheme verified by experimental results.
The family of titanium oxide superconductors exhibits many intriguing phenomena comparable to cuprates and iron pnictides/chalcogenides, thus provides an ideal platform contrastively study the unconventional pairing mechanism high-temperature superconductors. Here, we successfully deposit superconducting Mg-Ti-O films on MgAl$_2$O$_4$ substrates with three principal orientations by ablating a MgTi$_2$O$_4$ target. Particularly, it is striking observed that single-crystalline film unintended...
