In doping and post-treatment effect on holographic properties in In:Ce:Cu:LiNbO3 crystal，张涛，徐玉恒，A series of triply-doped In:Ce:Cu:LiNbO3 crystals with a varying level of In doping were grown by Czochraski technique in air atmosphere, and some samples
Influence of Titanium Doping on the Structure and Morphology of MgO prepared by Coprecipitation Method，王维，乔学亮，Ti-doped magnesium oxide powders were prepared by a chemical coprecipitation technique using magnesium nitrate hexahydrate and titanium tetr
In this work, a methodology to analyze trapping mechanism of As auto-doping has been presented in the epitaxial.diode array and CMOS integration. With a temperature-pressure optimization in three-step silicon epitaxial.growth being proposed, As trapp
We have synthesized a series of high quality EuTi(1-x)Cr(x)O(3) ( x = 0.0, 0.02, and 0.04) nanoparticles by simple sol-gel technique. The averaged grain size of these obtained nanoparticles displays no obvious change with Cr-doping and is about 100 n
Germanium doping in silica can be used as a method for nonlinearity enhancement. Properties of the enhanced nonlinearity in photonic crystal fiber (PCF) with a GeO2-doped core are investigated theoretically by using all-vector finite element method.
This paper reports on significantly improved efficiency of InAs/GaAs quantum dot (QD) solar cells by directly doping Si into InAs QDs during the QD growth. The devices which contain five stacked QDs in their i-regions were grown using molecular beam
The upconversion luminescences of YAlO3:Er3+ phosphor co-doping with different Gd3+ concentrations are investigated under the excitation of 980- and 532-nm diode lasers. A near ultraviolet upconversion emission at 410 nm is observed in YAlO3 under 53
