Compounds of isotactic polypropylene (iPP) and beta-nucleating agent were used to investigate the relationship between the development of beta phase and molecular weight in iPP under quiescent crystallization conditions by using wide angle X-ray diffraction and differential scanning calorimetry techniques. In all cases
the dependency of the formation of beta phase in iPP on molecular weight of iPP at a defined crystallization temperature range was found. The iPP with high molecular weight possessed a wide range of crystallization temperature in inducing rich beta phase. However
poor or even no beta phase was obtained for the samples with low molecular weight in the same range. In addition
an upper critical crystallization temperature of producing dominant beta phase was found at 125 degrees C. Beyond this temperature
a phenomenon of prevailing alpha phase became obvious. (C) 2014 Wiley Periodicals

Hexagonal MgxZn1-xO alloy layers with 0 &le 0.3 have been grown by plasma-assisted molecular beam epitaxy on sapphire (006) and Si (111) substrates. Their crystal structures are characterized by x-ray diffraction spectroscopy. The nonresonant and resonant Raman spectra were measured using 488 nm line from Ar+ laser
and 325 nm line from He-Cd laser by backscattering geometry. Four Raman modes (E2 high
LO
TO
multiphonon processes) were observed in the nonresonant Raman spectra of hexagonal MgxZn1-xO with different Mg contents. The optical phonon frequencies were found to display one-mode behaviour for all the samples since no separate ZnO- and MgO-like modes were observed. The long-wavelength frequencies of ZnO-like optical phonons measured in the resonant Raman spectra can be expressed as linear functions of x. These behaviours can be explained within a modified random-element-isodisplacement model (MREI). 2006 WILEY-VCH Verlag GmbH Co. KGaA.

ZnO/GaN p-i-n heterojunctions light emitting diodes were fabricated by plasma-assisted molecular beam epitaxy. We make use of high resistivity of nitrogen doped ZnO to fabricate n-ZnO/i-ZnO/p-GaN heterojunction light emitting diode. The emission of i-ZnO was obtained due to the limitation effect of i-ZnO on electrons and holes. Moreover
n-ZnO/i-MgO/p-GaN heterojunction light emitting diode was also fabricated. The limitation effect on electrons is increased in this heterojunction. The bright ultraviolet electroluminescence at 382 nm originating from the ZnO layer was observed in the room temperature electroluminescence spectrum. We hope to realize the stimulated emission of ZnO using these heterojunctions by the improvement of crystal quality and the optimization of device structure. 2006 WILEY-VCH Verlag GmbH Co. KGaA.
