| 1 | Infuence of Substrate Temperature on Stress and Morphology Characteristics of Co Doped ZnO Films Prepared by Laser-Molecular Beam Epitaxy显示文摘Zn1exCox O(x 0.05) thin films are deposited on sapphire(0001) substrates by laser-molecular beam epitaxy technique at different substrate temperatures. The structural, stress and morphology evolution features are investigated by means of X-ray diffraction and atomic force microscopy. The surface parameters of roughness exponent a, root mean square(RMS) roughness w and autocorrelation length x are calculated and the surface parameters are preliminarily analyzed. The values of a vary from 0.7 to 0.9. The RMS roughness w is less than 2.2 nm, and it increases with increasing T s from 300 to 400 C, and then decreases when T s is 500 C. The autocorrelation length x decreases monotonously with the increase in T s from 300 to 500 C, which indicates that the increase in T s restrains the spread of the surface fluctuations until T s is higher than 400 C. | Yunyan Liu Shanying Yang Gongxiang Wei Jiaoqing Pan Yuzhen Yuan Chuanfu Cheng | 2013 | Journal of Materials Science & Technology2013，29，12： | 3 |

| 4 | Review on Leaf Water Use Efficiency of Major Trees Species in Arid and Semi-Arid Area显示文摘The tree specie selection is the critical part in the process of vegetation restoration and reconstruction in arid and semi-arid areas.As a reliable indicator of drought resistance and water use characteristics of tree species,water use efficiency(WUE) has become a hotspot in the research on tree specie selection.This paper introduced the concept and correspondingly research method of leaf WUE and summarized the research progress of leaf WUE in terms of the variation in leaf WUE between species,positions in the canopy,and characteristics of temporal and spatial variation,its influence on environmental factors like illumination,moisture,temperature, CO2 and O3 concentrations.Furthermore,it put forward the problems currently existing in the research and prospected the trend of future research on leaf WUE. | Wang Yunni Xiong Wei Wang Yanhui Yu Pengtao Xu Lihong Zuo Haijun Cao Gongxiang Sun Hao | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
