Emission Mechanism of High Al-content AlGaN Multiple Quantum Wells

紫外LED的发光功率和效率还远不能令人们满意,波长短于300 nm的深紫外LED的发光效率普遍较低。厘清高Al组分Al Ga N多量子阱结构的发光机制将有利于探索改善深紫外LED的发光效率的新途径、新方法。为此,本文通过金属有机气相外延技术外延生长了表面平整、界面清晰可辨且陡峭的高Al组分AlGa N多量子阱结构材料,并对其进行变温光致发光谱测试,结合数值计算,深入探讨了Al Ga N量子阱的发光机制。研究表明,量子阱中具有很强的局域化效应,其发光和局域激子的跳跃息息相关,而发光的猝灭则与局域激子的解局域以及位错引起的非辐射复合有关。The quantum efficiency of deep UV light emitting diodes( LED) drops dramatically with the increasing of Al content. Understanding the emission mechanism of high Al-content Al Ga N multiple quantum wells( MQW) is the one of the most important objects for improving the quantum efficiency of deep UV LED. In this work,high Al-content Al Ga N MQW structure with atomically flat hetero-interfaces was grown and characterized by photoluminescence( PL) measurements at different temperatures. The results indicate that there is a strong exciton-localization effect in the MQW structure and the emission is closely related to the hopping of the excitons. Due to the exciton delocalization and nonradiative recombination at defects,the PL intensity is strongly quenched at high temperatures.“973”国家重点基础研究发展计划(2012CB619300);; “863”国家高技术研究发展计划(2014AA032608);; 国家自然科学基金(U1405253;61227009;11204254;11404271);; 福建省自然科学基金(2015J01028)资助项

Local Sensitivity and Its Stationarity Analysis for Urban Rainfall Runoff Modelling

基于MOrrIS筛选法,在厦门城市小流域采用8场实测降雨数据对城市降雨径流模型SWMM的水文水力模块进行局部灵敏度及其稳定性分析.结果表明,ArEA、%IMPErV和dSTOrE-IMPErV是影响降雨总径流量和流量峰值最灵敏的参数.对于总径流量,ArEA、%IMPErV和dSTOrE-IMPErV的灵敏度分别为0.46~1.0、0.61~1.0和-0.050~-5.9;而对于流量峰值,它们的灵敏度分别为0.48~0.89、0.59~0.83和0~-9.6.其中降雨强度最小的场次降雨的各个参数降雨总径流量和流量峰值的灵敏度都最大,而降雨强度较大的场次降雨的总径流量和流量峰值的灵敏度都较小.不同场次降雨模型参数的灵敏度分析具有很大的差异性,但%zErO-IMPErV对总径流量和流量峰值模拟输出影响的稳定性最小,表现在变异度最大,高达221.24%和228.10%,而COnduCTIVITy参数稳定性最大,变异系数都为0.Sensitivity analysis of urban-runoff simulation is a crucial procedure for parameter identification and uncertainty analysis.Local sensitivity analysis using Morris screening method was carried out for urban rainfall runoff modelling based on Storm Water Management Model(SWMM).The results showed that Area,% Imperv and Dstore-Imperv are the most sensitive parameters for both total runoff volume and peak flow.Concerning total runoff volume,the sensitive indices of Area,% Imperv and Dstore-Imperv were 0.46-1.0,0.61-1.0,-0.050--5.9,respectively;while with respect to peak runoff,they were 0.48-0.89,0.59-0.83,0--9.6,respectively.In comparison,the most sensitive indices(Morris) for all parameters with regard to total runoff volume and peak flow appeared in the rainfall event with least rainfall;and less sensitive indices happened in the rainfall events with heavier rainfall.Furthermore,there is considerable variability in sensitive indices for each rainfall event.% Zero-Imperv’s coefficient variations have the largest values among all parameters for total runoff volume and peak flow,namely 221.24% and 228.10%.On the contrary,the coefficient variations of conductivity among all parameters for both total runoff volume and peak flow are the smallest,namely 0.国家自然科学基金项目(50778098);福建省青年人才项目(2007F3093

在澳门与厦门分别选一分流制管道类型的绿地小流域开展降雨径流监测,以研究城市绿地降雨径流污染特征.结果表明,两城市绿地小流域降雨径流的主要污染物为COd、TP、nO3--n,其EMC平均值分别为165.77--60.48 Mg/l、0.96--0.44 Mg/l和7.16--1.18 Mg/l;两城市绿地的COd、TP、nO3--n污染负荷平均值分别为6.53--0.63 kg/HM2、0.037 5--0.004 7 kg/HM2和0.012 2--0.012 8 kg/HM2;绿地降雨径流污染物浓度峰值出现时间早于径流量峰值;城市绿地降雨径流初始冲刷效应不明显,厦门绿地小流域降雨径流COd、TSS、TP及nO3--n的ff30分别为36.26%、26.13%、28.13%和39.03%.基于多元回归分析结果表明,总降雨量和总径流量是影响绿地降雨径流污染初始冲刷效应的主要因素.A comparative study on characteristics of stormwater runoff from two urban lawn catchments in Macau(ELH) and Xiamen(PGH) with separated sewer system were conducted.The result obtained shows that COD,TP and(NO---_3-N) are the major pollutants with mean EMC of 165.77-60.48(mg/L),0.96-0.44(mg/L) and 7.16-1.18(mg/L),respectively,and the mean values of pollutants loads of COD,TP and(NO---_3-N) from study lawn catchments are 6.53-0.63(kg/hm--2),(0.037?5)-(0.004?7)(kg/hm--2) and(0.012?2)-(0.012?8)(kg/hm--2),respectively.Peak values of major pollutant concentrations usually precede the flow peak.First flush effect of rainfall runoff from two study catchments is no obvious,which can be reflected by the low mean value of FF_(30) of TSS,COD,TP and(NO---_3-N),with 36.26%,26.13%,28.13% and 39.03%,respectively.Based on multivariate statistical analysis,first flush effect from urban lawn rainfall runoff is greatly influenced by total rainfall amount(T_r) and total runoff volume(V).国家自然科学基金项目(50778098);福建省青年人才项目(2007F3093
