| 9 | InGaN micro-light-emitting diodes monolithically grown on Si:achieving ultra-stable operation through polarization and strain engineering显示文摘Micro or submicron scale light-emitting diodes(μLEDs)have been extensively studied recently as the next-generation display technology.It is desired that μLEDs exhibit high stability and efficiency,submicron pixel size,and potential monolithic integration with Si-based complementary metal-oxide-semiconductor(CMOS)electronics.Achieving such uLEDs,however,has remained a daunting challenge.The polar nature of Ill-nitrides causes severe wavelength/color instability with varying carrier concentrations in the active region.The etching-induced surface damages and poor material quality of high indium composition InGaN quantum wells(QWs)severely deteriorate the performance of uLEDs,particularly those emitting in the green/red wavelength.Here we report,for the first time,μLEDs grown directly on Si with submicron lateral dimensions.The μLEDs feature ultra-stable,bright green emission with negligible quantum-confined Stark effect(QCSE).Detailed elemental mapping and numerical calculations show that the QCSE is screened by introducing polarization doping in the active region,which consists of InGaN/AlGaN QWs surrounded by an AlGaN/GaN shell with a negative Al composition gradient along the c-axis.In comparison with conventional GaN barriers,AlGaN barriers are shown to effectively compensate for the tensile strain within the active region,which significantly reduces the strain distribution and results in enhanced indium incorporation without compromising the material quality.This study provides new insights and a viable path for the design,fabrication,and integration of high-performance μLEDs on Si for a broad range of applications in on-chip optical communication and emerging augmented reality/mixed reality devices,and so on. | Yuanpeng Wu Yixin Xiao Ishtiaque Navid Kai Sun Yakshita Malhotra Ping Wang Ding Wang Yuanxiang Xu Ayush Pandey Maddaka Reddeppa Walter Shin Jiangnan Liu Jungwook Min Zetian Mi | 2022 | Light(Science & Applications)2022，11，10： | 0 |
| 10 | Differential impacts of adult trees on offspring and non-offspring recruits in a subtropical forest显示文摘An important mechanism promoting species coexistence is conspecific negative density dependence(CNDD),which inhibits conspecific neighbors by accumulating host-specific enemies near adult trees.Natural enemies may be genotype-specific and regulate offspring dynamics more strongly than non-offspring,which is often neglected due to the difficulty in ascertaining genetic relatedness.Here,we investigated whether offspring and non-offspring of a dominant species,Castanopsis eyrei,suffered from different strength of CNDD based on parentage assignment in a subtropical forest.We found decreased recruitment efficiency(proxy of survival probability)of offspring compared with non-offspring near adult trees during the seedling-sapling transition,suggesting genotype-dependent interactions drive tree demographic dynamics.Furthermore,the genetic similarity between individuals of same cohort decreased in late life history stages,indicating genetic-relatedness-dependent tree mortality throughout ontogeny.Our results demonstrate that within-species genetic relatedness significantly affects the strength of CNDD,implying genotype-specific natural enemies may contribute to population dynamics in natural forests. | Fang Wang Xiangcheng Mi Lei Chen Wubing Xu Walter Durka Nathan GSwenson Daniel JJohnson Samantha JWorthy Jianhua Xue Yan Zhu Bernhard Schmid Yu Liang Keping Ma | 2022 | Science China(Life Sciences)2022，65，10： | 0 |
