| 1 | 重庆市退耕还林工程实施的生态和经济效益分析显示文摘为了给进一步推动退耕还林工程的实施提供科学的理论依据,以西南地区重庆市为研究区域,通过收集退耕还林相关监测数据、重庆市历年统计年鉴资料和历年环境状况公报等,并结合野外参与式农户调查,对该区域退耕还林的生态和经济效益两个方面进行了分析与探讨。结果表明:退耕还林不仅明显提高植被覆盖率,也对水土保持、改善土壤质量状况、净化大气和固碳释氧起到积极作用。生态林在此次退耕还林中为主要林木类型,但经济林生长势和覆盖度整体上要好于生态林。乔灌混交林所占比例较低;退耕还林后,耕地面积减少,但粮食产量逐渐恢复到原有水平。人均收入显著增长,年均增长率达31.9%。林业产值也在逐年增加。退耕还林的实施对生态环境、当地经济兼具有促进作用,但相关部门还需进一步提高乔灌混交林的比例,并加强对生态林的管护。另外,采取有效措施来提高林业产值。 | 高磊 杨现坤 胡海珠 吕喜玺 侯国龙 Claudio Delang 王晓燕 陈方鑫 | 2019 | 水土保持研究2019，26，6： | 15 |
| 2 | Light-triggered interfacial charge transfer and enhanced photodetection in CdSe/ZnS quantum dots/MoS_(2)mixed-dimensional phototransistors显示文摘Mix-dimensional van der Waals heterostructures(vdWHs)have inspired worldwide interests and efforts in the field of ad-vanced electronics and optoelectronics.The fundamental understanding of interfacial charge transfer is of vital import-ance for guiding the design of functional optoelectronic applications.In this work,type-Ⅱ0D-2D CdSe/ZnS quantum dots/MoS_(2)vdWHs are designed to study the light-triggered interfacial charge behaviors and enhanced optoelectronic performances.From spectral measurements in both steady and transient states,the phenomena of suppressed photolu-minescence(PL)emissions,shifted Raman signals and changed PL lifetimes provide strong evidences of efficient charge transfer at the 0D-2D interface.A series of spectral evolutions of heterostructures with various QDs overlapping concentrations at different laser powers are analyzed in details,which clarifies the dynamic competition between exciton and trion during an efficient doping of 3.9×10^(13)cm^(−2).The enhanced photoresponses(1.57×10^(4)A·W^(-1))and detectivities(2.86×10^(11)Jones)in 0D/2D phototransistors further demonstrate that the light-induced charge transfer is still a feasible way to optimize the performance of optoelectronic devices.These results are expected to inspire the basic understand-ing of interfacial physics at 0D/2D interfaces,and shed the light on promoting the development of mixed-dimensional op-toelectronic devices in the near future. | Ziwei Li Wen Yang Ming Huang Xin Yang Chenguang Zhu Chenglin He Lihui Li Yajuan Wang Yunfei Xie Zhuoran Luo Delang Liang Jianhua Huang Xiaoli Zhu Xiujuan Zhuang Dong Li Anlian Pan | 2021 | Opto-Electronic Advances2021，4，9： | 4 |
| 3 | Plasmonically engineered light-matter interactions in Aunanoparticle/MoS_(2) heterostructures for artificial optoelectronic synapse显示文摘Optoelectronic synaptic elements are emerging functional devices for the vigorous development of advanced neuromorphic computing technology in the post-Moore era.However,optoelectronic devices based on transition metal dichalcogenides(TMDs)are limited to their poor mobilities and weak light-matter interactions,which still hardly exhibit superior device performances in the application of artificial synapses.Here,we demonstrate the successful fabrication of Au nanoparticle-coupled MoS_(2)heterostructures via chemical vapor deposition(CVD),where the light absorption of MoS_(2)is greatly enhanced and engineered by plasmonic effects.Hot electrons are excited from Au nanoparticles,and then injected into MoS_(2)semiconductors under the light illumination.The plasmonically-engineered photo-gating effect at the metal-semiconductor junction is demonstrated to create optoelectronic devices with excellent synaptic behaviors,especially in ultra-sensitive excitatory postsynaptic current(EPSC,9.6×10^(-3)nA@3.4 nW·cm^(-2)),ultralow energy consumption(34.7 pJ),long-state retention time(>1,000 s),and tunable synaptic plasticity transitions.The material system of Au-nanoparticles coupled TMDs presents unique advantages for building artificial synapses,which may lead the future development of neuromorphic electronics in optical information sensing and learning. | Zhuoran Luo Yunfei Xie Ziwei Li Yajuan Wang Lihui Li Ziyu Luo Chenguang Zhu Xin Yang Ming Huang Jianhua Huang Delang Liang Xiaoli Zhu Dong Li Anlian Pan | 2022 | Nano Research2022，15，4： | 3 |

| 5 | High-performance optoelectronic devices based on van der Waals vertical MoS2/MoSe2 heterostructures显示文摘Monolayer MoS2 is a direct band gap semiconductor with large exciton binding energy,which is a promising candidate for the application of ultrathin optoelectronic devices.However,the optoelectronic performance of monolayer M0S2 is seriously limited to its growth quality and carrier mobility.In this work,we report the direct vapor growth and the optoelectronic device of verticallystacked MoS2/MoSe2 heterostructure,and further discuss the mechanism of improved device performance.The optical and high-resolution atomic characterizations demonstrate that the heterostructure interface is of high-quality without atomic alloying.Electrical transport measurements indicate that the heterostructure transistor exhibits a high mobility of 28.5 cm^2/(V·s)and a high on/off ratio of 10^7.The optoelectronic characterizations prove that the heterostructure device presents an enhanced photoresponsivity of 36 A/W and a remarkable detectivity of 4.8×10^11 Jones,which benefited from the interface induced built-in electric field and carrier dependent Coulomb screening effect.This work demonstrates that the construction of two-dimensional(2D)semiconductor heterostructures plays a significant role in modifying the optoelectronic device properties of 2D materials. | Fang Li Boyi Xu Wen Yang Zhaoyang Qi Chao Ma Yajuan Wang Xuehong Zhang Zhuoran Luo Delang Liang Dong Li Ziwei Li Anlian Pan | 2020 | Nano Research2020，13，4： | 2 |
