| 1 | Empirical estimates of regional carbon budgets imply reduced global soil heterotrophic respiration显示文摘Resolving regional carbon budgets is critical for informing land-based mitigation policy.For nine regions covering nearly the whole globe,we collected inventory estimates of carbon-stock changes complemented by satellite estimates of biomass changes where inventory data are missing.The net land–atmospheric carbon exchange(NEE)was calculated by taking the sum of the carbon-stock change and lateral carbon fluxes from crop and wood trade,and riverine-carbon export to the ocean.Summing up NEE from all regions,we obtained a global‘bottom-up'NEE for net land anthropogenic CO_(2)uptake of–2.2±0.6 Pg C yr^(-1)consistent with the independent top-down NEE from the global atmospheric carbon budget during 2000–2009.This estimate is so far the most comprehensive global bottom-up carbon budget accounting,which set up an important milestone for global carbon-cycle studies.By decomposing NEE into component fluxes,we found that global soil heterotrophic respiration amounts to a source of CO_(2)of 39 Pg C yr^(-1)with an interquartile of 33–46 Pg C yr^(-1)—a much smaller portion of net primary productivity than previously reported. | Philippe Ciais Yitong Yao Thomas Gasser Alessandro Baccini Yilong Wang Ronny Lauerwald Shushi Peng Ana Bastos Wei Li Peter A.Raymond Josep G.Canadell Glen P.Peters Rob J.Andres Jinfeng Chang Chao Yue A.Johannes Dolman Vanessa Haverd Jens Hartmann Goulven Laruelle Alexandra G.Konings Anthony W.King Yi Liu Sebastiaan Luyssaert Fabienne Maignan Prabir K.Patra Anna Peregon Pierre Regnier Julia Pongratz Benjamin Poulter Anatoly Shvidenko Riccardo Valentini Rong Wang Grégoire Broquet Yi Yin Jakob Zscheischler Bertrand Guenet Daniel SGoll Ashley-P.Ballantyne Hui Yang Chunjing Qiu Dan Zhu | 2021 | National Science Review2021，8，2： | 3 |
| 2 | High-performance waveguide-integrated germanium PIN photodiodes for optical communication applications[Invited]显示文摘This paper reports on high-performance waveguide-integrated germanium photodiodes for optical communications applications.200 mm wafers and production tools were used to fabricate the devices.Yields over 97%were obtained for three different compact photodiodes(10×10μm and intrinsic region width of 0.5,0.7,and 1μm)within the same batch of three wafers.Those photodiodes exhibit low dark currents under reverse bias with median values of 74,62,and 61 nA for intrinsic widths of 0.5,0.7,and 1μm,respectively,over a full wafer.Responsivities up to 0.78 A∕W at 1550 nm and zero bias were measured.Zero bias operation is possible for 25 and 40 Gbps with receiver sensitivity estimated to−13.9 and−12.3 dBm,respectively. | Léopold Virot Laurent Vivien Jean-Marc Fédéli Yann Bogumilowicz Jean-Michel Hartmann Frédéric Bœuf Paul Crozat Delphine Marris-Morini Eric Cassan | 2013 | Photonics Research2013，1，3： | 2 |
| 3 | 25 Gbps low-voltage hetero-structured silicongermanium waveguide pin photodetectors for monolithic on-chip nanophotonic architectures显示文摘Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits. | DANIEL BENEDIKOVIC LéOPOLD VIROT GUY AUBIN FARAH AMAR BERTRAND SZELAG BAYRAM KARAKUS JEAN-MICHEL HARTMANN CARLOS ALONSO-RAMOS XAVIER LE ROUX PAUL CROZAT ERIC CASSAN DELPHINE MARRIS-MORINI CHARLES BAUDOT FRéDéRIC BOEUF JEAN-MARC FéDéLI CHRISTOPHE KOPP LAURENT VIVIEN | 2019 | Photonics Research2019，7，4： | 2 |

| 12 | Spatio-temporal changes of exposure and vulnerability to floods in China显示文摘A socio-economic data set on China's historical flood losses for the period 1984e2012 was compiled to analyze the exposed population,economy,and crop area as well as the vulnerabilities of the population and economy to floods.The results revealed that the exposed population was approximately 126 persons km 2per year when taking China as a whole;in terms of the economy,potential losses due to floods were estimated to be approximately 1.49 million CN$km 2and the crop area exposed to floods covered 153 million hm2per year.China's total exposure to floods significantly increased over the analysis period.The areas that showed the higher exposure were mainly located along the east coast.The population's vulnerability to floods showed a significantly increasing trend,however,the economic vulnerability showed a decreasing trend.The populations and economies that were most vulnerable to floods were in Hunan,Anhui,Chongqing,Jiangxi,and Hubei provinces.The municipalities of Shanghai,Beijing,and Tianjin showed the lowest vulnerabilities to floods. | WANG Yan-Jun GAO Chao ZHAI Jian-Qing LI Xiu-Cang SU Bu-da HARTMANN Heike | 2014 | Advances in Climate Change Research2014，5，4： | 1 |
