作者： 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 Centre de nanosciences et de nanotechnologies CNRS University of Paris-Sud Université Paris-Saclay University Grenoble Alpes and CEA LETI Minatec Campus Technology R&D STMicroelectronics SAS

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.

塔西南玄武岩年代学和地球化学特征及其对二叠纪地幔柱岩浆演化的制约

本文通过对塔西南达木斯剖面中玄武岩进行 K-Ar 同位素定年,获得年龄为289.6Ma,并结合 Ar-Ar 坪年龄结果(290.1Ma)和古生物以及沉积特征,认为290Ma 的年龄代表了塔西南玄武岩形成于早二叠世,对应于盆地内下二叠统库普库兹满组下段层位的年龄。地球化学特征显示塔西南熔岩为分异的碱性玄武岩并含45%SiO_2和4%MgO 含量。塔西南玄武岩与盆地内柯坪玄武岩具有相近的主量元素含量和稀土配分与微量元素蜘蛛网图型、无 Eu 异常、富集轻稀土元素、较高的其它不相容元素(如高场强元素)。但塔西南玄武岩比柯坪玄武岩具有较高的 Al_2O_3和 CaO 含量及稀土总量(288×10^(-6)～358×10^(-6)),偏低的 na,O,P_2O_5和 FeO 含量。K、Rb 和 Cs 丰度的无系统性变化主要受这些元素丰度本身变化的影响。对其它不活动组分,塔西南玄武岩具有高 Ti(Ti/Y=522～624)和 Nb 含量(30×10^(-6)～40×10^(-6))及低 Zr/Nb 比值,暗示其来自富集的地幔源区。其 Nb 含量相对 La 含量无显著变化以及相对低的 Nb/U(近30)和 Ce/Pb 比值(近15),指示塔西南玄武熔岩来自大陆岩石圈或受一定程度的地壳混染。塔里木盆地大规模的火山喷发以及富集不相容元素的地球化学特征支持这样一种假设,即塔西南玄武岩来自地幔柱火山作用,或由于地幔柱的供热和上升导致富集的岩石圈地幔部分熔融而形成。且岩浆作用过程以部分熔融为主,结晶分异作用较弱。基于塔西南玄武岩和柯坪玄武岩相近的时代、源区成分和/或岩浆作用过程以及处于陆内稳定构造环境,笔者认为塔里木二叠纪玄武岩的分布范围可以从塔里木盆地内的塔中、柯坪一带一直延伸到塔西南地区。

This paper aims at comparing the lexical prepositions of the Ibibio and Igbo *** objectives are to identify what constitute lexical prepositions in Ibibio and Igbo and highlight the similarities and differences between Ibibio and Igbo lexical *** Ibibio data used for analysis were elicited from two Ibibio native speakers whereas Igbo data were obtained through *** Ibibio and Igbo data were analysed *** findings of the research reveal that the lexical prepositions obtainable in Ibibio are ke‘to,in,for,at’,mme‘with’,ano‘from’,and ito/nto‘from’.In Igbo,some of the lexical prepositions include:na‘to,in,at,from’,maka‘for’,and gbasara‘about’.The similarity observed between Ibibio and Igbo lexical prepositions is that they both occur before a Noun Phrase(NP),that is,they take NP as their *** terms of their differences,the preposition‘to’is marked in Igbo but is unmarked in *** preposition‘with’is overtly marked in Ibibio with mme but it is implied in Igbo *** notable difference between Ibibio and Igbo lexical prepositions is that the English preposition‘from’inflects for number in Ibibio but such feature is absent in *** paper recommends that further comparative researches should be carried out on other types of preposition like the category incorporated prepositions,and other word classes between Ibibio and Igbo in particular and other African languages in general.

王成源 (Wang,2 0 0 0 )和金玉 (Jin,2 0 0 0 )提出了关于乐平统底界定义的不同论点。为了对此进行独立的验证 ,卡尔加里大学微体古生物实验室对采自华南广西来宾地区瓜达鲁普统 -乐平统界线地层的牙形类化石大块样品进行了处理。结果如下 :***和 Clarkina在样品中没有共生 ;2 .由 Jinogondolella granti演化为Clarkina postbitteri 的变化发生在层 115 - 6 i;*** 的首次出现层位 (FAD)在蓬莱滩剖面位于层 115 - 6 i上部 ;4.这个变化标志着一个显著的生物信号和一个重要的点断演化事件。Jinogondolella granti演化为 Clarkinapostbitteri的事件很可能是受瓜达鲁普统与乐平统之交的海平面降至最低水位所触发和控制。层 115 - 6 i下部为较浅水相颗粒灰岩 ,代表瓜达鲁普统末期层序高位域之顶或上覆层序低位域之底部。作为 Clarkina属的第一个代表 ,Clarkina postbitteri是界线地层中最易识别的种之一 ,而 Clarkina postbitteri带的识别较容易和稳定一致。Clarkinapostbitteri和 Clarkina dukouensis可以通过基于锯齿型式 ,居群和个体发育的分类体系来加以稳定地区分。Clarki-na p ostbitteri和 Clarkina dukouensis之间的过渡是渐变的 ,其间的分界点只能人为地确定。
