【摘要】

：

运行于欧洲核子研究中心(CERN)的大型强子对撞机(LHC)是当今世界上最大的粒子物理实验设施.自2009年正式运行取数以来,已为粒子物理研究积累了海量实验数据,并于2012年发现了希格斯粒子(Higgs),成功证明了希格斯机制赋予基本粒子质量的正确性.rn中国合作组参与了LHC上所有的大型实验,并承担了众多粒子探测器的建造与升级工作,其中就包括阻性板室气体探测器(Resistive Plate Chamber,下文简称RPC).RPC作为一类工艺简单、结构多样、造价低廉的粒子探测器,除了在LHC的各子实

Synthesis and thermoelectric properties of Bi-doped SnSe thin films

Bi doped n-type SnSe thin films were prepared by chemical vapor deposition (CVD) and their structure and thermo-electric properties were studied.The x-ray diffraction patterns,x-ray photoelectron spectroscopy,and microscopic images show that the prepared

Intrinsic two-dimensional multiferroicity in CrNCl2 monolayer

Two-dimensional multiferroics,which simultaneously possess ferroelectricity and magnetism in a single phase,are well-known to possess great potential applications in nanoscale memories and spintronics.On the basis of first-principles calculations,a CrNCl2

Photoemission oscillation in epitaxially grown van der Waals β-In2Se3/WS2 heterobilayer bubbles

Thin films of millimeter-scale continuous monolayer WS2 have been grown on SiO2/Si substrate,followed by the de-position of β-In2Se3 crystals on monolayer WS2 to prepare In2Se3/WS2 van de Waals heterostructures by a two-step chem-ical vapor deposition (CV

Pure spin-current diode based on interacting quantum dot tunneling junction

A magnetic field-controlled spin-current diode is theoretically proposed,which consists of a junction with an inter-acting quantum dot sandwiched between a pair of nonmagnetic electrodes.By applying a spin bias Vs across the junction,a pure spin current c

On the structural and optical properties investigation of annealed Zn nanorods in the oxygen flux

Zn nano rods were produced on glass substrates using oblique angle deposition method at different deposition angles.For oxidation,the samples were placed in a furnace under oxygen flux.AFM and FESEM images were used to morphology analysis of the structure

Steady and transient behavior of perylene under high pressure

Pressure can reduce the distances among atoms,thereby modifying the overall optical characteristics of molecules.In this article,the excited state behavior of perylene is carefully observed under isotropic pressure and non-complexing condition.In a steady

Degradation and its fast recovery in a-IGZO thin-film transistors under negative gate bias stress

A new type of degradation phenomena featured with increased subthreshold swing and threshold voltage after negative gate bias stress (NBS) is observed for amorphous InGaZnO (a-IGZO) thin-film transistors (TFTs),which can recover in a short time.After comp
