摘要:In contrast to the strength of single crystals, stacking faults (SFs) are usually an unfavorable factor that weakens materials. Using molecular-dynamics simulations, we find that parallel-spaced SFs can dramatically enhance the strength of zinc-blende SiC nanorods, which is even ...

摘要:In this paper, a DC-coupling readout circuit is presented in order to readout the signal from CdZnTe detectors. A differential stage is added in CSA to compensate the leakage current introduced by the CdZnTe crystal. A compact shaper is designed to achieve low area with wide...

摘要:We study the performance of a large-area 2-D Multigap Resistive Plate Chamber (MRPC) designed for muon tomography with high spatial resolution. An efficiency up to 98% and a spatial resolution of around 270 μ m are obtained in cosmic ray and X-ray tests. The performance of the...

摘要:Bright Stars Survey Telescope (BSST) is a photometry telescope prepared to be installed in the Kunlun station, Antarctica. In this paper, a scientific Charge-coupled Device (CCD) camera with 4K × 4K pixels designed for the BSST running in the extremely low temperature enviro...

摘要:The shot noise in a toroidal carbon nanotube (TCN) interferometer under the perturbation of a rotating magnetic field (RMF) has been investigated. A general shot noise formula has been derived by calculating the current correlation. It was found that photon absorption and emissio...

摘要:CMOS Active pixel sensors (CMOS APS) are attractive for use in the innermost layers of charged particle trackers, due to their good tradeoffs among the key performances. However, CMOS APS can be greatly influenced by random telegraph signal (RTS) noise, which can cause particle t...

摘要:Ion internal transport barriers (iITBs) are first observed in neutral beam injection (NBI) heated plasmas at the HL-2A tokamak. The position of the barrier foot, in the stationary state, coincides with the q = 1 surface within its uncertainty of measurement. iITBs can develo...

摘要:The diesel spray characteristics are strongly influenced by the flow dynamics inside the injector nozzle. Moreover, the off-axis oscillation of needle could lead to variation of orifice flow in the nozzle. In this paper, the needle oscillation was investigated using high-speed X-...

摘要:We theoretically investigate the quantum Hall effect in a graphene superlattice (GS) system, in which the two valleys of graphene are coupled together. In the presence of a perpendicular magnetic field, an ordinary quantum Hall effect is found with the sequence . At the zeroth Ha...

摘要:In this paper, we present a dual-channel serializer ASIC, LOCx2, and its pin-compatible backup, LOCx2-130, for detector front-end readout. LOCx2 is fabricated in a 0.25-μm Silicon-on-Sapphire CMOS process and each channel operates at 5.12 Gbps, while LOCx2-130 is fabricated in...
