The spatial distribution of chemical elements is studied in high-κ, metal-gated stacks applied field effect transistors. Using the transmission electron microscope (TEM)-based analytical techniques energy-loss spectroscopy (EELS) and energy-dispersive x-ray spectroscopy, it demonstrated that Al2O3 La2O3 capping layers show distinctly different diffusion profiles. importance EELS collection angle discussed. Popular models assume La-rich interface are rejected.
A wafer-level 3D monolithic integration of the scandium aluminum nitride (ScAlN) based radio frequency (RF) bulk acoustic wave (BAW) filters with RF silicon-on-insulator (RFSOI) switches were demonstrated for first time, aiming significant reduction footprint and parasitics next generation frontend modules in wireless communication systems. The integrated switched filter operating at 2.5GHz achieves an insertions loss <3.6 dB bandwidth >120 MHz within a compact area <1mm <sup...
This paper describes the design and construction of automatic calibration unit (ACU) for JUNO experiment. The ACU is a fully automated mechanical system. It capable deploying multiple radioactive sources, an ultraviolet (UV) laser source, or auxiliary sensor such as temperature sensor, one at time, into central detector along axis. designed primary tool to precisely calibrate energy scale detector, aligning timing photosensors, partially monitoring position-dependent variations.
During the operation of power grid, cables may be damaged by harmful factors such as aging, corrosion, and external forces, leading to cable breakage. Cable breakage can cause adverse consequences outages personal injury. The existing joint connection methods have more or less defects being unsuitable for frequent disassembly assembly, high installation technology requirements, inability used a long time, connect multiple simultaneously, maintenance costs. Therefore, they not been widely...
