Water hydraulic technology has been developing rapidly over the past decades due to its outstanding advantages, including cleanliness, security, environmental protection and cost-effectiveness and so on. At present, the research and development of water hydraulic servo valve with the performance of high precision, frequency response and high reliability become an important direction of water hydraulic...
In this paper, we analyze LDD depletion effects in fully-depleted SOI (FDSOI) devices with thin-BOX and ground plane (GP). LDD engineering is introduced to reduce the source and drain resistance and threshold voltage shifts. Short-channel effects are rather insensitive to SOI layer thickness variations and remains well controlled for gate lengths down to 15 nm.
The heat transfer distribution in U-shaped variable cross-section channels with bleeding holes was experimentally studied in the state of static. The ribs are configured in an in-line arrangement with an attack of 90 deg to the main flow. The relative roughness pitch is 25 mm, the rib width and height is 2 mm respectively. The Renault number varies from 12000 to 46000. Analysis of the experimental...
A two-step method was used to fabricate vanadium oxide (VOX) thin films. SEM and IR transmittance spectra were employed to reveal the cross-section morphology and optical property, respectively. The surface composition was obtained using XPS. Experimental results indicated that the VOX film was stable until the grains and insulator-metal transition showed up on increasing annealing pressure or prolonging...
A double-sided wave absorber with specified reflection and transmission coefficients at both sides is proposed. This wave absorber consists of two transparent dielectric layers with three transparent resistance films. Therefore, this wave absorber is transparent and electromagnetic waves are absorbed in both sides. Then it is suitable for the indoor use as electromagnetic wave separator. The design...
Summary form only given. Single-walled carbon nanotube (CNT) films are a new class of transparent, conductive, and flexible materials, and they exhibit uniform physical and electronic properties. Several promising device applications of CNT films have recently been demonstrated, such as thin film transistors, optoelectronic devices, and chemical sensors. For many of these applications, intrinsic noise...
In this paper, the bipolar resistive switching memory using HfO2 film with a TiN/Ti bi-layer electrode is reported. A robust endurance (>106 cycles) and long data retention (>10 years at 200degC) of this memory device was achieved. The memory also shows fast operation speed (~10 ns), low operation power and capability of multi-level operation.
We present the use of swept wavelength interferometry for distributed fiber-optic temperature measurements in a nuclear reactor. The sensors consisted of 2-m segments of commercially available, single mode optical fibers. The interrogation technique is based on measuring the spectral shift of the intrinsic Rayleigh backscatter signal along the optical fiber and converting the spectral shift to temperature.
