More than 80 years of theories and experiments on water suggested to us, described in our first water-physics report, that pure water's "abnormally" high electrical conductivity is due to transport of positive and negative quasi-protons, p+ and p-, between the neutral proton traps V (H20) in the extended water, [(H20)N]+, converting it respectively to positively and negatively charged proton traps, V+ = (H30)1+ and V- = (HO)1-. In this second report, we present the theoretical charge control capacitances of pure and impure water as a function of the DC electric potential applied to water.  相似文献

On the basis of analysing traditional motor ignitor, a new motor ignitor design with precise ignition angle control, consistency and low cost is proposed. Techniques of low pertinence to process and power supply are introduced to promote its stability, reliability and unity. This circuit is implemented with a standard CMOS technology with perfect electric static discharge(ESD) design and can work under a broad range of power supply from 3 V-5 V with a quiescent current less than 2 mA and can be widely used in motor with a displacement of 125 ml and below.  相似文献

A novel silicon light emitting device was realized with standard 0.35μm 2P4M Mixed Mode/RF CMOS technology. The device functions in a reverse breakdown mode and can be turned on at 8.3 V and operated normally at a wide voltage range of 8.3 V-12.0 V. An output optical power of 13.6 nW was measured at the bias of 10 V and 100 mA, and the emitted light intensity was calculated to be more than 1 mW/cm2. The optical spectrum of the device is in the range of 500-820 nm.  相似文献

A conduction channel model is propsed to explain the high conductivity property of nc-Si:H.Detailed energy band diagram is developed based on the analysis and calculation ,and the conductivity of the nc-Si:H was then analysed on the basis of energy band theory.It is assumed that the conductivity of the nc-Si:H stems from two parts:the conductance of the interface,where the transport mechanism is identified as a thermal -assisted tunneling process,and the conductance along the channel around the grain,which mainly determined the high conductivity of the nc-Si:H.The conductivity of nc-Si:H is calculated and compared with the experiment data .The theory is in agreement with the experiment.  相似文献

Static and dynamic properties of both complementary n-Ge/p-Si and p-Ge/n-Si hetero-junction Double-Drift IMPATT diodes have been investigated by an advanced and realistic computer simulation technique,developed by the authors,for operation in the Ka-,V- and W-band frequencies.The results are further compared with corresponding Si and Ge homo-junction devices.The study shows high values of device efficiency,such as 23%, 22%and 21.5%,for n-Ge/p-Si IMPATTs at the Ka,V and W bands,respectively.The peak device negative conductances for n-Si/p-Ge and n-Ge/p-Si hetero-junction devices found to be 50.7×10~6 S/m~2 and 71.3×10~6 S/m~2, which are~3-4 times better than their Si and Ge counterparts at the V-band.The computed values of RF power-density for n-Ge/p-Si hetero-junction IMPATTs are 1.0×10~9,1.1×10~9 and 1.4×10~9 W/m~2,respectively,for Ka-,V- and W-band operation,which can be observed to be the highest when compared with Si,Ge and n-Si/p-Ge devices.Both of the hetero-junctions,especially the n-Ge/p-Si hetero-junction diode,can thus become a superior RF-power generator over a wide range of frequencies.The present study will help the device engineers to choose a suitable material pair for the development of high-power MM-wave IMPATT for applications in the civil and defense-related arena.  相似文献

Composites consisting of hydrogenated amorphous silicon (a-Si: H, inorganic) and zinc phthalocyanine (ZnPc, organic) were prepared by vacuum evaporation of ZnPc and sequential deposition amorphous silicon via plasma enhanced chemical vapor deposition (PECVD). The optical and electrical properties of the composite film have been investigated. The results demonstrate that ZnPc can endure the temperature and bombardment of the PECVD plasma and photoconductivity of the composite film was improved by 89.9% compared to pure a-Si: H film. Electron mobility-lifetime products/lr of the composite film were increased by nearly one order of magnitude from 6.96 × 10^-7 to 5.08 × 10^-6 cm2/V. Combined with photoconductivity spectra of the composites and pure a-Si: H, we tentatively elucidate the improvement in photoconductivity of the composite film.  相似文献

An analysis is given to explain the instability of the high conductivity property of nc-Si:H fabricated.Detailed discussion is carried out concentrating on the conductivity and growth mechanism.It is assumed that the instability of the conductivity of the nc-Si:H stems from two part:the phase transition from nanocrystallites into a -Si:H,and the oxygen incorporation of the thin layer of the film,which contributes more to the effect when the film suffers the exposure to air.The theory is in agreement with the experiment and measurement.  相似文献
