The I-V characteristics of the diodes with 100μm diameter indicated that as the densities of V-defects on GaN films increased from 4.1×105cm-2 to 1.03×107cm-2, the Schottky barrier height decreased from 1.44eV to 1.19eV and the reverse bias leakage current at -1V is increased sharply from 10-10A to 10-7A . Further studies on a single V-defect using conductive atomic force microscope demonstrated that the value of forward current biased at 8V at V-defect side-walls appears to be one order higher than that of plain region, indicating that the conductivity mainly occurred at the side-walls of V-defect.

A prediction model has been proposed to deal with threshold voltage shift as a function of 1MeV neutron flux and gate oxide thickness, and to deal with room-temperature annealing of threshold voltage shift induced-by 〓Coγ as a function of electric field and gate oxide thickness. The commonness and individuality of MOS device degradation between hot-carrier effect and ionizing radiation were investigated. The dependence of substrate current, gate current and threshold voltage shift due to hot-carrier on gate oxide thickness were simulated with MEDICI-2D simulator. The photocurrents of PN junction and bipolar transistor were studied. Their transient responses on varied bias voltages, pulse durations and absorbed doses were simulated. The influences of NPN base width on base and collector photocurrents were investigated. We also studied 1MeV neutron displacement damage in PN junction, and calculated reverse current leakage under the neutron flux of 2. 67×10〓 per square centimeter. 3 The study of nondestructive screening method for MOS radiation tolerance A theoretical and experimental study of nondestructive screening methods for radiation tolerance of nMOS and pMOS were firstly fulfilled. We determined the informative parameters pertinent to the method and proposed how to deal with experimental data and verify obtained results statistically, as well as make the required steps for nondestructive screening. Based on the experimental data of 180 samples of discrete pMOS devices, the relation between sample quantity and correlation coefficient, screening equation, and other significant results were obtained from the threshold voltage shifts of pre-and post-irradiation samples.

After take analyzed deeply for the opened magnet circuit with FEMM (Finite Element Method Magnetics) we find out the field distributing that is separated into three sections . One is the main area what we called as positive field section. Beside the main field there are tow areas that are called the inverted field sections. Loudspeaker arise a very serious distortion when the voice coil moving into inverted field areas. The direction of induced current in the coil part of entered inverted field area is same with the current driving into loudspeaker so that total currents increas largely and heat increase rapidly. With more coils moving into inverted area the voice coil will take on negative inductance properties. It is the main reason that voice coil is burned by heating with increasing current due to arise negative inductance. So opened magnetic circuit is not suitable for the woofers in which the voice coil have wider displacement range. When using this kind magnetic circuit design, the voice coil moving range should be less than the range of positive field to avoid loudspeaker arise serious distortion and heating. Even though voice coil moving range is in the positive area, loudspeaker will still arise more distortion because the field distribution is very cliffy at tow sides of the positive area and full range of magnetic field distribution is not parallel that will arise distortion. Base on above reasons, opened magnetic circuit is not an ideal magnetic circuit for low-frequency loudspeakers. But it can be used in mid-range or high-frequency productions.

开式磁路是由2片钕铁硼磁铁和主导磁板和导磁垫片组成,我们在实践过程中发现这种磁路结构不适合于低频扬声器的使用,我们通过使用FEMM(Finite Element Method Magnetics)软件包对该磁路进行了分析,该磁路的磁场范围被分成3个区域,其中在主导磁板附近形成一个正向磁场,在正向磁场的两边存在反向的磁场,音圈在工作时有很大一部分进入了反向磁场中,在反向磁场内线圈的感应电流方向与驱动电流方向相同,使得音圈呈现出负感抗特性,由于音圈的负感抗特性引起电流的增加导致音圈发热甚至烧毁,因此在扬声器中使用开式磁路时,音圈的运动范围应控制在正向磁场范围之内,否则音圈运动到反向磁场区域时将会产生很大的失真和发热,即使在设计时已经将音圈的运动范围控制在正向磁场范围之内,由于正向磁场的2个边缘磁场强度衰减太快,同时开式磁路中磁场的分布不是平行的,而是自由发散的分布,这样肯定会导致扬声器的非线性失真,因此我们得到的结论是:开式磁路并不是一个理想的磁路,它不适合于低频扬声器的使用,但它还可以应用于中高频扬声器。

Since Al〓Ga〓In〓P possesses larger valence band difference to GaAs and wider energy gap, minor carrier reverse injection from base and space charge region recombination in the emitter are effectively suppressed in Al〓Ga〓 In〓P/GaAs HBT. Under most circumstances, quasi-neutral base recombination current dominates the base current, and its ratio to collector current varies little with collector current and temperature, thus greatly stabilizes the current gain.

Al〓Ga〓〓In〓P/GaAs HBT由于异质结的△Ev较大,发射区禁带较宽,有力地抑制了基区少子反向注入流和发射区空间电荷区复合电流;在大多数情况下,基极电流以准中性基区复合电流为主,其与集电极电流的比值随集电极电流和温度的变化极小,稳定了电流增益。
