Behaviors of High Explosive near the Critical Conditions for Shock Initiation of Detonation

摘要:

The behaviors of the high explosive near the critical conditions for shock initiation of detonation are investigated by high speed photography and pressure measurements in gap tests. The sample is RDX base explosive, and the inner diameter of donor and acceptor charges is 26 mm. Gap material is PMMA. Near the critical condition, the results under the following conditions have been discussed. 1) Shock to detonation transition (SDT) take place in acceptor, 2) The SDT does not occur, but the reaction wave affects the leading shock front in acceptor, and 3) The gap length in which the effect of the reaction wave to shock front almost disappears. These results are very useful to construct the initiation model for solid explosive.

Characterization of Deep Levels in High-Resistive 6H-SiC by Current Deep Level Transient Spectroscopy

作者: Masashi Kato, Kosuke Kito, Masaya Ichimura

摘要: We measured the temperature dependence of the electrical resistivity for two high-purity undoped 6H-SiC bulk wafers with resistivities of 1.5103 cm and 8.3108 cm at room temperature. We also characterized the deep levels affecting the semi-insulating property by current deep level transient spectroscopy (I-DLTS) and photo induced current level transient spectroscopy (PICTS) measurements. The activation energies of the resistivity were 0.11 eV and 0.59 eV for the samples with lower and higher resistivities, respectively. In I-DLTS and PICTS spectra, the sample with lower resistivity shows a donor level at Ec0.17 eV and two acceptor levels around Ec0.40 eV, while the sample with higher resistivity shows acceptor levels at Ec0.77 eV and Ev+0.46 eV. We calculated the temperature dependence of the resistivity with a model considering one donor level and one acceptor level based on parameters from I-DLTS peaks. We reproduced the experimental results only for the sample with lower resistivity. The acceptor level near the valence band needs to be considered to explain the resistivity for the sample with higher resistivity.

Identification of ZnO Defect Structure by PL Spectroscopy

作者: Peng Fei Cheng, Han Chen Liu, Ying Tang Zhang

摘要: Defect structure of ZnO determines the optoelectronic characteristics of ZnO crystal and film. The identification and modulation of the defect structure is the foundation of the manufacture of optoelectronic devices. Although a good deal of research has been carried out about intrinsic defects and doping defects in ZnO, it is difficult to obtain a conclusive result accepted by all. In the paper, ZnO film is prepared by sol-gel method and the defect structure is expressed by photoluminescent (PL) spectroscopy. Based on some basic rules the intrinsic defect structure of ZnO is confirmed and the interaction of impurity Li and intrinsic defect is discussed. At the same time, some new electronic levels are proposed. It is surprising that although there are fourteen peaks in PL spectra of ZnO film, almost all the peaks can be identified by these basic rules.

Three-Dimensional Two Material Transportation Method Based on the Volume Fractions Interface Algorithm

作者: Ji Lin Wu, Ze Yu Wu, Yu Ping Tong, Pei Rong Du

摘要: In order to solve the problem of three-dimensional two medium transportation problems of fluid dynamics, the transportation principles of a metal ball moving in constant velocity fields were given. The space district was dispersed into some cuboid Euler cells in the directions of three coordinate axes, along which mediums were transported by turns. The continuous boundary condition was adopted to simulate infinite boundary. The interface reconstruction method in the mixture cells was the volume fractions method. The numerical simulation result indicates that the shape and size of the medium cuboid can keep unchanged basically during the medium transportation. The overspeed transportation problem of the volume fractions method in the course of transportation is pointed out. The research may provide certain reference and guidance for solving the multi-material fluid dynamics problems.

Verification of Near-Interface Traps Models by Electrical Measurements on 4H-SiC n-Channel Mosfets

摘要: 4H-SiC n-channel lateral MOSFETs were manufactured and characterized electrically by current-voltage measurements and by numerical simulation. To describe the observed electrical characteristics of the SiC MOSFETs, Near-Interface Traps (NIT) and mobility degradation models were included in the simulation. The main finding of the simulation is that two models for the NIT states in the upper part of the SiC bandgap are able to describe the electrical data equally well. In one of them, acceptor-like traps and fixed charge are considered while in a newly developed one, donor-like traps are taken into account also.
