To study internal force and deformation of concrete frame structure whose plane is arc under temperature variations, it is compared with rectangular and ring-shaped concrete frame structure. Its characteristics are summarized. Results indicate that mechanical behavior of arc-shaped concrete frame structure under temperature variations depends on the position of fixed point- center of rigidity. Radial...
Based on the material characteristics and the carrier recombination theory, the common emitter current gain of the double base epilayer BJTs is modeled and calculated when considering four recombination processes. The results show that the SiC/SiO2 interface states and the quality of the passivation layer will affect the surface recombination velocity, and make an obvious current gain fall-off at...
4H-SiC Junction Barrier Schottky diode with embedded P-layer (JBS-EPL) is reported in this paper. JBS-EPL has attractive advantages, such as remarkably increasing the breakdown voltage and decreasing the power loss and die area comparing with conventional Junction Barrier Schottky diode. The estimates for power loss and die area are proposed that can be used for evaluating the different structure...
