From the self-consistent solution of 2-D Poisson equation and Schrdinger equation,the electron states and pinch-off behavior in quantum well channel of GaN HFET under longitudinal and transversal electric field were investigated.

Deformation and fracture characteristics of ferrite/bainite dual-phase steels

Studies of fracture characteristics of high strength plastic pipes abroad are analyzed in detail.

The effects of different structural parameters on the fracture characteristics were analyzed.

Study on fracture behaviors of induced joints in RCC arch dams;

Dynamic in situ observation for the fracture process of the materials has been put forward fracture mould of SiC/7075A1 composite materials have been established with the purpose of disclosure of the fracture behavior of SiC/7075A1 composite materials.

The fracture behaviorof granular structure and granular bainite by low tempering and high tempering in 17Cr2Ni2Mo steel were studied.

But the circuit stray inductance has serious influence upon the turn-off characteristic of IGCTs.

The turn-off characteristics determining the maximum operating frequency of ultra-fast photoconductive semiconductor switches are influenced by many factors.

Purpose of the work is to propose a new device structure which suppresses parasitic latch-up effectively and also improves a turn-off characteristic by cascading of lateral high voltage devices LDMOS and LIGBT together without any considerable sacrifices of forward characteristic.
