The materials for stab-resistance can be categorized as soft type, hard type and compound type.
Compound type is composed of multi-layers made of high-performance fiber majorly, and supplemented by metal and ceramic materials.
In the meantime, fiber materials have good flexibility and are easy for people to wear and move, but its stab-resistance was not as good as that of metal materials or ceramics [2].
Meanwhile, low melting polyester fibers had a thickness of 6 denier , a length of 51mm, and a melting point of 110℃ for its outer layer ; moreover, its core materials were normal polyester materials with a melting point as 265℃.

Introduction Nitride semiconductor materials are widely used in display, data storage, high frequency and high-power devices, ultraviolet photodetectors, and other related devices due to their excellent characteristics.
The poor quality and lack large size of gallium nitride (GaN) single crystal substrate materials has made technologies widely using sapphire and SiC as substrate for hetero-epitaxial GaN materials.
Silicon (Si) substrate has some excellent characteristics: cheap, good heat and electrical conductivity, low hardness, made out of large high-quality single crystal materials, and easy to process due to a mature processing device technology.
Furthermore, Si used as substrates may achieve optoelectronic integration of silica-based material, causing Si to become one of the most attractive substrate materials for GaN epitaxy [1-3].
Interference microscope (Olympus BX51) and AFM (Chinese Academy of Sciences Chemistry Division CSPM3100) were used to analyze the macro- and micro-surface appearance.
