Problems solved by technology

It can be seen that the characteristics and process of growing one-dimensional nanostructures by traditional CVD methods have certain limitations and shortcomings: 1. Different types of nanostructures have strong selectivity to catalysts; 2. The size of nanostructures depends on the catalyst Particle size; 3. Special catalyst coating and growth equipment are required, and the cost is high; 4. It is difficult to grow ternary or more nanowires; 5. The existence of catalyst particles has a significant impact on the performance of nanostructure arrays. Limited; 6. Large-area preparation is limited by the size of coating equipment and growth equipment, the cost increases sharply, and the growth process is complicated
