Cultivate students in schools. Ph.D. in physics is extremely rich in gold, teaching and educating people in schools, and training a large number of talents for the country. Graduates have been widely recognized by the society. The students brought out by doctors of physics have strong learning ability and high professionalism, especially in scientific research and innovation. After graduation, it was widely welcomed by scientific research institutions, universities, enterprises and institutions, and doctors in physics trained students in schools. A doctor majoring in physics can become an expert in many engineering fields if he has a solid theoretical foundation and application experience in physics. China trains about 12000 undergraduate doctoral talents in applied physics every year, and the majors that cross this major include physics, engineering physics, semiconductors, materials and so on. In terms of talent demand, the demand for applied physics professionals in China is still in short supply. Many physics research topics are still basic and often require a lot of government policy investment, so it is difficult to realize industrialization. For doctors who intend to engage in applied physics research after graduation, they should be psychologically prepared. But in recent years, with the rapid development of science, cutting-edge technologies developed by many physics industries have been rapidly applied.
