Light People: Academician Junhao Chu
No full textEditorial The industrial revolutions of steam power, electric power and digital power have been three key steps in the development of science and technology. Now, the fourth industrial revolution has quietly begun, a revolution which will combine the powers of modern technologies such as the Internet, industrial digitalization and virtual reality to trigger a major change of science and technology, and sensor technology is of vital importance to this process. A famous physicist specialized in infrared and semiconductors, our featured guest not only discovered the intrinsic absorption spectra of the optical transition between narrow gap semiconductor mercury cadmium telluride bands, but also developed the theory of the band structure of mercury cadmium telluride and the theory of optical transition, put forward a series of expressions such as the gap width of mercury cadmium telluride bands, making outstanding contributions. Born into a scholarly family, he inherited a love for knowledge, especially physics and enjoyed all the challenges it presented. In research, he believes that technological development should be guided by the laws of physics. As a teacher, he asks his students to focus on the depth and breadth of learning. In life, he is famed for being easygoing, modest, well-mannered and meticulous. He is Academician Junhao Chu of the Shanghai Institute of Technical Physics (SITP), Chinese Academy of Sciences (CAS).
