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). Please follow Light People and discover what challenges Prof. Chu had to overcome in the study of mercury cadmium telluride.
