Dear friends, today is Monday, September 2, 2019, the fourth day of the first month of August in the lunar calendar.
"Taking people as a mirror can make clear gains and losses; taking history as a mirror can know the rise and fall." Looking back at history today, some people should not be forgotten, and some things should not be erased. As the years pass and the clock goes by, they will eventually remain in our memories. "Let's pay attention to what are the selected events of today in history.
Huang Kun profile
Huang Kun was born in Beijing on September 2, 1919, huang kun primary school in Beijing Normal University Affiliated Primary School, Shanghai Guanghua Primary School, middle school in Yanda Affiliated Middle School, Beijing Tongxian Luhe Middle School. He was bright and studious from an early age, with excellent academic performance, and his three years of high school were always the first in the class.
In 1937, Huang Kun was admitted to the Department of Physics of Yenching University. During his university years, he became obsessed with the world's emerging quantum mechanics and completed the paper "The Equivalence of Heisenberg and Schrödinger's Theory of Quantum Mechanics".
In 1956, while serving as a professor in the Department of Physics of Peking University, Huang Kun participated in the establishment of China's first semiconductor physics major and authored the textbook "Solid State Physics".
Major achievements
Huang Kun completed two pioneering academic contributions. One was to propose the famous concepts of the "yellow equation" and the "phonon polarization radical", and the other was the "yellow-reese theory" co-proposed with Reese, who later became his wife. Proposed the theory that impurity defects in solids lead to X-ray diffuse scattering, known as "yellow scattering", and co-proposed a quantum theory of polyphonic radiation and no radiation transitions with Reese; At the same time, Paccar published parallel theories, which were internationally known as the "Yellow-Pecar Theory" or "Yellow-Rees Theory"; The coupled oscillation mode of phonons and electromagnetic waves in crystals was proposed, and the equations proposed at that time were called the "Yellow Equation"; Study of semiconductor quantum well superlattice physics. The theory of superlattice optical vibration was established, and the theory was published that was later called the "Yellow-Zhu Model" by the international physics community.
Huang Kun analyzed in detail the electronic states of the quantum wells and the hole bands of the superlattices of the III.-V. compounds, and developed a simple and effective calculation method suitable for the superlattice structure, so as to make theoretical calculations on the properties of the hole substrips in the quantum wells and superlattices structures, valence band hybridization and applied electric fields on the absorption of excitons in the quantum wells and superlattices. He and his students systematically studied long-wave optical vibration patterns in the superlattice, and they proposed a theoretical model that could describe the experimental facts learned so far, and obtained a correct description of the body-like modes of longitudinal optical vibration and transverse optical vibration in one- and two-dimensional quantum systems. Their work has played an important role in understanding the optical properties of semiconductor superlattices, the effect of light scattering, and the interaction of electrons and lattice waves.
Character evaluation
Mr. Huang Kun's most important contribution is to establish the five schools to unite semiconductor specialization, cultivate a group of outstanding talents for the country's semiconductor science and technology undertakings, and play a pioneering role in creating and developing China's semiconductor science and technology and education, and establishing and developing the semiconductor industry system from scratch. The advanced educational ideas advocated by him, such as self-reliance, unity and cooperation, and multi-party struggle for educational resources, are always worth learning and carrying forward.
Posthumous Commemoration:
On December 15, 2006, the inauguration ceremony of Mr. Huang Kun's bronze statue, jointly sponsored by the School of Physics of Peking University, the Institute of Microelectronics of Peking University, and the State Key Laboratory of Artificial Microstructure and Mesoscopic Physics, was held in the Physics Building of Peking University, and the relevant leaders and his relatives unveiled the bronze statue together.
