Dear friends, today is September 2, 2019, Monday, the fourth day of August in the Lunar New Year.
"With people as a mirror, you can understand gains and losses; with history as a mirror, you can know the rise and fall. Looking back at today in history, some people should not be forgotten, and some things should not be obliterated. Time changes, time passes, they will eventually Stay in our memory." Come to and pay attention to the selected events in history today.
Introduction to Huang Kun
On September 2, 1919, Huang Kun was born in Beijing. Huang Kun primary school studied at the Primary School Affiliated to Beijing Normal University and Shanghai Guanghua Primary School. He spent his middle school at the High School Attached to Yan University and Luhe Middle School in Tongxian County, Beijing. He has been smart and eager to learn since he was young, with excellent academic performance, and his three-year high school performance has always been the first in the class.
In 1937, Huang Kun was admitted to the Department of Physics of Yenching University. While in university, he was obsessed with the world's emerging quantum mechanics and completed the thesis "The Equivalence of Heisenberg and Schrodinger Quantum Mechanics Theory".
In 1956, when Huang Kun was a professor in the Department of Physics at Peking University, he participated in the creation of China's first major in semiconductor physics and authored the textbook "Solid State Physics".
main achievements
Huang Kun completed two pioneering academic contributions. One is to put forward the famous concepts of "Huang equation" and "phonon polarization excimer", and the other is to put forward the "Huang-Ries theory" jointly with Ries who later became his wife. The theory that the impurity defects in the solid cause the X-ray diffuse scattering is called "yellow scattering", and the quantum theory of multi-phonon radiation and non-radiative transition was jointly proposed with Reese; at the same time, Pekar published a parallel theory, which was Internationally known as "Huang-Pekar theory" or "Huang-Ries theory"; proposed the coupling oscillation mode of phonons and electromagnetic waves in crystals, and the equations proposed at that time were called "Yellow equations"; research on semiconductor quantum well super Lattice physics. Established the theory of superlattice optical vibration and published the theory later called "Huang-Zhu Model" by the international physics community.
Huang Kun analyzed in detail the electronic states of the hole bands of the quantum wells and superlattices of III-V compounds, and developed a simple and effective calculation method suitable for the superlattice structure, thereby comparing quantum wells and supercrystals. The effects of the properties of the hole subbands in the lattice structure, the hybridization of the valence band and the external electric field on the absorption of excitons in quantum wells and superlattices have been theoretically calculated. He and his students systematically studied the long-wave optical vibration mode in the superlattice. They proposed a theoretical model that can describe the experimental facts understood so far, and obtained the longitudinal and transverse optical vibrations in one-dimensional and two-dimensional quantum systems. The correct description of the class phantom. Their work has played an important role in understanding the optical properties of semiconductor superlattices, light scattering effects, and the interaction of electrons and lattice waves.
Character Evaluation
Mr. Huang Kun’s most important contribution is the establishment of the five-school joint semiconductor specialization, which has cultivated a batch of talents for the country’s semiconductor science and technology industry, and for the creation and development of China's semiconductor technology and education industry. The establishment and development of the semiconductor industry system has played a pioneering role. His advanced educational ideas such as self-reliance, unity and cooperation, and multilateral struggle for educational resources are always worthy of our study and development.
Commemoration of future generations:
On December 15, 2006, the inauguration ceremony of Mr. Huang Kun's bronze statue co-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 The relevant leaders and their relatives unveiled the bronze statue together.
