He is also director of the National Key Laboratory of Solid State Microstructure, one of the chief scientists of the 973 Program and plays a leading role in the MOE Program for Changjiang Scholars and Innovative Research Team. Chen’s field of research is material physics and chemistry. His research focuses on artificial band gap materials; the design, preparation, physical and optoelectronic properties of multilayered-thin-film acoustic superlattices and ferroelectric/dielectric films. Among his research achievements, “The Realization of Sound Wave’s Double Negative Refraction in a Sonic Crystal” was selected into “The Top Ten Big News Items on China’s Basic Research” in 2007, and “Ionic-type phononic crystal” was selected into “The Top Ten Big News Items on China’s Basic Research” in 1999. Chen has won the first prize of “The 2006 MOE Natural Science Awards” (the fourth recipient), the first prize of “The 2013 MOE Natural Science Awards” (the first recipient), the second prize of “The 2015 National Natural Science Awards” (the first recipient), and “The 2012-2013 Year YE Qisun (YEH Chi-sun) Prize” awarded by the Chinese Physics Society . He has published 150 papers, including SCI papers in Nature, Physical Review Letters, and Science. He has 11 Chinese invention patents and 2 US patents. One of the Ph.D. dissertations he supervised was selected into “The Top 100 Outstanding Doctoral Theses” and another was nominated. Research interest Physical properties of materials depend not only on the components of the materials but also on their microstructures. Research over the last 20 years has shown that the artificial microstructures of materials can greatly improve their optical, acoustic, mechanical and thermal properties, and this has formed a new wave of research on artificial microstructure physics and materials, particularly the photonic crystal/phononic crystal and acoustic metamaterials. With purposeful design, artificial microstructure materials can gain novel properties beyond component materials and homogenous materials, and make unbelievable breakthroughs in mechanical, thermal, optical, electrical and magnetic functions. Chen and his research team have used artificial microstructure design to tailor phononic and photonic energy band and have made original achievements in areas of phononic crystal and other artificial microstructure materials. They have discovered a new law of refraction of phononic crystals, achieving the negative refraction of the first and second energy band. This has led them to propose and prove the double negative refraction effect caused by the overlapping band theory, thus realizing the focusing dual imaging of sound-wave super lens. They have also established a new principle for wave vector transition mechanisms to realize one-way wave propagation and successfully developed a broadband, non-threshold new type of sound-wave diode prototype device. Besides, having expounded the key physical function mechanisms of surface acoustic evanescent wave in the sound wave’s abnormal transmission and self-collimation effect, they has proved the abnormal transmission effect of sound waves for the first time and expanded the research fields of sub-wavelength materials and devices. The team has also worked with California Institute of Technology in design and for the first time observed the spontaneous symmetry breaking of parity-time in Si-based photonic chips and realized the one-way propagation and manipulation of 1.55 um communication band lightwave. The team, beginning with microstructure design, has prepared the 0-3 microstructure material with ZnO distributed at the grain boundaries of lead-free piezoelectric material and solved the problem of thermally stimulated depolarization which has long limited the actual use of lead-free piezoelectric materials.
