Abstract: Transformative energy technologies will provide strong strategic support to the realization of peaking carbon dioxide emissions before 2030, and achieving net zero carbon emissions before 2060. Reducing the dependence on fossil fuels by saving energy and reducing emissions from the source is essential to achieve the double-carbon target as soon as possible. Songshan Lake Materials Laboratory is working on key materials to develop solar-battery power systems and electrification of transportation energy to return coal, oil, and natural gas from fuels to materials. This study focuses on introducing the research team of its New Energy Materials and Devices R&D Center with the whole chain innovation mode from research to technology transfer/transformation. Example works of new materials for High Efficiency Crystalline Silicon Solar Cells Group, Li-ion Battery Materials Group, Flexible & Zinc Battery Group are introduced. To get through “the last mile” of technology transformation, research projects and pilot lines have been set up to make new energy materials and devices into products in the past three years, and work together with industrial partners in an innovative workshop cluster model. It is suggested to make overall planning, provide stable support to the research and development, and create a cluster development model with R&D center-innovative workshops#2;industrial parks.

Abstract: The rapid development of the information society puts forward an ever-increasing urgent need for information storage, processing, and transmission capabilities. With the ending of Moore's Law, the semiconductor industry urgently needs to find new solutions. Low#2;dimensional materials are considered to be a new breakthrough in the semiconductor industry in the post-Moore era, because of the size characteristics of atomic-level thickness, the structural advantage of no dangling bonds on the surface, and the sensitivity to electrical and optical control methods caused by a large specific surface area. Songshan Lake Materials Laboratory has introduced a group of top scientists and established a low-dimensional materials team. The research of the team, based on basic science and guided by engineering applications, focuses on tackling key issues. The goal is to achieve world-class influential scientific research results, and to deploy China low-dimensional materials industry.

Abstract: Integrated photonics are fast-developing research field for next generation information technology. Current silicon photonic integrated chips strongly benefit from low-cost and high-density integration properties of existing CMOS technology. But limited by the physical properties of silicon, it is not a perfect material for different types of optoelectronic devices, such as laser sources, modulators, and infrared detectors. Therefore, heterogeneous integration is proposed by combining the advantages of CMOS process and superior opto-electric properties of heterogenous material systems, that can be an essential step towards next generation integrated optoelectronic chips. Here, this paper introduces the rapid progress of integrated photonics nationally and worldwide, while discusses the potential directions and opportunities in this field.

Abstract: The development of metallic materials is closely correlated to the civilization of human being. Amorphous alloys with long-range disordered atomic microstructure, unique physical and mechanical properties, are advanced and novel metallic materials which have diverse industrial applications. Recently, the scientific research, new system development, and industry applications of the structural disordered alloys such as amorphous alloys and high entropy alloy are fast developing, and have significant influence on fields such as the desgin and development of metallic materials, structural materials, green materials, magnetic materials, catalytic materials, and information materials. In this article, we review the history, the development trends, the fundamental scientific issues, applications and basic research chances and challenges of amorphous and related structural disordered alloys. The role of Chinese scientists in the development of the disordered alloys is evaluated and introduced. We propose the corresponding implication and suggestions on the future development and applications of the fast#2;moving field and the advanced metallic materials in China.

Abstract: The whole-chain science and technology innovation involve scientific research institutions, enterprises, governments, and even the whole society. The goal is to produce independent innovations in key and core technologies and to establish systems for technological standards, so as to promote industrial development. The ability and efficiency of the whole-chain science and technology innovation is an important criterion in measuring an innovative social ecology, with the innovation cycle being one of the important criteria for characterization. It shall be an important driving force for the whole-chain science and technology innovation if national research organizations can have a comprehensive layout in a specific field, covering basic research, applied basic research and even engineering. The second half of the whole-chain science and technology innovation is a process in which “innovative achievements” and “entrepreneurs” are jointly engaged in market promotions and evaluations. In order to further shorten the cycle, collaborations of certain scientists and entrepreneurs should be encouraged, the flow and coordination of various innovative resources in the market should be accelerated.
