Recently, Chinese scientists have made great breakthroughs in graphene research: SOI materials research group of State Key Laboratory of information functional materials, Shanghai Institute of microsystems and information technology, Chinese Academy of Sciences has successfully controlled the number of graphene layers. The research paper "spectrum adjustable flexible all graphene based field controlled light emitting devices" by Professor Ren Tianling, Institute of microelectronics, Tsinghua University It is the first time to reveal the light-emitting devices which can control the light-emitting wavelength by voltage. Analysts pointed out that, benefited from technological breakthroughs, policy support, industrialization speed-up, industrial 4.0 development and military application, graphene has a huge development space; the A-share graphene plate has a small cumulative growth in the year, and the investment opportunities of related themes deserve attention.

graphene technology is a major breakthrough.

and

graphene has excellent electrical properties, outstanding thermal conductivity and excellent mechanical properties. It is considered as "the magic material that can completely change the 21st century", and has broad application prospects. At present, many countries, including China, are accelerating the research and development of graphene, and high-tech achievements emerge in endlessly. Recently, the SOI materials research group of the State Key Laboratory of information functional materials, Shanghai Institute of microsystems and information technology, Chinese Academy of Sciences has made new progress in the preparation of graphene films with controllable layers. The research group designed Ni / Cu system and introduced carbon source by ion implantation technology. By precisely controlling the dose of implanted carbon, the number of graphene layers was successfully controlled. Compared with the traditional CVD process, ion implantation technology has the advantages of low-temperature doping, precise energy and dose control and high uniformity. The number of single and double-layer graphene prepared by ion implantation is only affected by the carbon implantation dose, and has nothing to do with the gas volume ratio, substrate thickness and growth temperature. In addition, ion implantation technology is compatible with modern semiconductor technology, which helps to realize the real application of graphene as an electronic material in the field of semiconductor devices. In addition, on July 16, the research group of Professor Ren Tianling from the Institute of microelectronics of Tsinghua University revealed for the first time the light-emitting devices which can control the light-emitting wavelength by voltage. Different from the traditional fixed wavelength LED, the light emission wavelength (in a single device) of this new device can be continuously adjustable from 750nm to 450nm, breaking through the existing color synthesis mode of display devices, and is expected to have a revolutionary impact on contemporary display, lighting and communication technology.

focus on graphene theme investment opportunities.

according to incomplete statistics, China's Graphite reserves account for 75% of the world's total reserves, and the output accounts for 72% of the world's total output. It is one of the few minerals with international competitive advantage in China. Benefiting from policy support and speeding up industrialization, graphene has a huge development space. At present, the research and development of graphene is increasing all over the world, and graphene has made breakthroughs in the application of batteries, wearable devices and condensers. Industry insiders believe that with the upgrading of "industry 4.0" as a national strategy, the mass production of graphene will be accelerated and its application prospect will be broad. At the same time, in early 2015, the establishment of graphene military application Committee of China's graphene industry technology innovation strategic alliance also means that the promotion of graphene in the military industry has been accelerated.

Huatai Securities research report pointed out that the state clearly listed new materials as an important strategic emerging industry in the 12th Five Year Plan. The National Natural Science Foundation of China has successively allocated more than 300 million yuan to support graphene related projects, and the state has guided the graphene industry to establish a strategic alliance for technological innovation of China's graphene industry. At the same time, private capital flowed to graphene industry, and the framework of production, teaching, research and application was basically formed. Under the active guidance of industrial parks and venture funds, some entrepreneurs set up companies with technology as capital, and some listed companies take capital as the advantage to intervene in graphene field. In view of the huge application prospect of graphene, it is suggested to pay attention to the relevant listed companies with graphene technology reserves and the thematic investment opportunities brought by the gradual promotion of graphene industrialization. From the perspective of market performance,

and

, the graphene index increased by 46.54% during the year, ranking 99th among 119 concept indexes, with a relatively small increase. Under the background of technological breakthrough, policy support and industrialization acceleration, graphene plate has supplementary momentum. It is suggested that attention should be paid to the listed companies with graphene technology and the thematic investment opportunities brought about by the promotion of graphene industrialization.
