1.1 Goal and mission
To build a world-class international research platform in the fields of graphene electronics and cluster physics, to cultivate for the motherland research talents who are determined to forge ahead and have the spirit of scientific research and innovation, aim at the frontiers of world science, serve the country’s major technological needs, and strive for success. World-class research results.
(1) epitaxial graphene electronics: SiC single crystal from optics to electronics – Preparation and Epitaxial graphene device
epitaxial graphene graphene is an ultra high purity, which is in the induction heating furnace The silicon carbide single crystal grows on the surface of silicon carbide after being heated to a high temperature. Epitaxial graphene nanoelectronics can make full use of the volatility of electrons, so it is very likely to become an ideal material for future quantum computing hardware manufacturing. At the same time, epitaxial graphene electronic devices also have much lower power consumption than traditional silicon electronic devices, and significantly increased operating speed. One of the most noticeable features of the industry is that epitaxial graphene nanoelectronic devices can be directly put into production after a slight improvement on the basis of traditional device processes, without the need to develop new preparation processes. Therefore, epitaxial graphene nanoelectronic devices have great practical value and promotion potential. At present, Nano Center has realized the process flow of cutting, grinding and polishing, hydrogen etching from silicon carbide crystal pillars to 300 micron wafers, and has carried out the preparation and characterization of epitaxial graphene electronic devices.
(2) Physical Cluster: spectrometer means completely independent research to build large
clusters or several tens of micro-aggregate of atoms, typically less than 5 nanometers in size. The research work of the Nano Center based on free clusters is based on exploring its unique electrical, magnetic, catalysis and other properties as the starting point, and the final goal is to serve the development of advanced electronic equipment and new catalytic hydrolysis devices with related research results. Unfolded.
In order to study the electronic structure of free clusters, the lifetime of high excited states and the electronic structure of the inner shell in depth and systematically, we independently designed and built three sets of free cluster research systems and a set of supporting clusters research and study with two-dimensional materials Combined EPI system. What is proud of is that the above four research systems are all independently developed and designed by the center, produced and processed in China, and completely installed, debugged and operated by the teachers and students of the center. Among them, the design concept of a photoelectron spectrometer system based on a small electrostatic ion storage ring for high-resolution full spectrum measurement was first proposed in September 2015 by the executive director of the center, Professor Ma Lei. The completion of this system marks the birth of the world’s first storage ring system for full-spectrum photoelectron spectroscopy of free clusters. At the same time, this system is my country’s first storage ring system with completely independent intellectual property rights. Its process level and resolution will surpass similar large-scale equipment in Europe, filling the gap in the country’s completely independent research and development and construction of large-scale instruments in this field.
(3) Development and research of
flexible electronic devices based on micro-nano processing technology. Flexible electronic devices are used in the fields of biomedical engineering, new energy, environment, information, national defense, etc., with their unique flexibility and ductility, as well as electrical functions. It has a wide range of application prospects. Based on this, the center uses micro-nano processing technology to prepare one-dimensional nano silver wires, two-dimensional graphene nanosheets and other metal polymer functional composite materials, which are used in flexible electronic devices, energy storage devices, and gas sensors. This direction has become a research hotspot and key content in interdisciplinary research. At present, several million yuan has been spent on horizontal projects that have been cooperated in this direction.
