简介：
For the development of modern information technologies, it is critical to solve applied problems both in the field of high- speed transmission, processing and storage of data, and in the field of displaying information and controlling optical signals. One of the urgent tasks is the creation and development of technology for the formation of tunable multilevel integrated logic circuits, including optical ones, for the implementation of neuromorphic computing. The key problem of this technology is the creation of active materials of optimal chemical composition that make it possible to accurately realize multilevel structural states.
The project proposes to implement this technology on the basis of reversibly reconfigurable phase-changing chalcogenide thin-film structures due to a directed change in the structural and, accordingly, physico-chemical properties of the surface layers, as well as a controlled change in morphology and the creation of nanoscale objects. Achieving the planned results will significantly increase the degree of integration, reliability and energy efficiency of the created neuromorphic computing systems, and the development of all-optical multilevel elements will form the basis for further improving the performance of computer technology by reducing delays associated with the electrical method of storing and transmitting data, including those caused by RC delay , and as a result will ensure further development of computer and information technologies.
Thus, the purpose of this study is the development and formation of materials with precise structure control and approaches to the creation of scalable reversely reconfigurable elements, including those for neuromorphic computing systems, using surface engineering of chalcogenide semiconductor thin-film structures.
The project will be implemented by teams from the Russian Federation and Peoples' Republic of China under the leadership of Kolobov A.V. and Yan Cheng, who are leading scientists in the development of reconfigurable disordered semiconductor thin-film structures using modern analytical equipment and Megascience class facilities. The team will include both established experts, who are world-class leading scientists, and perspective young scientists-researchers.
Within the framework of scientific research, for the first time, the complex influence of parameters, including crystallization mechanisms, on structural transformations in phase-changing chalcogenide thin films and multilayer heterostructures under ultrashort laser exposure will be theoretically and experimentally studied, and the switching characteristics and the accompanying change in structural/optical/electrophysical parameters will be determined. Based on the results of joint research by teams from the Russian Federation and China, the material that is optimal in terms of functional properties will be selected and methods for the formation and erasure of intermediate states in thin films based on it will be developed. The results obtained will be tested on T-structures for electrical storage devices with the topological size of the bottom electrode of 190 nm, 90 nm and 50 nm (at present, microelectronics production with 90 nm standards has been implemented in the Russian Federation and the possibility of creating elements according to 65 nm standards has been demonstrated), which will be manufactured by a team from the PRC, as well as on non-volatile fully optically reconfigurable elements, which will be prepared by a team from the Russian Federation.
The work will make it possible to localize in the Russian Federation the basic technologies for creating multilevel non-volatile elements for neuromorphic computing, compatible with silicon microelectronics technology and adapted to the capabilities and tasks of modern manufacturers of electronics and nanophotonics devices with the support of partner enterprises interested in the proposed developments and bringing the technology to licensed level.
