突破核心技术！二维半导体量产迎来关键进展

Core Insights - The research teams from Southeast University and Nanjing University have achieved a significant breakthrough in the mass production of two-dimensional (2D) semiconductor single crystals using metal-organic chemical vapor deposition technology with an oxygen-assisted strategy [1][2]. Group 1: Technological Advancements - The new method addresses traditional challenges in 2D semiconductor production, such as carbon contamination, small crystal domain sizes, and low mobility [1]. - By introducing oxygen into the growth process and innovatively designing a pre-reaction chamber structure, the energy barrier for reactions was significantly lowered, increasing the precursor reaction rate by over 1000 times [1]. Group 2: Production Improvements - The new approach has dramatically enhanced the growth rate of molybdenum disulfide crystal domains, increasing the average size from the nanometer scale to several hundred micrometers, and ensuring ordered alignment along specific crystal directions [1]. - This advancement resolves the mass production challenge of achieving uniform growth over large areas and effectively suppresses the formation of carbon-containing intermediates, thereby eliminating carbon contamination issues [1]. Group 3: Industry Implications - This breakthrough lays a material foundation for the large-scale application of 2D semiconductors in integrated circuits, flexible electronics, and sensors [2].
