6英寸二维半导体单晶量产核心技术获突破

Core Insights - The research teams from Southeast University and Nanjing University have made significant advancements in the production of two-dimensional (2D) semiconductor single crystals, overcoming challenges related to carbon contamination, small crystal size, and low mobility through a novel metal-organic chemical vapor deposition technique [1][2]. Group 1: Technological Breakthrough - The introduction of oxygen in the growth process has led to a more efficient reaction, increasing the precursor reaction rate by over 1000 times, which is crucial for the production of high-quality 2D semiconductors [1][2]. - The new method has improved the growth rate of molybdenum disulfide crystals significantly, with average crystal sizes increasing from the nanometer range to several hundred micrometers, facilitating uniform large-area growth [2]. Group 2: Industry Implications - This breakthrough marks a substantial step towards the industrialization of 2D semiconductors, laying a material foundation for their application in integrated circuits, flexible electronics, and sensors [2]. - The research validates the theory that controlling growth dynamics can enhance material quality, indicating a promising future for non-silicon materials in the post-Moore era [2].
