Abstract:
Two-dimensional (2D) materials, with their atomic thickness and exceptional electrical and optical properties, are considered among the most promising candidates for next-generation information devices. They hold great potential for high-performance electronic, optoelectronic, and optical chips and are expected to drive a "green" transformation in chip technology from the ground up. However, the wafer-scale, batch, and functional synthesis of high-quality 2D materials remains a critical challenge for their industrial application.
This talk will present a series of methodological advances by our team in the synthesis of 2D materials. For electronic chips, through interfacial engineering, we have achieved the rapid batch production of 12-inch wafers of high-quality 2D semiconductors, providing the material foundation for large-scale integration of high-performance devices. For optoelectronic chips, by utilizing interfacial coupling to precisely control zero-dimensional quantum dots, one-dimensional semiconductor arrays, and twisted bilayer graphene, we have expanded the photoresponse range and enabled new functional integrations. For optical chips, we have proposed a novel "lattice transport–interfacial epitaxy" strategy to realize the controlled synthesis of rhombohedral-phase 2D crystals with tunable layer numbers and stacking orders, and explored their applications in nonlinear optical frequency conversion and fiber-integrated devices. These studies not only advance chip technology but also open new avenues for developing functional materials and devices for environmental monitoring and energy conversion.
