Led by Chunsen Liu at Fudan University in Shanghai, the team has successfully demonstrated how 2D materials can be combined with traditional silicon chips. As a result, their work, published in the journal Nature, bridges the gap between the theoretical potential of 2D materials and their practical application in real-world devices. Consequently, this breakthrough opens up new possibilities for integrating cutting-edge materials into mainstream technology.
For decades, engineers have been focused on shrinking the circuits in silicon chips. However, this approach is now reaching its physical limits. The development of 2D materials, which are just a single layer of atoms thick, presents a promising solution. However, integrating these fragile and unstable materials with conventional processors has posed significant challenges.
Overcoming Challenges: The Atom2Chip Technology
To address these challenges, the Fudan University team introduced a new technology called Atom2Chip. This innovation includes several key advancements to ensure the successful integration of 2D materials with silicon chips. The Atom2Chip technology features a full-stack on-chip process that allows a monolayer of molybdenum disulfide, a 2D material, to adhere to the rough surface of a CMOS chip. Special packaging techniques protect the fragile atomic layer, ensuring its stability.
The researchers also developed a cross-platform system that enables seamless communication between the 2D circuits and the mature CMOS platform. This breakthrough is not just a prototype; the team has created a fully functional 1-Kb 2D NOR flash memory chip that can perform complex. Instruction-driven operations.
In testing, the hybrid chip achieved an impressive clock speed of 5 MHz and demonstrated quick programming and erasing speeds of just 20 nanoseconds. Moreover, it consumed minimal energy, highlighting its potential for energy-efficient, high-performance memory devices.
