For decades, the relentless miniaturization of silicon transistors has powered the rise of modern computing. But as silicon approaches its physical scaling limits, researchers are turning to new classes of materials to keep Moore’s Law alive. Now, a team from Fudan University in Shanghai has achieved a major technological breakthrough: they have successfully created the world’s first functional hybrid chip that combines 2D materials directly with conventional silicon circuitry.

Their achievement, published in Nature on October 9, 2025 (DOI: 10.1038/s41586-025-09621-8), could mark the dawn of a new era in microelectronics — enabling ultra-fast, energy-efficient memory systems and processors that surpass the capabilities of today’s silicon chips. The work was reported by TechXplore (original article).

🔬 ATOM2CHIP: Bridging the Atomic and the Silicon Worlds

The key to this innovation lies in a fabrication technique called ATOM2CHIP. The researchers developed a method to grow atomically thin 2D memory materials directly onto standard silicon wafers, while ensuring seamless communication between the ultra-thin active layer and the bulkier silicon circuitry beneath.

Previous attempts to integrate 2D materials like graphene, MoS₂, or h-BN faced daunting challenges. Although these materials exhibit remarkable electrical and optical properties, building reliable complex circuits — especially memory architectures — on top of them has proven difficult. Interfacing 2D layers with conventional CMOS processors has been one of the most persistent obstacles to commercialization.

By solving the interconnection problem, ATOM2CHIP unlocks the possibility of scaling chips down to atomic thickness without losing compatibility with the semiconductor industry’s silicon infrastructure. The Fudan team also engineered special packaging layers to protect the delicate 2D materials from static, heat, and mechanical stress — key factors for real-world reliability.

⚡ Real Performance: MHz Speeds and Full System Tests

Unlike many academic prototypes that remain proof-of-concept devices, this chip underwent full system-level testing. The researchers demonstrated reliable operation at clock speeds of 5 MHz, using a rigorous checkerboard programming platform to verify data integrity across the entire memory array.

The result: a fully functional flash memory chip just a few atoms thick, integrated with silicon logic, capable of performing complex tasks with reduced power consumption and improved speed compared to traditional memory modules.

🌐 Why 2D–Silicon Hybrids Matter for the Future of Computing

The integration of 2D materials with silicon could dramatically extend Moore’s Law beyond its conventional limits. Two-dimensional materials like transition metal dichalcogenides (TMDs) offer properties — such as high carrier mobility, tunable bandgaps, and atomic thickness — that can potentially enable ultra-dense memory and logic devices.

In the broader landscape, this breakthrough positions 2D–silicon hybrid chips as a key enabling technology for future AI accelerators, neuromorphic computing architectures, and high-performance data centers. It could also accelerate the development of flexible and wearable electronics, where ultrathin and low-power components are essential.

The research underscores how academic innovation is aligning with industry’s roadmap: instead of replacing silicon outright, hybrid architectures combine the best of both worlds — the maturity and scalability of silicon manufacturing with the superior physics of emerging materials.

🚀 Looking Ahead

While significant challenges remain — particularly in large-scale manufacturing and integration with existing chip foundries — this work by Liu and colleagues sets a powerful precedent. As the industry grapples with the slowdown of traditional scaling, such hybrid chip architectures may become the foundation of the post-silicon era.

AI Tools for Chemistry: The ‘Death’ of DFT or the Beginning of a New Computational Era?

Image
For decades, Density Functional Theory (DFT) has been the workhorse of quantum chemistry and materials modeling. From predicting electronic structures to optimizing molecular geometries, DFT has powered countless breakthroughs in fields as diverse as catalysis, materials design, and condensed matter physics. But recent announcements in the scientific community have caused ripples: is DFT “dead” — or is this simply the dawn of a new computational era powered by artificial intelligence ? The Shock of Declaring a Field “Dead” The provocative statement came during the EuChemS Inorganic Chemistry Conference , where theoretical chemist Markus Reiher announced the “death of DFT.” His claim wasn’t about obsolescence in a literal sense, but about a paradigm shift: AI models can now deliver DFT-level accuracy at a fraction of the cost , fundamentally changing how chemists approach molecular modeling. This echoes previous moments in scientific history where disruptive technologi...

Quantum Chemistry Meets AI: A New Era for Molecular Machine Learning

Image
In a powerful leap forward for computational chemistry and materials design, researchers from Carnegie Mellon University have developed a new kind of molecular machine learning model—one that goes beyond simplistic molecular graphs and integrates fundamental principles of quantum chemistry. Their work, published in Nature Machine Intelligence , could radically enhance our ability to predict chemical behavior, optimize catalysts, and discover new drugs, all while using less data and gaining more scientific insight. The Problem: Traditional Molecular Representations Fall Short Molecular machine learning (ML) models underpin key processes in drug discovery, materials science, and catalysis. However, most existing models use simplified representations such as SMILES strings, 2D graphs, or coordinate matrices. These techniques often lack the quantum-chemical information that governs how molecules truly behave—particularly electron interactions that define reactivity, stability, and...
