Quantum Materials & Devices Lab
Led by Prof. Jae-Hyun Lee, our laboratory explores the full spectrum, from the discovery and synthesis of quantum van der Waals (vdW) materials to the fabrication and performance evaluation of advanced semiconductor devices. Beyond fundamental research, we pursue vdW-based technologies for diverse applications, including:
Discovery and synthesis of novel vdW quantum materials
Nanoelectronics, such as optoelectronic devices and flexible electronics
3D-stacked memory semiconductors (e.g., 3D DRAM)
vdW-enabled composite structures for functional applications across electronics, sensing, and corrosion.
Our goal is to bridge the gap between state-of-the-art van der Waals (vdW) materials research and impactful real-world technologies.
van der Waals Quantum Materials
We explore and synthesize a wide variety of van der Waals quantum materials, including two-dimensional semiconductors (e.g., MoS₂, WS₂), topological insulators, and semimetals. By developing precise bottom-up growth techniques and interface control strategies, we aim to uncover new physical phenomena and enable materials platforms that underpin advanced semiconductor and optoelectronic technologies.
Nano-electronics
Our lab develops nanoelectronic devices that exploit the unique properties of vdW materials. Research topics include high-performance optoelectronic devices, flexible and stretchable electronics, and heterostructure-based components for ultrafast, low-power circuits. These efforts bridge fundamental materials science with next-generation electronic and photonic systems.
3D Stacked Semiconductors
We investigate three-dimensional stacked semiconductor architectures for future memory and logic devices, such as 3D DRAM and heterogeneous integration technologies. By leveraging vdW interfaces and atomic-scale precision, we aim to overcome scaling limits in conventional semiconductor processes and unlock new possibilities for high-density, high-performance computing hardware.
Functional Applications
Beyond conventional electronics, we apply vdW materials and hybrid structures to functional applications across diverse fields. This includes broadband photodetectors, advanced sensing platforms, and composite materials that integrate vdW nanomaterials with other functional components, enabling breakthroughs in photonics, energy, and smart systems.
