Vision and Interest

The vision is to lead a transformative journey in materials science, establishing clear criteria to uncover the elusive mechanisms governing the Insulator-Metal transition, with a special focus on harnessing the potential of thin films. This endeavor aims to unlock a wealth of materials poised to revolutionize neuromorphic computing. Additionally, it involves developing advanced tools tailored to unraveling these complex mechanisms, thereby enhancing our understanding and capabilities in neuromorphic computing. By seamlessly blending theoretical insights with experimental finesse, this vision promises to usher in a new phase where materials innovation drives remarkable advancements, reshaping industries and propelling scientific progress. Current research focuses on strain engineering in Mott insulators like V2O3, where controlling substrate morphology can reverse strain states and manipulate phase transitions for applications in neuromorphic devices.

Research Areas

Thin films

Thin films are grown using various methods, including chemical vapor deposition (CVD), atomic layer deposition (ALD), and sputtering. CVD involves the chemical reaction of gaseous precursors to form a solid film on a substrate, allowing for high-quality coatings with uniform thickness. ALD provides precise control over film thickness by depositing atomic layers, making it suitable for nanoscale applications. Sputtering uses energetic particles to eject material from a target, which then deposits as a thin film.

Device fabrications

In neuromorphic devices, the focus is on creating hardware that simulates the functions of biological neural networks. This involves using materials like memristors and transistors to replicate synaptic and neuronal behavior. Key techniques include thin-film deposition and lithography, which enable the construction of nanoscale components that facilitate efficient information processing and learning, crucial for advancing artificial intelligence and brain-inspired computing.

2D materials

Two-dimensional layered materials, such as graphene and transition metal dichalcogenides (TMDs), consist of atomically thin sheets. Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, characterized by high electrical conductivity, mechanical strength, and thermal conductivity. In contrast, TMDs are composed of transition metals and chalcogens, featuring distinct electronic properties, including tunable band gaps that can shift from indirect to direct depending on their thickness.
