ALL lab is at the forefront of researching two-dimensional layered materials, focusing particularly on semiconductors and metals, with the aim of pioneering the next generation of electronic devices.
Understanding and tailoring the interfaces
Since 2D layered materials are atomically thin, they are highly sensitive to their surrounding environments, the interfaces. These interfaces can dramatically affect the properties and behaviors of low-dimensional materials, leading to changes in their characteristics. Thus, to understand these materials and harness their unique properties, both understanding and tailoring interfaces are essential.
In our research, we delve into the complex world of 2D materials, examining how different interfaces impact their performance. By using advanced interface engineering techniques, we can manipulate these interfaces to create new devices or improve existing properties.
Our work extends beyond merely analyzing the materials; we actively experiment with various methods to modify the interfaces, seeking optimal conditions for various applications. This research not only enhances our fundamental understanding of low-dimensional physics but also opens doors to innovative applications in electronics, and other cutting-edge fields
Large-area applications
For more versatile practical applications, controlling the material properties of large-area low-dimensional films is highly required. These films, made up of extremely thin layers, can have unique characteristics that can be put to use in various ways, but understanding how to manage them over a large area is a critical challenge.
Here, we investigate charge transport mechanisms, focusing on how the interfaces within the large-area films are formed. The way these layers interact can significantly affect how electrical charges move through the material, and that, in turn, affects how the material behaves in different applications.
By tailoring charge transport characteristics using various interface engineering techniques—such as doping, or modulating stacking structures to change how the layers are arranged—we can enhance or modify these materials' properties.
This in-depth exploration allows us to develop a comprehensive understanding of these fascinating materials, paving the way for innovations in technology ranging from electronics to energy solutions. Our work stands at the forefront of a field full of potential, offering new insights and possibilities for the future.
EMI shielding
As mobility technology rapidly grows, the need for EMI (Electromagnetic Interference) shielding has become paramount. This shielding is vital for protecting human lives and property from unwanted accidents that can occur due to EMI from various sources, such as wireless communications, industrial equipment, or high-energy batteries in electric vehicles.
Conductive 2D layered materials are emerging as strong candidates for EMI shielding. These materials offer several advantages: they are lightweight; they are highly conductive, allowing for effective interference blocking; and they are mechanically robust, ensuring durability.
We are engaged in cutting-edge research to develop secure EMI shielding layers using these 2D materials. Our focus extends to a wide range of state-of-the-art mobility solutions, such as electric cars, drones, space rovers, and Urban Air Mobility (UAM) vehicles.
Our work represents a significant step forward in both material science and mobility technology, opening doors to innovative applications and contributing to the safety and efficiency of next-generation transportation.
