Lab Overview
ONE Lab aims to develop molecular-based material & device solutions for next-generation electronics. Our research focuses on the fundamental transport, device physics aspects of organic and hybrid materials, which form the basis for discovering novel device concepts for emerging technological applications such as sensing and neuromorphic computing. We pursue tackling the underlying complex transport mechanism in organic and hybrid materials in the aim of discovering the best molecular deisgn for different device applications. Concerted approach from different disciplines (materials, physics, chemistry, electrical & chemical engineering) is essential for bringing innovations beyond traditional electronics.
