2D materials
We explore 2D materials, such as graphene and transition metal dichalcogenides, for applications in electronics, optoelectronics and integrated photonics. These materials are crystalline and thus of high quality, yet they can be produced at low cost and with large-area dimensions, making them attractive for embedding intelligence into everyday objects.
AI on a chip
We investigate novel materials, devices and systems for neuromorphic sensing by mapping of machine learning algorithms and computational models to circuits and device architectures. The aim of our work is to provide more efficient sensory data processing by embedding intelligence into the sensors themselves.
