Exploring exciton phenomena

Welcome to Andrés Granados del Águila Laboratory, part of the Institute of Materials Science at the University of Valencia.

Our research focuses on the microscopic behaviour of excitons (X), coupled electron-hole pairs, in emergent quantum materials. We are particularly fascinated by their collective behaviour in two-dimensional (2D) semiconductors, such as TMD monolayers, as well as in single-photon emitters. To unlock this exciting physics, we investigate the resulting strong optical and transport nonlinearities by developing novel samples arquitectures and experimental techniques.

Recent breakthroughs in exciton research

Research highlights

Two-dimensional (2D) semiconductors hold great potential as coherent light sources for photonic integrated circuits. However, the conventional integration of 2D materials on to silicon photonics introduces significant structural and optoelectronic drawbacks, hindering the practical realization of coherent photonic circuits. In this work, we introduce the concept of a van der Waals photonic integrated circuit, which is a complete on-chip optical system fabricated entirely from a van der Waals heterostructure, showcasing the potential of 2D materials for advanced nanophotonics applications.

We sincerely congratulate Prof. Ren and all co-authors for this outstanding contribution to the field of nanophotonics.
