Ultrafast, Sensitive, and Stable: A Roadmap for Processing and Preserving 2D Hybrid Perovskite Devices

The next generation of optoelectronic technologies operating at the interface between photonics and electronics demands exceptional performance: ultra-broad bandwidth, sub-nanosecond response times, high sensitivity, and stable operation under ambient conditions. Achieving these ambitious targets places stringent demands on the electrical and optical properties of active materials—requirements that only a few existing systems can meet.

Layered 2D organic–inorganic perovskites have recently emerged as a promising class of materials, offering a unique combination of outstanding photophysical characteristics and excellent charge transport properties. Their broader adoption has thus far been hindered by poor environmental stability and high sensitivity to processing solvents, which limit their compatibility with conventional device fabrication techniques.

In this talk, I will present a robust strategy to enhance the resilience of 2D perovskites and demonstrate how top-down semiconductor processing can be used to create high-quality nanoscale structures based on these materials. I will then provide a comprehensive characterisation of their optoelectronic performance, showing that these devices surpass state-of-the-art Si and InGaAs structures. Finally, I will illustrate their integration into real-world signal processing applications, highlighting their potential to reshape the current optoelectronic landscape.
