Descripción del proyecto
Láseres bombeados eléctricamente de alto rendimiento basados en perovskitas de haluro metálico
Gracias a su capacidad para procesarse fácilmente en películas delgadas, los semiconductores procesados en solución son muy prometedores para el desarrollo de láseres de película delgada necesarios para los circuitos fotónicos integrados en múltiples aplicaciones, como la informática avanzada. Los avances recientes en láseres de perovskita bombeados ópticamente y los diodos emisores de luz de perovskita de alto rendimiento auguran un gran potencial para desarrollar perovskitas en una nueva generación de materiales para láseres bombeados eléctricamente. En el proyecto LEAP, financiado con fondos europeos, se adoptará un enfoque holístico para abordar los retos críticos del desarrollo del láser de perovskita de haluro metálico. Se sintetizarán nuevos materiales de perovskita que, después, se probarán con métodos de espectroscopia avanzados. Además, se evaluarán diferentes tipos de heteroestructuras de pozos cuánticos de perovskita para su uso como medios de ganancia, que utilizan mecanismos totalmente diferentes para alcanzar umbrales bajos.
Objetivo
Electrically pumped lasers are considered as a holy grail in the field of optoelectronics. Despite the success of lasers based on expensive epitaxially grown semiconductors, low-cost solution-processed semiconductors provide new opportunities to significantly expand the applications of lasers. On one hand, low-cost and scalable deposition can meet increasing demand of using lasers in consumer electronics. On the other hand, solution-processed semiconductors can be easily proceeded into thin films, providing great promise to develop thin-film lasers which are required for highly integrated photonics chips in advanced applications.
A superstar in the family of solution-processed semiconductors is metal halide perovskites, which have shown great success in a range of optoelectronic applications. Especially, recent breakthroughs on optically pumped perovskite lasers and high-performance perovskite light-emitting diodes indicate great potential of developing perovskites into a new generation of materials for electrically pumped lasers.
This project has the ambitious goal to realise solution-processed electrically pumped perovskite lasers. I will take a holistic approach, where novel concepts are proposed to address critical challenges on the development of perovskite lasers. Both type-I and type-II perovskite quantum well heterostructures, which utilise fundamentally different mechanisms to reach low thresholds, will be developed as the gain media. Edge-emitting devices based on these new perovskite gain media will then be coupled into rationally designed cavities for lasing actions. At the core of the research is the synthesis of new perovskite materials, combined with advanced spectroscopic characterizations and device/cavity development. This project makes use of recent advances in perovskite optoelectronics to create a new paradigm for electrically pumped perovskite lasers, and will open up new possibilities to revolutionize the current laser technology.
