Title: Colloidal III-V Quantum Optoelectronics: Exploring Novel Materials and Applications

Time: March 27, 2024, 16:00 - 17:00 


Abstract: This talk will review recent advances in colloidal quantum dots (QDs), with a particular focus on III-V systems. Beginning with a brief introduction, we examine three major challenges facing the QD community. The first part explores the synthesis of innovative eco-friendly QDs, covering their synthesis and potential applications. Within this section, we focus on emerging materials such as novel indium phosphide-based heterostructures and their use in optoelectronic devices and interfaces. We then examine QDs that emit in the infrared spectrum, with particular emphasis on lesser-known materials such as indium antimonide and indium arsenide. This section highlights the first development of efficient, stable, and fully compliant near-infrared LEDs based on QDs. Finally, we address additional challenges related to the sustainability of QDs, emphasizing issues of photostability and scalability.

Bio: Houman Bahmani Jalali has been a senior researcher in the photonic nanomaterials research line at the Italian Institute of Technology (IIT) since April 2022. He was awarded the Marie Skłodowska-Curie Individual Fellowship to conduct research on fully RoHS compliant infrared LEDs based on colloidal quantum dots. Prior to his current position, he received his Ph.D. from Koç University in 2020. His Ph.D. thesis titled “Novel Biocompatible Quantum Dots and Nanoengineered Assemblies for Optoelectronic Neural Interfaces” was awarded as the “Best Doctoral Thesis of 202”; by the Council of Higher Education of Turkey. His research is mainly focused on the chemistry and physics of colloidal quantum dots, especially III-V systems for optoelectronic applications. He has authored more than 30 publications in Q1 journals.
