Biography: Shahab Akhavan completed his B.S. in Materials Science and Engineering and his M.Sc. in Materials Science and Nanotechnology at Middle East Technical University and Bilkent University, respectively. He moved to Cambridge for PhD studies in 2016. He was awarded his PhD in Electrical Engineering from the University of Cambridge in 2020, following which he served as a postdoctoral researcher in the same department until 2021. The same year, he got the position at University College London (UCL) where currently he is serving there as a lecturer at Institute for Materials Discovery. He has published more than 20 journal articles, including in Advanced Materials, ACS Nano, Nano Letters, Nano Energy, Small, etc. He has also delivered keynote and invited talks at major international conferences an发布d received the SPIE Photonics awards and IEEE Electron Device Society award. He has recently been awarded UCL's commercialization grant, focusing on commercialization and potential spin-offs at UCL.

Abstract: The integration of optoelectronic components, such as transistors and phototransistors, into wearable devices made from textiles and papers, presents promising opportunities for diverse applications, including healthcare, physiological monitoring, and sustainable electronics. However, optimizing device performance and refining manufacturing technologies remain significant challenges.

In this presentation, I will summarize our latest developments and showcase a method that allows for the controlled and adaptable rolling of single-layer graphene (SLG) layers, deposited through chemical vapor, onto fibres, resulting in state-of-the-art fibre-based phototransistors [1,2]. Additionally, I will discuss a scalable lithography method for SLG and perovskite on sustainable substrates [3], which are promising approaches for optimizing our devices for wearable, biomedical, and low-power optoelectronic applications.
