Layer number and surface condition of exfoliated InSe was found to play a vital role in the carrier lifetimes and mobilities
Dr. Kung-Hsuan Lin and Director Chia-Seng Chang at IoPAS led to investigate the ultrafast phenomena in exfoliated InSe. The layer dependence on carrier recombination rate in freshly exfoliated and air-oxidized InSe indicates that the thickness and surface condition should play an important role to the performance of devices based on few-layer InSe. The carrier lifetime or mobility decreases with decreasing thickness due to the surface recombination. This work was published in Nanoscale (2023, Issue 7) and featured in its back cover.
