Defect-Mediated Chemical Modification of Semiconducting 2D Metal Chalcogenides

Written by Jahlani Odujole

Qing Hua Wang and her research team were aiming to create nanoscrolls by using a novel functionalization method. Nanoscrolls are less popular than carbon nanotubes, which have gained recent popularity. She presented two videos of movement (at 55 K and 355 K) to demonstrate how functionalization can be used to attach proteins. The researchers determined that a combination of air plasma and water vapor was essential for rolling nanoscrolls onto a SiO2 substrate. Different bonding energies were also observed for different orientations of the crystallographic lattice structure. This research allows for the chemistry of two-dimensional (2D) materials to be used to modify properties. The analysis of defects was presented as a means to characterize and gain a better understanding of 2D materials. The ability to grow chains of molecules form the basis of their future work.
