F.5 Chan Tsz Yeung, Cheung Hei Ming and Wan Ka Ming participated in the captioned internship programme during July to August 2022.

During the internship, they exfoliated two types of 3D materials into 2D materials and observed the samples under a light microscope. They also stamped two types of 2D materials into heterostructures. Finally, they observed the optical and chemical properties of the materials under a Raman spectroscopy.
