, as well as their heterostructures. We study CVD-
growth and performextensivematerial characterization to illuminate the role of dissimilar 2D substrates in the prevention of interior
defects in transition metal dichalcogenides (TMDs), thus uncovering the conditions for anti-oxidation. We further demonstrate the
epitaxial growth of TMDs on hBN and graphene, as well as vertical/lateral heterostructures of TMDs, uniquely forming in-phase
2D heterostructures. This research provides a detailed observation of the oxidation and anti-oxidation behaviours of TMDs, which
corroborate the role of underlying 2D layers in the prevention of interior defects in TMDs. If the technique could be developed
to be highly reliable and high fdelity, it could have a large impact on the future research and commercialization of TMD-based
devices. Furthermore, we develop flexible electrodes and energy storage toward wearable and multifunctional electronics. Here,
we develop a facile fabrication technique utilizing vertically aligned carbon nanotubes (VACNTs), which enables high-throughput
fabrication of flexible supercapacitors. We develop an innovative technique, which facilitates a stable charge/discharge under
varied strains. Our structure shows a high flexibility and stability during stretching up to 20% and bending up to 180 degrees.
These flexible supercapacitors are promising for various flexible electronics applications. Building on these previous results
from 2D material growth and flexible electrodes, our next step is to combine 2D materials with flexible substrates toward next
generation wearable detectors.
