Isotope-Dependent Optical Moiré Patterns in Twisted hBN
Youngji KimVanderbilt University – Nashville, Tennessee, USA_______________________________________ Twisted two-dimensional van der Waals heterostructures have been widely investigated for their ability to manipulate light-matter interactions. Optical observation of the moirélattice is crucial for understanding the induced long-range periodicity and its impact on the optical and electronic behavior of these heterostructure devices. Furthermore, moiré studies to date…

Twisted hBN as a new platform for moiré engineering
Xiaoqin Elaine LiUniversity of Texas at Austin – Austin, Texas USA_______________________________________ Moiré superlattices are typically created by stacking and twisting two functional layers, such as graphene and transition metal dichalcogenides (TMDs). This process often results in simultaneous changes in electronic and photonic properties as a function of the twist angle, which can impose undesirable constraints.…
