Optical Signature of Moiré Superlattices Formed by Twisted SrTiO Membranes
T. A. M. Ragib Shahriar, Fumikazu Murakami, Xing He +11
Moiré superlattices formed at the interfaces of mismatched lattices have attracted significant interest over the past decade due to their large tunability of band parameters and in…
Chip-Scale Aligned Chiral Carbon Nanotubes Exhibiting Giant Second Harmonic Generation
Rui Xu, Jacques Doumani, Viktor Labuntsov +16
Chiral carbon nanotubes (CNTs) are direct-gap semiconductors with optical properties governed by one-dimensional excitons with enormous oscillator strengths. Each species of chiral…
Large effective magnetic fields from chiral phonons in rare-earth halides
Jiaming Luo, Tong Lin, Junjie Zhang +5
Time-reversal symmetry (TRS) is pivotal for materials optical, magnetic, topological, and transport properties. Chiral phonons, characterized by atoms rotating unidirectionally aro…
Phase Stability of Hexagonal/cubic Boron Nitride Nanocomposites
Abhijit Biswas, Rui Xu, Joyce Christiansen-Salameh +21
Boron nitride (BN) is an exceptional material and among its polymorphs, two-dimensional (2D) hexagonal and three-dimensional (3D) cubic BN (h-BN and c-BN) phases are most common. T…
Non-linear optics at twist interfaces in h-BN/SiC heterostructures
Abhijit Biswas, Rui Xu, Gustavo A. Alvarez +24
Understanding the emergent electronic structure in twisted atomically thin layers has led to the exciting field of twistronics. However, practical applications of such systems are…
