Strain engineering is an attractive method to induce and control anisotropy for polarized
optoelectronic applications with two-dimensional (2D) materials. Herein, we have …

The stacking of few layers of transition metal dichalcogenides (TMDs) and their
heterostructures allows us to create new structures, observe new physical phenomena, and …

Transition-metal dichalcogenides exhibit extraordinary optical nonlinearities, making them
promising candidates for advanced photonic applications. Here, we present the microbial …

Metamaterials and plasmonic structures made from aluminum (Al) have attracted significant
interest due to their low cost, long-term stability, and the relative abundance of aluminum …

Second-harmonic generation (SHG) is a nonlinear optical effect enhanced by broken
crystallin symmetry and is very sensitive to electronic structures. SHG has recently been …

We calculate the spectrum of interlayer neutral excitons in transition-metal-dichalcogenide
WeSe $ _2 $/MoSe $ _2 $ heterobilayers in the $ R $-stacking configuration. Most saliently …

Upon excitation by an electromagnetic field, metallic nanomaterials will produce highly
localized areas of electromagnetic enhancement, a phenomenon known as localized …
