Abstract: In moiré crystals resulting from the stacking of twisted two-dimensional (2D) layered materials, a subtle adjustment in the twist angle surprisingly gives rise to a wide range of correlated optical and electrical properties. Herein, we… read more here.

Abstract: Second harmonic generation (SHG) is a prominent branch of non-linear optics (NLO) heavily reliant on conventional bulk NLO crystals. However, the difficulty in downsizing these crystals imposes technical limitations on the future of miniaturized NLO… read more here.
