Third-Harmonic Generation in Crumpled Silicon Nanomembranes

Abstract Silicon nanomembranes provide mechanically compliant devices for strain engineering. Here, we investigate third-harmonic generation in flat and crumpled silicon nanomembranes of 15 and 35 nm using polarization-resolved third-harmonic generation microscopy with ab initio...

Wafer-scale synthesis of WSe 2 for high-performance p-type top-gated transistors and logic circuits

Two-dimensional (2D) transition metal dichalcogenides (TMDs) offer a promising pathway for next-generation electronics due to their exceptional electrical characteristics at atomically thin thickness. Nevertheless, the realization of high-quality p-type 2D-FETs remains a signific...
