A study published on March 25, 2026, reveals that silicon nanospheres significantly boost the efficiency of second-harmonic generation (SHG) in the semiconductor WS₂ by a factor of 40.
This enhancement is notable as it preserves the circular polarization information, which is crucial for applications leveraging the valley degree of freedom in two-dimensional materials.
The implications of this research extend to potential advancements in optoelectronics and quantum computing, where efficient SHG processes are vital for device performance.
