Raman spectroscopy: contributions to the SPQEO journal

This editorial highlights the focus of Semiconductor Physics, Quantum Electronics & Optoelectronics (SPQEO) on the achievements of Raman spectroscopy (RS) in addressing complex challenges in modern semiconductor physics. Built upon the foundational principles of the classical Raman effect, RS has evolved into a powerful diagnostic technique within materials science, quantum electronics, and optoelectronics. Its inherent advantages—including non-destructive probing, remote sensing capabilities, high spatial resolution, and rapid phase and composition identification—have driven its widespread adoption. Furthermore, breakthroughs such as Surface-Enhanced Raman Scattering (SERS) have pushed the boundaries of sensitivity, enabling single-molecule detection through enhancement factors reaching 10^14–10^15.
