Experimental study demonstrates strain-tunable optical properties in boron phosphide nanowires, highlighting potential for polarization-sensitive photodetection.
Air-stable single-crystalline boron phosphide nanowires with tunable diameters are grown by controlling supersaturation during chemical vapor transport. Strain-dependent Raman spectroscopy reveals strong strain–phonon coupling, while non-centrosymmetry and nanoscale confinement produce anisotropic Raman scattering and polarization-resolved second-harmonic generation. Integration with MoS2 enhances polarization discrimination, enabling high-performance polarization-sensitive photodetection.
