“Indium phosphide (InP), a significant III-V semiconductor material, has been extensively studied for its unique optical and electrical properties, with potential applications in optoelectronics, catalysis, and medicine. Researchers have successfully synthesized high-quality InP nanowires and nanopillars using chemical vapor deposition (CVD) and in-situ growth methods, respectively. The nanomaterials were characterized using SEM, EDS, XPS, Raman spectroscopy, and TEM, revealing a high degree of crystallinity and single crystal structure. The growth mechanisms were identified as vapor-liquid-solid (VLS) for nanowires and solid-liquid-solid (SLS) for nanopillars, offering new insights into the controlled preparation and large-scale production of InP nanomaterials.”
