About This Course

Discover how III-V semiconductor nanowires are reshaping the landscape of optoelectronics and photovoltaics. This mentor-guided workshop provides a comprehensive understanding of Vapor–Liquid–Solid (VLS) nanowire growth, nanowire-based lasing, and high-efficiency solar cell design.

Participants will explore how nanoscale geometry, band structure, and quantum confinement enable tunable optical and electronic properties. Through real-world case studies, they will learn how nanowire lasers and solar cells achieve superior performance through light confinement, heterostructure engineering, and efficient carrier transport.

Designed for students, researchers, and engineers in nanotechnology, materials science, and optoelectronics, this program bridges fundamental principles with device-level innovations driving next-generation photonic and energy technologies.
