2D van der Waals Layered Semiconductors

This book provides an integrated examination of van der Waals (vdW) layered semiconductors by focusing on the key scientific advances and technological hurdles that shape their path toward real-world applications. Organized around nine major themes—including material growth and heterostructure design, contact engineering, gate dielectrics, device architectures, diluted magnetic, plasmonics and excitonic phenomena, and energy and computing applications—it highlights how progress in each area converges to enable high-performance electronic, optoelectronic, and energy systems. Particular attention is given to persistent challenges such as scalable synthesis, low-resistance contacts, dielectric integration, and reproducible device fabrication, while outlining emerging solutions and design strategies. By linking fundamental insights with device-level implementation, the book presents a cohesive roadmap for transforming vdW semiconductors from promising laboratory materials into reliable platforms for next-generation technologies.
