This book provides an introduction to the world of metamaterials and metasurfaces; artificially engineered materials that can control electromagnetic waves in ways not found in nature. These materials exhibit unusual effects with applications ranging from miniaturised antennas to advanced sensors, energy harvesting, and even future communication systems.

The Physics and Technology of Semiconductor Devices offers a comprehensive treatment of the physical principles underpinning today's semiconductor devices. Tracing the field from its origins and the evolution of Moore's Law, the book offers an integrated perspective on how device physics, materials science and design innovations have shaped and continue to shape the information age.

Transport in Condensed Matter offers a clear and comprehensive introduction to the principles that govern how charge and spin move through condensed-matter systems. The book opens with linear response theory, Green's functions, and the Boltzmann transport equation, essential tools for understanding electronic behaviour in solids. It then develops perturbation theory and diagrammatic methods, followed by a detailed treatment of impurity scattering, a crucial but often neglected ingredient in realistic transport calculations.

Van der Waals Heterostructures and Twistronics: Advances in two-dimensional quantum materials offers an accessible and comprehensive exploration of one of the fastest-growing areas of modern materials science and quantum technology. As research into atomically thin materials continues to reshape the future of electronics and quantum devices, this book examines how atomically thin materials such as graphene, transition metal dichalcogenides, MXenes and related layered systems can be engineered to exhibit extraordinary quantum phenomena through interlayer coupling and twist-angle control.
