Multifunctional Heterostructure Thin Films Handbook

This book provides a comprehensive guide to heterostructure thin films and multifunctional nanomaterials, highlighting how the stacking of dissimilar materials enables interface-driven properties that surpass those achievable in bulk systems. It covers fundamental concepts such as band alignment, strain and charge coupling, and built-in fields, alongside advanced synthesis techniques including pulsed laser deposition, atomic layer deposition, molecular beam epitaxy, and chemical/physical vapor deposition. The volume emphasizes state-of-the-art characterization methods, ranging from structural and compositional analyses to electrical, optical, and in-situ approaches, as well as AI-assisted multimodal techniques to probe interfaces and defects. Functional phenomena, including ferroelectricity, magnetoelectric coupling, spintronic effects, thermoelectric and piezoelectric responses, are closely tied to device applications such as non-volatile memories, sensors, actuators, solar cells, and flexible/wearable electronics. Case studies on multiferroic, van der Waals, and hybrid organic–inorganic systems illustrate the power of interface engineering. Chapters on inorganic perovskite solar cells, thin-film sensors, and PAAO-based plasmonic metamaterials demonstrate scalable, application-driven innovations. Concluding perspectives explore AI-assisted optimization, quantum and topological heterostructures, and strategies for scalable, energy-efficient device integration, offering a roadmap for future research in multifunctional thin films. Multifunctional Heterostructure Thin Films Handbook: Fundamentals, Fabrication, and Device Applications serves as a valuable resource for researchers, engineers, and graduate students working at the forefront of materials science, nanotechnology, and the development of next-generation devices.
