This book is a straightforward guide for researchers, engineers, and technology enthusiasts interested in memristors. It covers the fundamentals of memristors, including what they are and how they work, and explores different materials used in them, like binary oxides, perovskites, and new materials like transition metal dichalcogenides (TMDCs). It also explains how memristors are made using methods like physical vapor deposition (PVD) and electrochemical deposition. The book also shows the different types of memristor devices such as non-volatile, spintronic, ferroelectric, polymeric, and molecular memory devices. The book discusses important things like how well memristors work over time, how consistent they are, and how fast they can switch on and off. It also talks about where memristor technology is headed in the future, beyond what's possible with current computer chips.

Memristors have received wide attention due to their futuristic applications such as in neuromorphic computing and memories. The chapter begins with an introduction to memristors thereafter focusing on the classifications.The different switching mechanisms are described in the next section. An overview of the different material systems is presented with a focus on binary oxides and perovskites. Finally, the different fabrication techniques are reviewed, and the structural characterizations are elucidated. The second phase of this chapter describes the role of emerging 2D materials in neuromorphic computing with a special focus on recent developments in memristors, memtransistors, and artificial synaptic devices based on transition metal dichalcogenides (TMDCs). The role of TMDCs in realizing low-power neuromorphic devices is summarized in the following section. Subsequently, the chapter explores the recent advancements in TMDCs-based memtransistors for performing more complex neuromorphic functions.
