Two-Dimensional Electronics - Prospects and Challenges

The present book is divided into two parts. Part I comprises four chapters which review the current state of the art in different areas of research on 2D materials and devices. Chapter 1 provides an excellent overview of the status of 2D material synthesis and puts special emphasis on the scalability of the discussed techniques and the attainable 2D material quality. Chapter 2 presents an overview on recent progress in the field of flexible graphene devices and describes a flexible graphene-based radio frequency receiver operating at 2.4 GHz. In Chapter 3 a thorough overview on the application of 2D materials in optoelectronics is given and Chapter 4 comprehensively discusses gas sensors made of 2D materials. The eight chapters of Part II deal with specific important aspects of 2D materials and devices. Chapter 5 describes theoretical investigations on the stability and electronic structure of monolayer TMD (transition metal dichalcogenide) alloys and in Chapter 6 the thermal conductivity of graphene nanoribbons is studied by molecular dynamics simulations. Chapter 7 presents the results of experimental investigations on the visibility of exfoliated TMD and black phosphorus flakes. The following three chapters are devoted to the simulation of advanced graphene transistors: Chapter 8 deals with the effects of band-to-band tunneling and edge roughness on the behavior of graphene nanoribbon MOSFETs. In Chapter 9 recent results on the steady-state and RF operation of graphene nanoribbon transistors are presented and in Chapter 10 a compact modeling approach for a novel graphene-based transistor type (called graphene base transistor) is elaborated. The last two chapters of the book deal with several aspects of the application of graphene in non-transistor devices: Chapter 11 presents the analysis of graphene nanomechanical mass sensors and Chapter 12 provides a discussion on graphene-based field emitters.
