Book Description
This book discusses analytical approaches and modeling of the breakdown voltage (BV) effects on graphene-based transistors. It presents semi-analytical models for lateral electric field, length of velocity saturation region (LVSR), ionization coefficient (α), and breakdown voltage (BV) of single and double-gate graphene nanoribbon field effect transistors (GNRFETs). The application of Gauss’s law at drain and source regions is employed in order to derive surface potential and lateral electric field equations. LVSR is then calculated as a solution of surface potential at saturation condition. The ionization coefficient is modelled and calculated by deriving equations for probability of collisions in ballistic and drift modes based on the lucky drift theory of ionization. The threshold energy of ionization is computed using simulation and an empirical equation is derived semi-analytically. Lastly avalanche breakdown condition is employed to calculate the lateral BV. On the basis of this, simple analytical and semi-analytical models are proposed for the LVSR and BV, which could be used in the design and optimization of semiconductor devices and sensors. The proposed equations are used to examine BV at different channel lengths, supply voltages, oxide thickness, GNR widths, and gate voltages. Simulation results show that the operating voltage of FETs could be as low as 0.25 V in order to prevent breakdown. However, after optimization, it can go as high as 1.5 V. This work is useful for researchers working in the area of graphene nanoribbon-based transistors.

Book Description
Tremendous innovations in electronics and photonics over the past few decades have resulted in the downsizing of transistors in integrated circuits, which are now approaching atomic scales. This will soon result in the creation of a growing knowledge gap between the underlying technology and state-of-the-art electronic device modeling and simulations. This book bridges the gap by presenting cutting-edge research in the computational analysis and mathematical modeling of graphene nanostructures as well as the recent progress on graphene transistors for nanoscale circuits. It inspires and educates fellow circuit designers and students in the field of emerging low-power and high-performance circuit designs based on graphene. While most of the books focus on the synthesis, fabrication, and characterization of graphene, this book shines a light on graphene models and their circuit simulations and applications in photonics. It will serve as a textbook for graduate-level courses in nanoscale electronics and photonics design and appeal to anyone involved in electrical engineering, applied physics, materials science, or nanotechnology research.

Book Description
During the last decade, there has been a great deal of interest in TFETs. To the best authors’ knowledge, no book on TFETs currently exists. The proposed book provides readers with fundamental understanding of the TFETs. It explains the interesting characteristics of the TFETs, pointing to their strengths and weaknesses, and describes the novel techniques that can be employed to overcome these weaknesses and improve their characteristics. Different tradeoffs that can be made in designing TFETs have also been highlighted. Further, the book provides simulation example files of TFETs that could be run using a commercial device simulator.

Book Description
While theories based on classical physics have been very successful in helping experimentalists design microelectronic devices, new approaches based on quantum mechanics are required to accurately model nanoscale transistors and to predict their characteristics even before they are fabricated. Advanced Nanoelectronics provides research information on advanced nanoelectronics concepts, with a focus on modeling and simulation. Featuring contributions by researchers actively engaged in nanoelectronics research, it develops and applies analytical formulations to investigate nanoscale devices. The book begins by introducing the basic ideas related to quantum theory that are needed to better understand nanoscale structures found in nanoelectronics, including graphenes, carbon nanotubes, and quantum wells, dots, and wires. It goes on to highlight some of the key concepts required to understand nanotransistors. These concepts are then applied to the carbon nanotube field effect transistor (CNTFET). Several chapters cover graphene, an unzipped form of CNT that is the recently discovered allotrope of carbon that has gained a tremendous amount of scientific and technological interest. The book discusses the development of the graphene nanoribbon field effect transistor (GNRFET) and its use as a possible replacement to overcome the CNT chirality challenge. It also examines silicon nanowire (SiNW) as a new candidate for achieving the downscaling of devices. The text describes the modeling and fabrication of SiNW, including a new top-down fabrication technique. Strained technology, which changes the properties of device materials rather than changing the device geometry, is also discussed. The book ends with a look at the technical and economic challenges that face the commercialization of nanoelectronics and what universities, industries, and government can do to lower the barriers. A useful resource for professionals, researchers, and scientists, this work brings together state-of-the-art technical and scientific information on important topics in advanced nanoelectronics.
