Amorphous Oxide Semiconductors - Igzo and Related Materials for Display and Memory

AMORPHOUS OXIDE SEMICONDUCTORS
 
A singular resource on amorphous oxide semiconductors edited by a world-recognized pioneer in the field
 
In Amorphous Oxide Semiconductors: IGZO and Related Materials for Display and Memory, the Editors deliver a comprehensive account of the current status of--and latest developments in--transparent oxide semiconductor technology. With contributions from leading international researchers and exponents in the field, this edited volume covers physical fundamentals, thin-film transistor applications, processing, circuits and device simulation, display and memory applications, and new materials relevant to amorphous oxide semiconductors.
 
The book makes extensive use of structural diagrams of materials, energy level and energy band diagrams, device structure illustrations, and graphs of device transfer characteristics, photographs and micrographs to help illustrate the concepts discussed within. It also includes:
* A thorough introduction to amorphous oxide semiconductors, including discussions of commercial demand, common challenges faced during their manufacture, and materials design
* Comprehensive explorations of the electronic structure of amorphous oxide semiconductors, structural randomness, doping limits, and defects
* Practical discussions of amorphous oxide semiconductor processing, including oxide materials and interfaces for application and solution-process metal oxide semiconductors for flexible electronics
* In-depth examinations of thin film transistors (TFTs), including the trade-off relationship between mobility and reliability in oxide TFTs
 
Perfect for practicing scientists, engineers, and device technologists working with transparent semiconductor systems, Amorphous Oxide Semiconductors: IGZO and Related Materials for Display and Memory will also earn a place in the libraries of students studying oxides and other non-classical and innovative semiconductor devices.
