Two-dimensional Valleytronic Materials: From principles to device applications

Valleytronics based on 2D materials is a brand-new field which is considered as the heart of next-generation semiconductor technology. Valleytronics focuses on the generation and detection of valley-polarized currents, as well as the design and fabrication of optical devices, which achieve circularly polarized light absorption and electroluminescence. This book aims to give an overview of the recent theoretical and experimental developments achieved in valleytronics based on various 2D materials. After some experimental progress at room temperature in manipulating the valley degree of freedom, valleytronics is considered superior to spintronics in the semiconductor industry. The book provides a useful reference for the growing community of researchers in the field of valleytronics, 2D materials and semiconductors. It will ignite the readers’ interest in valleytronics and push the field forward.

Key Features:

• The first complete monograph on the newly-emerging field valleytronics. • Contains up-to-date developments in theory and experiment. • Detailed book encompassing various fields in physics to induce valley polarization. • Provides a suitable reference for researchers in the still-developing field of valleytronics. • Describes the major challenges people faces to realize the practical application of the valley degree of freedom
