Researchers discover the formation of valley domain, potentially expand valleytronics technology

Researchers from Korea's Daegu Gyeongbuk Institute of Science and Technology (DGIST) discovered the formation of valley domain, which can expand valleytronics technology.

The researchers say that they have solved the stability problem inherent in valley spin in valleytronics devices by discovering the formation of valley domain in 2D molybdenum disulfide (MoS2). The team identified that a valley domain formed in an extreme nano structure can be used to store information in place of spin.
