Scientists investigate how electric current flows in multilayer 2-D materials
(Left) In 2-D, 13-layer MoS2, the “HOT SPOT” (the center of current distribution) is located in the upper layers at a large gate bias. (Right) In 2-D, 13-layer graphene, the “HOT SPOT” is located in the lower layers at a large gate bias. The difference arises because the location of a “HOT SPOT” is due to the material’s physical properties. Credit: Das and Appenzeller. ©2013 American Chemical Society
