Computer-Rendered Illustration of a Nanoribbon Transistor (IMAGE)
Caption
Computer-rendered illustration of a nanoribbon transistor made from molybdenum disulfide, MoS2, one of the two-dimensional semiconductors studied. The blue and yellow spheres represent molybdenum and sulfur atoms. Missing sulfur atoms and red oxygen atoms at the etched edges illustrate possible atomic-scale edge defects, a key concern when narrowing the transistor channel. Gray source and drain metal contacts connect to the channel on each side, while the purple layer underneath represents the gate structure used to control the transistor. The study shows that such atomically thin channels can be narrowed to about 25 nanometers while still retaining well-behaved transistor behavior.
