New strategy enhances 2D transistor dielectric layers

Transistors based on two-dimensional (2D) semiconductors, such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), could outperform conventional silicon-based transistors, while also being easier to reduce in size. To perform well, these transistors need to be based on high-quality dielectric materials, which can be difficult to prepare.
