Monolayer Semiconductors: Electron Field Emission of Geometrically Modulated Monolayer Semiconductors (Adv. Funct. Mater. 7/2018)

Recently, engineering of 2D semiconductors has been widely highlighted for diverse potential applications. In article number 1706113, Yi-Hsien Lee and co-workers report highly efficient and stable electron emission of monolayer semiconductors in low turn-on electric fields. Geometrical control by integrating 1D nanostructure arrays for geometrical modulation is key to this achievement.
