We study electrical properties of 2D semiconductors as well as limits to their performance in nanoelectronic devices. After our demonstration of a single-layer MoS2 transistor, we have realized first logic operations, integrated circuits and neural networks. The mobility of MoS2 is sufficiently high to allow transistor operation well in the GHz range while the material is sufficiently mature to allow wafer-scale circuit fabrication.
