Van der Waals metal contacts could be the key to CMOS made from thin-film 2D semiconductors, according to the Korea Institute of Science and Technology (KIST), which has made contacts from chlorine-doped tin diselenide. “It was difficult to implement complementary logic circuits with conventional two-dimensional semiconductor devices because they only exhibit the characteristics of either n-type ...
