This is the most complicated nano 2D chip invented. It has got 100+ transistors, 3 atom thick, a layer of molybdenum, covered by sulphur atoms on 2 sides. Basically sandwiched between sulphur atoms. Atomic level chip. It is great that we are talking about how a chip is done in atomic level, 3 atoms thickness and what not. It is really fascinating how the technology is growing. Electronic students can make their research in this field for their projects and what not.
