2D Layer Transistor Materials

[infinitexh]

Hi all,

Just got back from Berkeley today and saw some extremely exciting stuff on the materials/device side of things so I figured that I'd jump on the final rush for participation points ;)

While we learned in class (and I'm sure many of you via reading/research) graphene by itself if not quite a viable material for electronic devices; there has been a major recent push by various institution for the investigation of 2D of other Transition Metal Dichalcogenides materials (TMDC). The following is a primer for those of you unfamiliar with the field - a solid paper that also gives a very good background on this topic up until the relatively recent future (by no mean the first) that used MoS2 as a single layer channel material for transistor design:

As one can see however, MoS2 is a single member of the large and extensive family of 2D TMDC materials, and of the more recent future, many impressive works have made this kind of paradigm a possibly viable future generation transistor material past III-V's such as 

a) Finding other TMDC materials as viable channel materials

b) Using MoS2 transistors to make basic logic gates and circuits that exhibit reliable and good behavior:

There are many alternative vision of the future (be it spintronics, memory storage via DNAs etc) but I personally feel that between the III-Vs (which one can argue is in it's stage transitioning between research to industry) and the far future spintronics/nanomagnetic/quantum spinhall/topological insulator etc etc paradigms for circuit design, 2D materials ranks very high as an immediate generation that follows the III-V's; as not only are the devices CMOS compatible; their extremely small size (single layer ~ 7 A) will allow substantially extend Moore's law into the far future, with many many other benefits which only some are clearly understood at the moment.
