Coal to Replace Silicon and Graphene

New approaches to the materials world are literally flooding out of labs every day and this is but one. The "Great Acceleration" is upon us. This could change the cost structure in display, batteries, solar and many other areas. Comments welcome and wanted.

This is the monolayer molybdenum disulfide work -- interesting in that it has a direct bandgap. (Not sure what this has to do with coal?)
 
Interesting material, as mentioned by U235 it has a 1.8eV bandgap. Am I wrong if I say that the VG should be > 1.8V ?
The article says that the transistor "consume 100,000 times less energy in standby state than traditional silicon transistor"... but the active power consumption will be higher than for the Silicon (bandgap = 0.7V). As mentioned by Arthur, MOS2 would be used in solar or battery, but not really to design chips replacing the Silicon...
 
Researchers have been writing about molybdenum disulfide (MoS2) since 2011, so in 5 years the concept hasn't made the leap from research to practice yet.
 
Daniel -- I think these good pieces of research do get over-hyped when written up for a popular articles. And 5 years is a very short time.

Along the same lines: Does anyone know of a fundamental discovery/ breakthrough which made it into high-volume production in less than 10 years?

The one I know -- which took about 10 years -- was the giant magneto-resistance (GMR) effect, which was the basis of the new hard disk read-heads late 1990s - 2000 onwards.
