Semiconductor nanocrystals (NCs) attract substantial interest due to their
size-tunable optical and electronic properties, which allow one to consider
them as artificial atoms. These “atoms” are building blocks of new solid
materials, whose properties depend on the nature of NCs as well as how NCs are
assembled in bulk. For many applications, electrical conductivity is among the
most important characteristics of NC solids.  In the past decade, the mobility
of electronic transport in NC solids has risen by more than 5 orders of
magnitude. This improvement has been reached by decreasing distances between
NCs, narrowing the dispersion of NC sizes, changing the NCs capping material,
and by electrical doping. Finally, NC solids have been used to realize solar
cells, photodetectors, light emitting devices, transistors, and
microcircuitry.
