  The cuprates seem to exhibit statistics, dimensionality and phase transitions
in novel ways. The nature of excitations [i.e. quasiparticle or collective],
spin-charge separation, stripes [static and dynamics], inhomogeneities,
psuedogap, effect of impurity dopings [e.g. Zn, Ni] and any other phenomenon in
these materials must be consistently understood. In this note we suggest Single
Electron Tunneling Transistor [SET] based experiments to understand the role of
charge dynamics in these systems. Assuming that SET operates as an efficient
charge detection system we can expect to understand the underlying physics of
charge transport and charge fluctuations in these materials for a range of
doping.
  Experiments such as these can be classed in a general sense as mesoscopic and
nano characterization of cuprates and related materials.
