In order to study the ''fractional Hall effect model'' of the carrier
state of high temperature superconductors, we measured the x dependenc
e of the capacitance C-t of multilayer structure Pd/La2-xSrxCuO4/(100)
SrTiO3/Pd. A strong correspondence is found between the x-C-t relation
ship and the filling factor nu dependence of the system energy in the
fractional quantum Hall effect. (C) 1997 Elsevier Science B.V.
