We shall present an approach to determine important properties of the superconducting condensate using the methods of single-electron tunneling (SET). Placing an island of an HTS material in a SET device allows to study the very complicated system by fine-tuning the number of electrons in it.
We have fabricated a Coulomb blockade electrometer consisting of an ultrasmall YBa2Cu3O7-
