Abstract
We have studied the variation of the pseudogap through resistivity and ther
mopower measurements over a wide range of carrier concentration in Bi-, Tl-
and Hg-based high-T-c. systems. In all the three system the signature of a
gap in the normal state excitation spectrum has been observed. The gap ope
ning temperature (T*) is found to follow a common emperical relation of the
form T*=c/p(n) with different c and n values. (C) 2001 Elsevier Science B.
