Abstract
The surface morphology of PrBa2Cu3O7-x (PBCO) single crystals was investiga
ted using scanning tunneling microscopy and atomic force microscopy. We wer
e able to estimate the width of the semiconducting gap and the variations o
f the local density of stares (LDOS) near the Fermi level (E-F) of single c
rystals at room temperature on the basis of spectroscopic measurements of t
he local I-V characteristics. The characteristic feature of reduced PBCO si
ngle crystals in the normal state are also discussed. (C) 1999 Elsevier Sci
