Resumen:
Tunneling spectroscopy played a central role in the experimental
verification of the microscopic theory of superconductivity
in the classical superconductors. In the case of
high-temperature superconductors (HTS), the initial attempts to adopt
the
same approach were hampered by various problems related to
the complexity of these materials. The progresses made in synthesizing
high quality samples, and the use of scanning tunneling
microscopy/spectroscopy (STM/STS) on these compounds allowed to overcome
the main difficulties. In this review, we present some of
the experimental highlights obtained with STM/STS techniques over
the last decade. Most of the results confirm the fact that
this new class of materials differ noticeably from the conventional
BCS superconductors, and provide convincing arguments toward
the understanding of the microscopic mechanisms at the origin
of high-temperature superconductivity.
