Abstract
The theories of conventional super conductivity are
reviewed. We have investigated the electric and magnetic
properties using different
seebeck effect measurement,
experimental techniques such as
Hall effect measurement, and
standard four - probe method.
Based on the experiment, transition
carrier concentration are estimated. Our
metallic above transition temperature.
temperature and
samples behave
To explain the
superconducting mechanism, exciton mechanism is discussed with
respect to ABB (Allender, Bray and Bardeen) model: - a thin
metallic layer on a semiconductor surface. Using computer
simulation, we observe that our results agree with theoretical
proposed exciton mechanism model (ABB)
