  This thesis is dedicated to the synthesis, characterization and the study of
electrical transport through metal nanowires and nanotubes. The metal
nanowires(Ni, Cu) and nanotubes(Cu) are synthesised by electrochemical
deposition in nanoporous templates. In the synthesis front, electrochemical
deposition schemes were developed to achieve single crystallinity and synthesis
of tubular nanostructures. The nanostructures are characterized using
structural characterization techniques such as X-ray diffraction, Scanning
electron microscopy and Transmission electron microscopy. The magnetic
nanowires are also characterized using VSM and SQUID magnetometers. The
electrical transport measurements performed in a wide range of temperature
(3K-700K) to understand the interactions of electrons with phonon, magnon and
surface when the electron mean free path is limited by the dimension of these
nanostructures. The measurements were performed in the wide range of
temperature to encompass and study the ferromagnetic to paramagnetic phase
transition in case of magnetic nanowires. We observed systematic scaling of
these interactions and the characteristic temperatures such as the Debye
temperature(\theta_R) and Curie temperature(T_C) as a function of diameter. We
also observed how these interactions change as we move from nanowires to
nanotubes of metals.
