Abstract:
In this work, theoretical investigation on the superconductivity of Antimony under
~ pressure has been made. Experimental and theoretical values of pressure dependent
parameters like, electron-phonon coupling constant(A), average phonon frequency ((w) )
and the corrosponding Debye temperature(8 D) are used to calculate superconducting
transition
temperature(T
c
)
of the rhombohedral(A7), trigonal approximant(TA) and
BCC phases of Antimony using
the modified McMillan transition temperature equa-
tion.
The calculated superconducting transition temperature(T
c
)
shows a character-
istic dependence on pressure.
At the phase transition from A7 to TA, a considerable
increase in
T
c
is observed with increasing pressure. A large jump in T
transition pressure from TA to BCC and reaches its turning point at T ~ 9.79K.
