Hole-hole interaction in a strained In$_x$Ga$_{1-x}$As two dimensional system

/ Abstract
The interaction correction to the conductivity of 2D hole gas in strained GaAs/In x Ga 1 − x As/GaAs quantum well structures was studied. It is shown that the Zeeman splitting, spin relaxation and ballistic contribution should be taking into account for reliable determination of the Fermi-liquid constant F σ 0 . The proper consideration of these effects allows us to describe both th temperature and magnetic field dependences of the conductivity and find the value of F σ 0 .
