  Recently, Patel et.al introduced a higher dimensional version of the SYK
model with random coupling in Yukawa interaction to find the linear-$T$
resistivity. We test the universality of the mechanism by replacing the scalar
with vector field in various dimensions. We find that it works for vector as
well as scalar interaction, although the details are very different. However,
this mechanism for the linear-$T$ resistivity works only in $(2+1)$ dimension
not in higher dimension independent of the interaction type. Based on these
results, we explore the role of spatial random disorder and find a simple
understanding how such random scattering converts the Fermi liquid to the
strange metal by changing the behavior of the self-energies of involved boson
and fermion.
