  The conventional baryogenesis mechanism is based on the one Higgs doublet
within the standard model, at the electroweak scale $T\sim 100 GeV$. In this
model the strong first order phase transition due to the spontaneous symmetry
breaking imposes the folowing condition on the mass of the Higgs field:
$m_H\lesssim 40 GeV$, which is contrary to the recently observed value
$m_H\simeq 126 GeV$. In this paper we propose a baryogenesis mechanism within a
two-Higgs-doublet model in which the phase transition occurs in one stage. This
model is consistent with the observed mass of the Higgs. We obtain the true
vacuum bubble wall velocity and thickness in this model. Then, we use nonlocal
baryogenesis mechanism in which the interaction of fermions with the boundary
of the expanding bubbles leads to CP violation and sphaleron mediated
baryogenesis.
