In any scenario of the electroweak baryogenesis, the profile of the CPviolating bubble wall, created at the first-order phase transition, plays anessential role. We attempt to determine it by solving the equations of motionfor the scalars in the two-Higgs-doublet model at the transition temperature.According to the parameters in the potential, we found three solutions. Two ofthem smoothly connect the CP-violating broken phase and the symmetric phase,while the other connects CP-conserving vacua but violates CP in theintermediate region. We also estimate the chiral charge flux, which will beturned into the baryon density in the symmetric phase by the sphaleron process.Comment: 22 pages, latex, 6 figures (included
