Charged pattern formation on the surfaces of self-assembled cylindrical micelles formed from oppositely charged heterogeneous molecules such as cationic and anionic peptide amphiphiles is investigated. The net incompatibility χ among different components results in the formation of segregated domains, whose growth is inhibited by electrostatics. The transition to striped phases proceeds through an intermediate structure governed by fluctuations, followed by states with various lamellar orientations, which depend on cylinder radius Rc and χ. We analyze the specific heat, susceptibility S (q*), domain size Λ=2π/ q*, and morphology as a function of Rc and χ.
