Charge Density Waves in the Electron–Hole Liquid in Coupled Quantum Wells

  • V. S. Babichenko
  • I. Ya. Polishchuk


A many-component electron–hole plasma is considered in coupled quantum wells. The electrons and the holes are localized in the different wells. It is found in our previous works that the electron–hole liquid is the ground state of the system. In this paper it is shown that, as the separation between the wells increases, static charge density waves arise resulting in charge fluctuations which form a honeycomb lattice.
