Abstract
AbstractA phase diagram for variable hole to electron mass ratio of two‐component Coulomb crystals is presented as result of the first‐principle computer simulations. A critical mass ratio for the existence of quantum Coulomb crystals is of the order of 80 in three dimensions. At very low temperature the electron–hole system with decreasing hole mass can form antiferromagnetic crystal structure composed by two perfect hole lattices each consisting of the holes with the same spin projections.
