Abstract
Electron-here systems on a Haldane sphere are studied by exact numerical di agonalization. Low-lying states contain one or more types of bound charged excitonic complexes X-k(-), interacting through appropriate pseudo potentia ls. Incompressible ground states of such multicomponent plasmas are found. A generalized multicomponent Laughlin wave function and composite fermion p icture are shown to predict the low-lying states of an electron-hole gas at any value of the magnetic field.
