| Abstract: | The interaction of Wannier excitons in ternary mixed crystals Al_xGa_(1-x)As with two branches of LO- phonons is studied.The effective Hamiltonian of Wannier exciton is given.And the operators are equivalent to those of binary crystals for x=0,x=1.In the limt of weak coupling,the ground-state energy,the binding energy and exciton radii are calculated for Al_xGa_(1-x)As with different composition x. |
