Abstract We study the effects of electron--phonon interaction on the electron ground state in a symmetric triangular quantum well, and calculate the ground state energy of an electron in the GaAs/Al0.96Ga0.04As triangular quantum well including the effects of the interaction between electrons and confined LO phonons by using a modified Lee--Low--Pines variational method. The electron wavefunction in the triangular well is chosen as the Airy function. The numerical results are given and discussed.
