Popis: D 2 + molecular ion in a semiconductor quantum well under laser-field radiation by using finite elements method within the effective mass approximation is theoretically studied. The effects of the laser radiation, donor-donor separation, and quantum well width on the D 2 + total energy and the D 2 + binding energy corresponding to the second ionization process D 2 + → D + + D + + e - are analyzed. We show that the laser-field radiation modifies significantly the equilibrium length and the dissociation energy of a D 2 + - complex in a quantum well. Our results in the limit cases are in good agreement with those previously reported for a single donor impurity D 0 .
