The binding energies of the lowest singlet and triplet states of positively charged excitons confined to a quantum disc are studied using exact diagonalization techniques. We investigate the dependence of the binding energies on the confinement strength and on the effective electron-to-hole mass ratio. The results we have obtained show that the binding energies are closely correlated to the strength of the confinement potential and the effective electron-to-hole mass ratio.
