The binding energy for charged excitons (X(-) and X(+)) is calculated within the single-band effective mass approximation including effects due to strain for rectangular, triangular, and V-shaped quantum wires. Both X(-) and X(+) are found to be bound in rectangular InAs/InP quantum wires and V-shaped GaAs/Al(0.32)Ga(0.68)As quantum wires. We found an appreciable dependence of the trion binding energy on the size and shape of the quantum wire. We compare with available experimental data.
