✦ Synopsis

Subject classification: 71.35.-y; 73.21.Fg A simple variational calculation of the trion triplet state energy is presented. In zero magnetic field, the triplet state of the hole trion (X þ ) in two dimensions appears to be bound in a considerable mass ratio range close to the H þ 2 -like trion. The critical value of electron-to-hole mass ratio estimated by various methods is found to be between 0.35 and 0.39. The energy behavior near the critical mass ratio is analytically examined.
