A simple variational calculation of the trion triplet state energy is presented. In zero magnetic field, the triplet state of the hole trion (X + ) in two dimensions appears to be bound in a considerable mass ratio range close to the H 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.
