Communication: Facile fabrication of high-temperature superconducting La2CuO4 thin films through the combination of two seemingly disparate techniques is reported. Pulsed laser ablation is used to produce stoichiometric, c-axis oriented La2CuO4 thin films similar to 3700 Angstrom in thickness. The convenient method of controlled room-temperature chemical oxidation using aqueous sodium bromite is then utilized to introduce excess holes in the valance band of La2CuO4. This induces superconductivity in the otherwise antiferromagnetic semiconductor.
