Abstract
Single crystals of CuGaSe2 were studied using magnetophotoluminescence in magnetic fields up to 20 T at 4.2 K. The rate of the diamagnetic shift in the A free exciton peak was determined to be 9.82× 10-6 eV/ T2. This rate was used to calculate the reduced mass as 0.115 m0, the binding energy as 12.9 meV, the Bohr radius as 5.1 nm and an effective hole mass of 0.64 m0 (m0 is the free electron mass) of the free A exciton using a low-field perturbation approach and the hydrogenic model. © 2010 American Institute of Physics.
