ScholarBank@NUS Repository. https://doi.org/10.1063/1.3155428 | Abstract: | Excitation photon energy and carrier density dependence of spin dynamics in bulk CdTe crystal was studied by time resolved pump-probe reflectivity technique at room temperature. The results show that spin relaxation time decreases monotonously. While with increasing excitation carrier density, the time constants increases initially then decreases after reaching a maximum value. Our experimental results reveal that both D'yakonov-Perel' [M. I. D'yakonov and V. I. Perel', Sov. Phys. JETP 38, 177 (1974)] and Elliot-Yafet [R. J. Elliott, Phys. Rev. 96, 266 (1954); Y. Yafet, Solid State Phys. 14, 1 (1963)] mechanisms dominate the spin relaxation process in CdTe crystal. © 2009 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/97542 | ISSN: | 00036951 | DOI: | 10.1063/1.3155428 |
