Abstract
We have studied the influence of an in-plane (001) strain on the energ y position of the long wavelength optical modes of CaAs1-xPx alloys, T hese alloys have a two mode behavior. We have observed that the strain -induced shift of the Raman peaks corresponding to the GaAs-like vibra tion is greater than that of the GaP-like vibration. This result shows that the two modes are not affected in the same way by the strain. (C ) 1996 American Institute of Physics.
