Notes:
CuTe thin films are synthesized onto glass substrates by scanning an Ar+ laser beam on vacuum deposited sandwich films of Cu and Te in 1:1 stoichiometric ratio. At a laser power greater than the threshold power for synthesis to occur, laser irradiation results in large synthesized areas (1 cm2) whose optical properties are demonstrated to be highly anisotropic, like CuTe, which is known to be birefringent and pleiochroic. It is demonstrated experimentally that the optical anisotropy of these laser-synthesized CuTe films depends on the wavelength, power, and polarization of the laser beam. The synthesized blade-like crystallites are preferentially oriented. It is argued that their preferential orientation is due to a combination of the high-energy gradient and the relative orientation of the laser beam polarization with respect to the scanning direction.
