Abstract
Second-harmonic generation in the layered semiconductor GaS excited wi th the wavelength lambda = 1579 nm is investigated with the Maker frin ge technique. It is shown that the second-harmonic signal originates f rom domains in the crystal, which consist of the noncentrosymmetric C- 5(3 upsilon) polytype. The results are in good agreement with X-ray di ffraction data. (C) 1997 Elsevier Science Ltd.
