    • Influences of Ga Doping on Crystal Structure and Polarimetric Pattern of SHG in ZnO Nanofilms 

      Long, Hua; Habeeb, Ammar A.; Kinyua, Dickson M.; Wang, Kai; Wang, Bing; Lu, Peixiang (Nanomaterials, 2019-06-21)
      The second-harmonic generation (SHG) in gallium doped ZnO (GZO) nanofilms was studied. The Ga doping in GZO nanofilms influenced the crystal structure of the films, which affected SHG characteristics of the nanofilms. ...

    • Interferometry Analysis of Cellophane Birefringence 

      Kinyua, Dickson M.; Rurimo, Geoffrey K.; Karim, Patrick M.; Maina, Stephen N.; Ominde, Calvin F. (Optics and Photonics Journal, 2013-10)
      This paper reports on a simple approach of determining the ability of a transparent material, such as cellophane to rotate the direction of polarization of a light beam. In order to determine the birefringence of such a ...
