Abstract:

The optical properties of CdSe and ZnO single crystals have been determined from reflectivity measurements in the range of photon energies 2.5 - 14 electron volts. The measurements were made in a one meter vacuum monochromator using a hydrogen emission source. The crystals were grown from the vapor phase and consisted of platelets CdSe and bulk prisms ZnO. The optical constants, n and k, and the real and imaginary parts of the dielectric constant were derived from the reflectivity measurements by a Kramers-Kronig analysis. The observed spectrum of CdSe is in good agreement with previously reported results of Cardona. The observed ZnO spectrum corressponds with similar results reported for other II-VI wurtzite semiconductors. The peaks have been interpreted as direct interband transitions in terms of an analogous zinc-blende energy band structure. Author
