Fabrication of single-crystal semiconductor optical waveguides by solid-state diffusion
(1972)
Optical surface waveguides have been fabricated by diffusing selenium into single-crystal CdS substrates to produce graded-composition CdS Se crystals. Planar guides which confine a beam in one dimension and guides produced ...
Fluorescence of graded-band-gap CdSxSe1-x crystals produced by diffusion
(1972)
The fluorescence of CdSxSe1-x mixed crystals with band-gap gradients as large as 1200 eV/cm has been investigated at 77°K. The graded samples were produced by heating CdSe or CdSxSe1-x platelets in a sulfur-selenium ...
