Structural and optical properties of variable bandgap crystalline and amorphous semiconductors of tetrahedral coordination

A two part study of the structural and optical properties of variable bandgap crystalline and amorphous group IV semiconductors is presented here. The first covers an extensive set of experiments on the novel semiconducting material ;The r.f. sputtering technique was used to produce ;The second part of this thesis examines the structural properties of the tetrahedrally coordinated semiconductors, a-...
