Variable Band Gap Emitters and Detectors.

Abstract

The objective of the present work has been the growth and characterization of zero band gap semiconductors. Significant advances were made in the controlled and reproducible growth of low carrier concentration films of IV-VI compounds and their alloys. A hot wall method, characterized by near equilibrium conditions, was employed for the growth of PbS, PbSe, SnTe and Pb1-xSnxSe. The theoretical studies involved first-principles calculation of the electronic structure of Pb(1-x)Sn(x)Te, detailed studies of the constant energy surfaces of the IV-VI compounds, and the investigation of the effect of isotropic and uniaxial strains on the (110) subsidiary extrema in the conduction and valence bands of these materials.
