Abstract

In this paper, the design principle of fluoride-based devices for deep ultraviolet emission is presented. Variations in band structure and lattice constant of LiBa_xCa_yS_r(1-x-y)F₃ and Li_(1-x)K_xBa_(1-y)Mg_yF₃ are studied using ab initio calculations based on local density approximation. Results suggest that lattice-matched double-heterostructures of direct-band-gap compounds LiBa_xCa_ySr_(1-x-y)F₃ on LiSrF₃ and Li_(1-x)K_xBa_(1-y)Mg_yF₃ on either LiBaF₃ or KMgF₃ are sufficiently feasible to fabricate.
