Abstract

Professor Fritzsche’s research, encompassing more than three decades of beautiful experimental work combined with elegant and incisive writing, has centred primarily around two major themes; one old, one (perhaps) new, but both interwoven. The first is his interest and involvement in the study of the Metal-Semiconductor Transition; the second concerns the structural and electronic properties of disordered materials. In this dedication, we outline a further subtlety (or complexity) into these major problems in condensed matter chemistry and physics; namely the possible nature of the composition induced transition from Superconductor to Semiconductor in a system with obvious crystalline order — in association with equally obvious electronic disorder. As far as we are aware Professor Fritzsche has not, so far, ventured into the area of Superconductor-Semiconductor Transitions. We offer the present meagre contribution in the hope of 1 pressing his considerable talents into the study of yet another class 2 of remarkable transmutations!
