...Cavendish Laboratory at England's Cambridge University, provided the theoretical underpinnings of modern solid-state physics in the 1920s. His later work with amorphous materials led to development of the "Mott model," a theoretical framework for understanding the properties of semiconductors made from amorphous materials such as sulfur, selenium and tellurium, all of which are far more economical to produce than crystalline components...
