Lists of Nobel Prizes and Laureates


The semiconducting material that was used in the crystal radio was often a composition of different types of elements. One example was galena, which consists of lead and sulfide.

Today, some compositions are used as semiconductors, but mostly the pure elements silicon (Si) and sometimes germanium (Ge) are being used. These semiconducting elements are located in group 14 of the periodic table.
