WebApr 17, 2024 · Both elements are brittle and have a metallic luster. Each of these elements has an outer electron shell that contains four electrons; this property of silicon and germanium makes it difficult for either element in its purest form to be a good electrical conductor. One way to cause a metalloid to conduct electric current freely is to heat it up. WebThe most used semiconductor materials are silicon, germanium, and gallium arsenide. Of the three, germanium was one of the earliest semiconductor materials used. Germanium has four valence electrons, which are electrons located on the outer shell of the atom. The number of valence electrons in a semiconductor material determines its conductivity.
