1) This element is a grayish-white, lustrous, brittle metalloid. Although germanium is a poor conductor of electricity, it is often doped with other elements and is used as a transistor element in thousands of electronic applications.
2) Germanium is most important as a semiconductor material and it is in this area that the majority of germanium is used.

1) Improving strength and rollability of alloys, transistors and semiconductors.
2) "Using germanium instead of silicon as transistor material would enable faster chips containing smaller transistors because higher switching speeds than in silicon could be achieved using germanium."
3) The EU identified Germanium metal as a critical supply raw material for its member countries in 2010.
