Germanium is Found Useless
Germanium was thought of as a poor conductor so it was not used that much. -
Germanium's Purpose is Realized
After 1945 germanium became economicaly important. It was realized that germanium was a great semiconductor. It gained popularity in the military for its use in diodes. The first major use for it was the point-contact Schottky diodes which was used for radar pulse detection. Before 1945 only a few hundred kilograms were produced. at the end of the 1950's the worldwide production reached to 40 metric tons. -
