For a good fifty years, germanium was little more than a box on the periodic table. It really wasn't good for anything. It was only with the development of electronics that germanium's value as a very ...

Silicon is a semiconductor in group IVA of the periodic table with atomic number 14, an atomic weight of 28.086, and a density of 2.33 Mg/m 3. It melts at 1410 C. The electronic configuration of the ...

Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table—the "silicon group.
