Question

Since 2020, this element is the most popular dopant for silicon in PERC (“perk”) modules, since it greatly lessens light-induced degradation. Ions of this element are typically used in focused ion beams that can edit circuits. Companies like EPC and Navitas are using a wide bandgap compound containing this non-gaseous element to make cutting edge power ICs. This is the third of four elements in the name of a material that, like cadmium (-5[1])telluride, is a major kind of thin-film solar cell. (15[1])Akasaki and Amano used a sapphire substrate to grow this element’s (*) nitride, enabling the Nobel Prize-winning creation of blue LEDs. (10[2])This is the main alternative to boron as a dopant for p-type semiconductors. After silicon, the second-most popular semiconductor (-5[1])is this element’s arsenide. For 10 points, name this metal that might have uses in soft electronics since it melts at body temperature. ■END■ (10[2])
