Question

This is the heaviest element for which a solid trimethyl source is used to react it with group V (“vee”) materials in the MOVPE process. A lab at Oregon discovered a pigment in which this element and yttrium help expose the intense blue color of plus-3 (-5[1])manganese ions. The most common sources (15[1])for this high-demand p-block element are leaching from zinc sulfide ores and recovery after its most notable compound is etched onto glass and wafers. This is the [emphasize] (-5[1])second of four elements in the name of a flexible (-5[2])semiconductor that competes with (*) amorphous silicon and cadmium telluride for use in thin-film solar (10[2]-5[1])cells. Aluminum-doped zinc oxide is (10[1])a cheaper alternative to a (10[1]-5[1])compound containing this (-5[1])metal and (10[1])tin that is deposited to create transparent conducting (10[1])films. This metal is named for the (10[1])blue-violet line in its spectrum. For 10 points, name (10[1])this metal found in LCDs as its tin oxide. (10[2]0[4])■END■
