i give it a 45% chance this is the "homo-pedo" spammer false-flagging.

do you understand what makes silicon a semiconductor? if not, this is a difficult question to answer without an understanding of solid-state physics.
silicon atoms have four valence electrons, and they bond with 4 neighboring atoms in the silicon crystal lattice. this makes it difficult for electricity to conduct because all the outer electrons are stuck in bonds. but if you add some atoms that have 5 valence electrons (like arsenic) or 3 valence electrons (like gallium), then youve introduced either an extra electron, or an extra hole in the bonds, both of which make it easier to conduct electricity. the former is called N-type doping and the latter is called P-type doping. put an N-type next to a P-type and youve created a diode, the basis for solid-state devices.
anyway, you can see how mixing equal parts gallium and arsenic would "cancel out" this effect and make all the electrons sit in bonds again.
