The most common of these objects is elemental silicon.
When heated, adatom pair chain structures form compact islands on the surface of one of these objects. A "compound" one of these objects is a likely source of solar cells. Ion implantation is used to create extra electrons or an "electron hole" in these objects in a process called "doping," which results in the n and p types of these objects. The most common of these objects is elemental silicon. For 10 points, name these materials with intermediate conductivity, prevalent in integrated circuits.
