$begingroup$ And to complicate all this, there's a thing called a "Fermi level" (of which I cannot remember all the details) that bends the bandgap of the semiconductor where it's in contact with the metal; this changes the behavior at the interface in complicated ways, up to and including making the junction rectifying (as with a Shottky diode). So you …

Usually, the semimetals or metalloids are listed as boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. Some scientists also consider tennessine and oganesson to be metalloids. Metalloids are used to make semiconductors, ceramics, polymers, and batteries. Metalloids tend to be shiny, brittle solids that act as …

This is largely because n-type Si is exempt from boron-oxygen defects and the associated light-induced degradation, is more tolerant of most metal impurities, and thus usually presents a higher minority carrier lifetime than p-type. 133, 134 In cell structures that rely on lateral transport of majority carriers, n-type silicon also offers ...
