1. Carrier Concentration

Consider a germanium sample at T = 300°K with doping concentration of N d = 0 and N a = 1016 cm-3. Assume complete ionization and electron and hole mobilities are 3900 cm2/V⋅sec and 1900 cm2/V⋅sec. The applied electric field is E = 50 V/cm. - Solution Since N a > N d, the semiconductor is p-type and the majority carrier hole concentration,

Germane - Wikipedia

Germane is the chemical compound with the formula Ge H 4, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium. Like the related compounds silane and methane, germane is tetrahedral. It burns in air to produce GeO 2 and water. Germane is a group 14 hydride .
