Electron ionization rate α i vs. 1/F. Consequently, electrons are the majority charge carriers of the material. Silicon Carbide, sometimes mistakenly referred to by the trade name Carborundum, is used due to its properties of high hardness (Mohs hardness > 9), wear resistance, its chemical inertness, high thermal conductivity, abrasion resistance, low coefficient of thermal expansion, thermal shock resistance, and strength at high temperature ranges. What is silicon's electrical conductivity? T = 300 K. (Maes et al. T = 300 K. (Grant ). Normalized breakdown voltage vs. temperature for an abrupt p-n junction at different doping levels. T = 300 K. . (Crowell and Sze ) The term intrinsic means that electrical conductivity is an inherent property of the semiconducting material and independent of the presence of additives. The intrinsic carrier concentration is:where is the effective density of states (), is the energy gap (eV), is Boltzmann's constant (eV/K), is temperature (K), and is the effective density of states at 300 K.. Conductivity Type An n-type (negative-type) extrinsic silicon semiconductor is a semiconducting material that was produced by doping silicon with an n-type element of Group V A, such as P, As, or Sb. Pure silicon and other elemental semiconductors are commonly referred to as intrinsic semiconductors. Breakdown voltage and breakdown field vs. doping density for an abrupt p-n junction. Details. Hole ionization rate β i vs. 1/F. This depends on a few parameters of which the purity and the temperature have a significant influence. ).
