SUMMARY

The discussion focuses on calculating the number densities of n-carriers in silicon at temperatures of 100 K and 250 K, given the bandgap energy (Eg) of 1.12 eV and the effective mass of n-carriers (m*) as 0.31 times the electron mass (me). The relevant equation for this calculation is the square root of (NcNv) multiplied by e^(-Eg/kt). The participants clarify whether the semiconductor is intrinsic, which is assumed in the absence of specified conditions.

PREREQUISITES
  • Understanding of semiconductor physics
  • Familiarity with the concepts of effective mass and bandgap energy
  • Knowledge of the Boltzmann constant (k) and its application in thermal energy calculations
  • Ability to manipulate exponential functions in the context of physical equations
NEXT STEPS
  • Research the calculation of carrier densities in intrinsic semiconductors
  • Learn about the temperature dependence of semiconductor properties
  • Explore the significance of effective mass in semiconductor physics
  • Study the derivation and application of the equation NcNv in semiconductor theory
USEFUL FOR

Students and professionals in materials science, electrical engineering, and physics, particularly those focusing on semiconductor device design and analysis.

Homework Statement



In silicon, Eg = 1.12 eV and the effective mass of the n-carriers is m* = 0.31me, where me is the electron mass. Find the number densities of n-carriers at 100 K and at 250 K.

Homework Equations



square root of (NcNv)*e^(-Eg/kt)



The Attempt at a Solution



The attempt is simply this equation and it isn't working. Help :)

Does it say if it is an intrinsic semiconductor or is it assumed? Also, can we see some work.
