Description

Compute the silicon resistivity of uniformly doped material from majority-carrier mobility at 300 K. Assumes low-field Caughey-Thomas mobility and complete ionization.

Resistivity From Doping Calculator is a focused tool for the following task. Compute the silicon resistivity of uniformly doped material from majority-carrier mobility at 300 K. Assumes low-field Caughey-Thomas mobility and complete ionization. It reports Resistivity from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.

When to use Resistivity From Doping

Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.

Carrier type
Required string. Majority carrier type.
Doping (cm^-3)
Required number in cm^-3. Majority dopant concentration. Must be greater than 0 cm^-3.

How Resistivity From Doping works

Compute the silicon resistivity of uniformly doped material from majority-carrier mobility at 300 K. Assumes low-field Caughey-Thomas mobility and complete ionization. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Resistivity (Ω·cm)
Returned number in Ω·cm. Material resistivity.

Limitations and assumptions

  • Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
  • Doping must be at least 5e-324.
  • Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Alternative or Complementary approaches

Compare the estimate with measured process data, current device documentation, and a higher-fidelity circuit, field, thermal, quantum, or TCAD model when the decision requires it.
