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

Electron density (m^-3)

Required number in m^-3. Free electron density.

The cited overview of Semiconductor device supplies background for the terminology and domain context used by this tool.^[1]

Compute the classical plasma angular frequency and terahertz frequency of an electron gas from its density. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Plasma angular frequency (rad/s)

Returned number in rad/s. Plasma angular frequency.

Terahertz frequency (THz)

Returned number in THz. Plasma frequency in terahertz.

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

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.
