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

Sheet Carriers Per Square Meter (m⁻²)

Required number in m⁻².

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

Two-dimensional HEMT electron-sheet charge magnitude from measured sheet carrier number density. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Charge Coulombs Per Square Meter (C/m²)

Returned number in C/m².

• Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
• Sheet Carriers Per Square Meter must be at least 0.
• 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.

• GaN HEMT 2DEG Mobility Calculator

  Calculate GaN HEMT two-dimensional electron-gas mobility from measured sheet density and sheet resistance.

• 2DEG Density Calculator

  Estimate two-dimensional electron gas sheet density with a parallel-plate capacitor model that treats the band offset as the voltage dropped across the spacer.

• N-Type Carrier Concentration Calculator

  Solve the n-type charge-neutrality relation n = (ND + sqrt(ND² + 4·ni²))/2 for equilibrium electron concentration. ND is ionized donor concentration in cm⁻³ and ni is intrinsic concentration in cm⁻³, both per volume.
