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

Magnetic field (T)

Required number in T. Applied static magnetic field.

g factor

Optional number. Electron g factor of the qubit material.

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

Compute the Zeeman energy splitting of a spin qubit from its g factor and the applied magnetic field. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Zeeman splitting (ueV)

Returned number in ueV. Energy splitting between spin states.

• Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
• 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.
