Superlattice Miniband Width Calculator
Estimate the superlattice miniband width from the contact coupling and the tunneling decay across the barrier.
Description
Estimate the superlattice miniband width from the contact coupling and the tunneling decay across the barrier.
Superlattice Miniband Width Calculator is a focused tool for the following task. Estimate the superlattice miniband width from the contact coupling and the tunneling decay across the barrier. It reports Miniband width from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Superlattice Miniband Width
Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.
- Barrier width (nm)
- Required number in nm. Barrier width between adjacent wells.
- Coupling at contact (meV)
- Required number in meV. Coupling energy when the wells are in contact.
- Decay length (nm)
- Required number in nm. Evanescent decay length of the wave function in the barrier.
The cited overview of Quantum tunnelling supplies background for the terminology and domain context used by this tool.1
How Superlattice Miniband Width works
Estimate the superlattice miniband width from the contact coupling and the tunneling decay across the barrier. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Miniband width (meV)
- Returned number in meV. Nearest-neighbor tight-binding miniband width, 4|t|.
Limitations and assumptions
- 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.
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.
