Hole Effective Mass Calculator
Combine heavy- and light-hole masses into a density-of-states hole mass.
Description
Combine heavy- and light-hole masses into a density-of-states hole mass.
Hole Effective Mass Calculator is a focused tool for the following task. Combine heavy- and light-hole masses into a density-of-states hole mass. It reports mdos*/m0 from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Hole Effective Mass
Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.
- mhh*/m0
- Optional number. Heavy-hole effective mass ratio mhh*/m0.
- mlh*/m0
- Optional number. Light-hole effective mass ratio mlh*/m0; defaults to the heavy value.

How Hole Effective Mass works
Combine heavy- and light-hole masses into a density-of-states hole mass. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- mdos*/m0
- Returned number. Density-of-states hole mass ratio mdos*/m0.
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.
