Semiconductor Wse2 Exciton Energy Calculator
Budget independently measured WSe2 quasiparticle/binding energies against actual optical exciton peak; not hydrogenic binding energy or gap lookup.
Description
An optical exciton transition is modeled here by subtracting a matched binding energy from a quasiparticle gap.
An optical exciton transition is modeled here by subtracting a matched binding energy from a quasiparticle gap.1
Comparing with an observed WSe₂ peak preserves the signed spectral mismatch.
When to use Semiconductor Wse2 Exciton Energy Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
How to use Semiconductor Wse2 Exciton Energy Calculator and understand its results
- Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
- Enter callerWse2QuasiparticleGapEv, callerMatchedWse2ExcitonBindingEv, observedWse2ExcitonPeakEv, following the field table and rules below, then run the tool.
- Read modeledWse2ExcitonTransitionEv, signedExcitonPeakDifferenceEv. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerWse2QuasiparticleGapEv | Caller wse2 quasiparticle gap ev | number | Required |
| callerMatchedWse2ExcitonBindingEv | Caller matched wse2 exciton binding ev | number | Required |
| observedWse2ExcitonPeakEv | Observed wse2 exciton peak ev | number | Required |
Use positive gap, nonnegative binding, and nonnegative observed peak in electronvolts. Binding must be strictly below gap. Return gap minus binding and observed peak minus that transition.
transition=gap−binding; discrepancy=observedPeak−transition Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| modeledWse2ExcitonTransitionEv | Modeled wse2 exciton transition ev | number |
| signedExcitonPeakDifferenceEv | Signed exciton peak difference ev | number |

}Limitations and assumptions
Matched measurement branch, material state, calibration, and conventions must be independently established. Results do not certify device performance or operating conditions.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected.
Alternative or Complementary methods
For a related review, use Semiconductor Quantum Dot Absorption Peak Calculator: An absorption spectral peak can be located directly in a measured quantum-dot spectrum. Retaining tied energy positions avoids forcing one peak when sampled maxima are equal. For a complementary step, use Semiconductor Quantum Well Absorption Coefficient Calculator: A single-pass absorption estimate needs the transmitted fraction after accounting for entry reflection. That optical branch must be established before taking a logarithm.
