Reduced Mass of Exciton Solution

STEP 0: Pre-Calculation Summary

Formula Used

Reduced Mass of Exciton = ([Mass-e]*(Effective Mass of Electron*Effective Mass of Hole))/(Effective Mass of Electron+Effective Mass of Hole)
μ_ex = ([Mass-e]*(m_e*m_h))/(m_e+m_h)
This formula uses 1 Constants, 3 Variables

Constants Used

[Mass-e] - Mass of electron Value Taken As 9.10938356E-31

Variables Used

Reduced Mass of Exciton - (Measured in Kilogram) - Reduced Mass of Exciton is the reduced mass of an electron and a hole that are attracted to each other by the Coulomb force which can form a bound state called exciton.
Effective Mass of Electron - Effective Mass of Electron is usually stated as a factor multiplying the rest mass of an electron.
Effective Mass of Hole - Effective Mass of Hole is the mass that it seems to have when responding to forces.

STEP 1: Convert Input(s) to Base Unit

Effective Mass of Electron: 0.21 --> No Conversion Required
Effective Mass of Hole: 0.81 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

μ_ex = ([Mass-e]*(m_e*m_h))/(m_e+m_h) --> ([Mass-e]*(0.21*0.81))/(0.21+0.81)

Evaluating ... ...

μ_ex = 1.51912367015294E-31

STEP 3: Convert Result to Output's Unit

1.51912367015294E-31 Kilogram -->0.16676459334417 Electron Mass (Rest) (Check conversion here)

FINAL ANSWER

0.16676459334417 ≈ 0.166765 Electron Mass (Rest) <-- Reduced Mass of Exciton
