Transmission Coefficient Calculator

How to Use the Calculator

1. Enter the barrier height (V₀) in electron volts (eV).
2. Enter the barrier width (a) in nanometers (nm).
3. Click the "Calculate" button to compute the transmission coefficient.
4. The result will be displayed along with the formula used.

Working Principle

The transmission coefficient (T) is a measure of the probability that a particle will pass through a potential barrier. It is given by the formula:

T = exp(-2 * sqrt(2m(V₀ - E)/ħ²) * a)

Where:

• m is the mass of the particle.
• V₀ is the height of the potential barrier.
• E is the energy of the particle.
• ħ is the reduced Planck constant.
• a is the width of the potential barrier.

This calculator assumes the energy of the particle (E) to be zero for simplicity.
