Calculate the tunneling probability for a particle through a 1-D barrier.

Step 1: Enter Barrier Parameters

Example: Electron mass \(9.11 \times 10^{-31}\) kg

Example: 1 nm (1e-9 m)

Transmission Coefficient: $$ T \approx \exp\left(-2L\sqrt{\frac{2m\,(U-E)}{\hbar^2}}\right) $$

For \(E \ge U\), \(T \approx 1\). \(\hbar = 1.054571817 \times 10^{-34}\) J·s.
