Quantum Tunneling Calculator

Calculate the transmission coefficient for quantum tunneling through a rectangular potential barrier.

Electron mass: 9.109e-31 kg

Results

Transmission Coefficient (T): 7.1395e-4

Reflection Coefficient (R): 0.999286

Decay Constant (κ): 3.6224e+9 m⁻¹

Penetration Depth: 0.2761 nm

Formula

T = e^(-2κL)

where κ = √(2m(V₀-E))/ℏ

V₀ = barrier height, E = particle energy, L = barrier width
