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
