• Evaluate a fitted field-exponential band-to-band tunneling current magnitude from electric field and two empirical coefficients.
• Compare fabrication or device scenarios while holding coefficients and unit conventions constant.
• Check a hand calculation before moving to a higher-fidelity process, circuit, or TCAD model.

E0 controls exponential suppression while A fixes both scale and the declared nA output units.

• This is a compact empirical current law, not a full Kane current-density model; device area, band structure, barrier shape, and trap-assisted tunneling are omitted.
• Use parameters measured for the same material, geometry, temperature, and operating regime whenever the result informs engineering work.

• WKB Tunneling Probability

  Use WKB Tunneling Probability to compute the approximate quantum tunneling probability through a rectangular barrier with the WKB expression exp(-1.025 times width in angstroms times the square root of height in eV). Choose this tool when you need to evaluate a fitted field-exponential band-to-band tunneling current magnitude from electric field and two empirical coefficients.

• Gate Tunneling Current

  Use Gate Tunneling Current to estimate gate-oxide tunneling leakage per unit area from oxide thickness and an exponential attenuation. Choose this tool when you need to evaluate a fitted field-exponential band-to-band tunneling current magnitude from electric field and two empirical coefficients.
