F-N tunneling

  1. Dec 12, 2017 #1
    Hi, Everyone, Hope you are fine and doing great. I am new here and need to ask how can we match both sides of F-N tunneling equation in unit. I am attaching the equation, i am working on but i could not solve the unit match problem.
    if the left term has unit A/V2 then how can we solve 2nd term in the right side to have exactly same units. Please help...

    attached is the link from which i took this equation.

    The term on the left is a transcendental function, and therefore to make sense must have no units.
