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.
Equation: ln(I_D,FNT / V_D^2) = ln(A_eff q^3 m_0 / (8 pi h phi_B d^2 m*)) - (8 pi sqrt(2 m*) phi_B^(3/2) d) / (3 h q V_D).

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.
