Question:Model I-V in Python


Model I-V.

Method: Perform an integral, as a function of E, which outputs Current for each Voltage value used. This is repeated for an array of v_values. The equation can be found below.

enter image description here

Although the limits in this equation range from -inf to inf, the limits must be restricted so that (E+eV)^2-\Delta^2>0 and E^2-\Delta^2>0, to avoid poles. (\Delta_1 = \Delta_2). Therefore there are currently two integrals, with limits from -inf to -gap-e*v and gap to inf.

However, I keep returning a math range error although I believe I have excluded the troublesome E values by using the limits stated above.

Apologies for the vagueness of this question. But, can anybody see obvious mistakes or code misuse?
