Function File: coeffs = osc_injection_scottmalliaras (Phib, N0, [Phib_h, P0 ])

Define the model for charge injection and surface recombination at the contacts as described in the papers [1,2]. Phib is the injection barrier potential and N0 is the site density. The optional parameters Phib_h and P0 are the barrier potential and site density for holes, if values are not provided the same values as for electrons are assumed.
