kwant.builder.ModesLead

class kwant.builder.ModesLead(modes_func, interface, parameters)

Bases: kwant.builder.Lead

A general lead defined by its modes wave functions.

Parameters

• modes_func (function) – Has the same signature as modes (without the self parameter) and returns the modes of the lead as a tuple of PropagatingModes and StabilizedModes.

• interface – sequence of Site instances

• parameters (sequence of strings) – The parameters on which the lead depends.

Methods

finalized()

Trivial finalization: the object is returned itself.
