ThermoElectric.tau_2d_cylinder

ThermoElectric.tau_2d_cylinder(energy: numpy.ndarray, num_kpoints: numpy.ndarray, Uo: float, relative_mass: numpy.ndarray, volume_frac: float, valley: numpy.ndarray, dk_len: float, ro: numpy.ndarray, lattice_parameter: float, n_sample=2000) → numpy.ndarray

A fast algorithm that uses Fermi’s golden rule to compute the energy dependent electron scattering rate from cylindrical nano-particles or nano-scale pores infinitely extended perpendicular to the current.

Parameters

• energy (np.ndarray) – Energy range

• num_kpoints (np.ndarray) – Number of kpoints in each direction

• Uo (float) – Barrier height

• relative_mass (np.ndarray) – Relative mass of electron

• volume_frac (float) – Defects volume fraction

• valley (np.ndarray) – Conduction band valley indices

• dk_len (float) – Sample size

• ro (np.ndarray) – Cylinder radius

• lattice_parameter (float) – lattice parameter

• n_sample (int) – Mesh sample size

Returns

tau_cylinder – Electron-defect lifetime

Return type

np.ndarray
