ATK I-V計(jì)算腳本問題
|
|
腳本為: #read in the 0 V configuration device_configuration = nlread("benhello.nc",DeviceConfiguration)[0] calculator = device_configuration.calculator() #make a fast Krylov self energy calculator device_algorithm_parameters = DeviceAlgorithmParameters( self_energy_calculator_real=KrylovSelfEnergy(save_self_energies=True, lambda_min=0.1)) # Define bias voltages voltage_list= 0.2 *numpy.arange(-15,16)*Volt #make loop for voltage in voltage_list: # Set new calculator with modified electrode voltages on the configuration # use the self consistent state of the old calculation as starting input. device_configuration.setCalculator( calculator(electrode_voltages=(-0.5*voltage, 0.5*voltage), device_algorithm_parameters=device_algorithm_parameters), initial_state=device_configuration) # Calculate the transmission spectrum transmission_spectrum = TransmissionSpectrum( configuration=device_configuration, energies=numpy.linspace(-3,3,101)*eV, kpoints=MonkhorstPackGrid(3,3), ) #save the results nlsave('au_dtb_au.nc', device_configuration) nlsave('au_dtb_au.nc', transmission_spectrum) 日志提示沒有自洽,請(qǐng)問對(duì)結(jié)果有什么影響?benhello.nc結(jié)構(gòu)優(yōu)化時(shí)候沒有設(shè)置自洽!是否一定需要設(shè)置自洽? |
