[求助]
計算的I-V曲線還是一個點(diǎn),請幫忙檢查
|
|
想計算連續(xù)偏壓,得到I-V曲線,首先在VNL,scriper得到基本設(shè)置及計算腳本,施加偏壓部分如下: #---------------------------------------- # Device Calculator #---------------------------------------- calculator = DeviceLCAOCalculator( basis_set=basis_set, exchange_correlation=exchange_correlation, numerical_accuracy_parameters=device_numerical_accuracy_parameters, electrode_calculators= [left_electrode_calculator, right_electrode_calculator], ) device_configuration.setCalculator(calculator) nlprint(device_configuration) device_configuration.update() nlsave('D:/ATK/2/voltage3.nc', device_configuration) # ------------------------------------------------------------- # Transmission spectrum # ------------------------------------------------------------- 根據(jù)手冊和個人理解,修改如下: #---------------------------------------- # Device Calculator #---------------------------------------- voltage_list=numpy.linspace(0.0,1.0,5)*Volt for voltage in voltage_list: calculator = DeviceLCAOCalculator( basis_set=basis_set, exchange_correlation=exchange_correlation, numerical_accuracy_parameters=device_numerical_accuracy_parameters, electrode_calculators= [left_electrode_calculator, right_electrode_calculator], electrode_voltages=(0.5*voltage,-0.5*voltage) ) device_configuration.setCalculator(calculator) nlprint(device_configuration) device_configuration.update() nlsave('D:/ATK/2/voltage3.nc', device_configuration) # ------------------------------------------------------------- # Transmission spectrum # ------------------------------------------------------------- 得到的I-V曲線還是一個點(diǎn),請教各位高手,應(yīng)該如何處理? |
