I'm using the z shaped device in this tutorial:

https://docs.quantumwise.com/v2017/tutorials/vnl_graphene_transistor/vnl_graphene_transistor.htmlI calculated the transmission spectrum for different configurations.

I need to calculate the conductance and current for different bias voltages so I'm using the below code:

transmission_spectrum = nlread("Device 1.hdf5",TransmissionSpectrum)[0]

temperature_list=numpy.linspace(300,300,1)*Kelvin

conductance_list=numpy.zeros(len(temperature_list))

current_list=numpy.zeros(len(temperature_list))

for i in range(len(temperature_list)):

current_list

*=transmission_spectrum.current( electrode_temperatures=(temperature_list**, temperature_list**),electrode_voltages=(0.25*Volt,-0.25*Volt))*

conductance_list*=transmission_spectrum.conductance( electrode_temperatures=(temperature_list**, temperature_list**),electrode_voltages=(0.25*Volt,-0.25*Volt))*

I was getting the current from IV analysis but I was getting high conductance with low current. The relation was not direct proportion.

After using this code the results are direct proportion.

How can I be sure that my results are right?

Can I get current and conductance from same transmission spectrum at different bias voltages?

Thanks
