Title: noise calculation
Post by: kanna on March 3, 2016, 20:11

Hi,
Is there a way to calculate noise in a device with ATK ?

Regards

You have to first think about the source of noise in device. 

The I-V curve of a device simulation is based on the ideal case (e.g., zero temperature for lattice atoms, no impurity scattering for electron transport, under DC voltage and so on).

1/f noise depends on the material properties which I think is not possible under NEGF.
Will thermal noise (which is modeled by a resistor) be captured in the newly added electron phonon interaction feature ?
