electrode not perfect

Respected Quantumwise Team

when I build the device the electrode breaks show. How can build the perfect electrode in device.

please suggest to me.


Thanks

Perfect electrode means periodic electrode, so that you will have to attach a semiinfinite periodic structure to your carbon cones on the left and right side of the point contact to be able to build a device configuration.

That is totally up to you how to build it. I believe there is no way of making perfect periodic cone without breaking it - this is what QATK did for you. If you want a smooth transition between the scattering/central region and the electrodes, you have to decide on what kind of electrodes you want to attach to the central region.

I guess you could use a periodic carbon nanotube for the electrodes - the cones should only be in the central region.
