Title: Projected local density of states
Post by: bfazi on November 5, 2016, 22:27

Hello,
I have calculated Projected local density of states (PLDOS) of a FET.  Result showed PLDOS of channel and PLDOS of the source and drain have not shown. Is it possible to obtain PLDOS of the whole of device including source, channel and drain in ATK?

It cannot be done automatically, because the calculations of the electrodes and that of the central region are actually 3 differentet calculations.

However, the PLDOS includes the electrodes extensions. If your device is modeled correctly, then the PLDOS (that is, the electronic structure) at the left/right boundary of the PLDOS plot should be the same as that in the bulk electrodes.
