Ionic Liquid based 2D FET
« on: January 24, 2019, 19:07 »
Is it possible in ATK to have a drop of Ionic Liquid (IL) like EMI-TFSI, DEME-TFSI etc. on top of my 2D material based FET for studying transport phenomenon?
I checked the database but there are no ILs present. If this is not possible, I was thinking of creating a slab around the channel and defining dielectric constant inside the slab equal to dielectric constant of  IL and then apply a very high transverse E field.  This will somewhat emulate an IL gated FET. But in order to increase carrier concentration in the channel, the channel needs to be doped. I don't understand how this doping should be done.

Can this slab idea be implemented in ATK?

It is true that QuantumATK does not have any built-in functionality for ionic liquids, but if you know the structure of it, it is possible to build or import it, and then add it.

However, your second approach is probably more feasible. It sounds very much like the approach that is often used, and which is described in this tutorial: https://docs.quantumwise.com/tutorials/inas_p-i-n_junction/inas_p-i-n_junction.html
I suggest you take a look, and see if it can be adapted for your purpose.
