Title: mos2 FET
Post by: divyaling on August 26, 2016, 13:55

hi,

Am using ATK 2015.1. Can anyone tell me how to create MoS2 FET. please help me by giving some reference.

Thanks in advance.

You may take a look at the following two tutorials, http://docs.quantumwise.com/tutorials/vnl_graphene_transistor/vnl_graphene_transistor.html?highlight=transistor
http://docs.quantumwise.com/tutorials/transmission_gr_mos2/transmission_gr_mos2.html?highlight=mos2.

Thanks for the reply. If i add from plugin ->nanoribbon --> chemical properties .(for graphene it will show like carbon and carbon)

For my case(mos2), as like tutorial i can choose one molybdenum and one sulfur. how can i choose the Molybdenum and disulfide.? pls reply.
Thank you.

Please go through the second example on MoS2 in the  tutorial http://docs.quantumwise.com/tutorials/transmission_gr_mos2/transmission_gr_mos2.html?highlight=mos2. You may adopt the bulk MoS2 structure from the Database, and then modify it in the Builder.

- Locate molybdenite in the crystal database and add it to the stash.
- Remove one layer, leaving only 3 atoms in the unit cell.
- Then perform the same transformation to the orthorhombic structure as for graphene above.
- As an additional step, open Coordinate Tools>Center and center the atoms in all directions.
