General Questions and Answers / MoS2 transmission and the gate voltage

« on: January 7, 2014, 03:50 »

 I was trying to investigate the effect of the gate voltage on the transmission of monolayer MoS2 FETs. I supposed that the transmission spectrum shifts by changing the gate voltage, but ATK results showed no shifts. Are there any mistakes in my calculation?
 I have attached the python file.

General Questions and Answers / Re: band structure of a rectangular supercell

Dear Sir,

 I also have the same question. Angle between the primitive vectors of hexagonal cell with uniaxial strain is not 120 degrees. Is it possible to treat such cell as hexagonal in ATK?

Regards,
N. H.

General Questions and Answers / Complex band of graphene

« on: March 4, 2013, 02:41 »

Dear,

In ATK, I suppose complex band calculation is done along C-axis. How do I define the unit cell to calculate the complex bandstructure of graphene (especially gated bilayer graphene with a gap) along the G-K direction?

Thanks a lot!
