« on: May 13, 2015, 07:46 »

Dear sir

    how can to see the  atomic charge of per atom of any device system . I also calculate mulliken population analysis but as a given of print data .
    so how to indicate the atomic charge of per atom of device as attach of fig. I use  ATK 12.2.2

  please suggest to me

          thanks

Dear sir


              I calculate the plot of Total energy as function of the gate voltage.

              Different curves are for charge states −2, −1, 0, 1, 2 must be straight lines or curved form.
              I attached the image of plot which is right or not. please suggest to me.


            thanks

General Questions and Answers / transmission

« on: January 10, 2015, 15:43 »

  Dear All
              I am new atk user and use  ATK 12.2.2
              how to calculate transmission for different voltage. as example if we calculate transmission for 0.94 volt.
              if we take
                   ( A)       left electrode 0.47  and right electrode -0.47 ev
                    (B)        left electrode 0  and right electrode 0.94
                    ( c)       left electrode 0.94  and right electrode -0.94



                        which procedure is correct A,B and c please suggest to me





             thanks

General Questions and Answers / I-V curve calculation

« on: October 6, 2014, 08:12 »

Dear sir

      I want to calculate I-V curve of a graphene device .ATK 12.2.2 version.
      but I used of two method given  for calculation of I-V curve but I confused of find which method is correct for calculation of I-V curve.
      please suggest to me. I attached of M.S word file please to see and suggest to me which method is right for calculation of I-V curve
      for device.


  thanks
