General Questions and Answers / Gap of Graphene Ribbon

« on: July 23, 2011, 04:05 »

I took a caculation of a system with two graphene ribbons as a pair of electrodes. The width of the ribbons is N=7, implying that there exists a gap of about 0.5eV. However, the transmission spectra of ATK showed that the conductivity is not zero around zero energy. How can this phenomenon be explained?
Thanks!

Installation and License Questions / Need a new license?

« on: April 14, 2010, 15:41 »

I have got a license for my one notebook and it works well. Do I need to apply for a new one if I want to install ATK in another computer?(The system is different. One is Windows and the other one is Linux.)
What shall I do if the new license is needed but the second computer can not get online?
Wait for your help~
