How to model electrical transport in large conductors?
http://nanohub.org/answers/question/1154
http://nanohub.org/answers/question/1154
For modeling electrical transport in large conductors one has to consider the inter unit coupling energy(t) as the reason behind the level broadening in the unit cells. My questions are :Is inter unit coupling energy(t)the only parameter behind the level broadening in large...]]>

In the timedependent NEGF equation, given a sigma_in(t,t’) due to the dot, I am gettingan IV equation that is making it difficult for me to group terms. For instance, looking at theanalogue of the first term ofI = 2q/hbar. int dE Tr

Degeneracy factor for holes
http://nanohub.org/answers/question/3
http://nanohub.org/answers/question/3
You calculate the occupation of donor states in your book by requiring that only (00, 01, 10) states are possible. Therefore, the probability that donor states are unoccupied is:
ND+ = ND*f_00 = ND/ + 2...]]>
