Time-dependent NEGF
Q&A|Open | Responses: 1
In the time-dependent NEGF equation, given a sigma_in(t,t’) due to the dot, I am getting
an I-V equation that is making it difficult for me to group terms. For instance, looking at...

Degeneracy factor for holes
Q&A|Open | Responses: 1
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+ =...

CQT Lecture 4: Coulomb blockade and Fock space
Online Presentations | 30 Nov 2006 | Contributor(s):: Supriyo Datta
Objective: To illustrate the limitations of the model described in Lectures 2, 3 and introduce a completely different approach based on the concept of Fock space. I believe this will be a key concept in the next stage of development of transport physics.

MOSCNT: code for carbon nanotube transistor simulation
Downloads | 14 Nov 2006 | Contributor(s):: Siyu Koswatta, Jing Guo, Dmitri Nikonov
Ballistic transport in carbon nanotube metal-oxide-semiconductor field-effect transistors (CNT-MOSFETs) is simulated using the Non-equilibrium Green’s function formalism. A cylindrical transistor geometry with wrapped-around gate and doped source/drain regions are assumed. It should be noted that...
