NEGF theory of quantum photovoltaic devices
22 Sep 2011 | Presentation Materials | Contributor(s): Urs Aeberhard
Many high-efficiency photovoltaics concepts require an advanced control and manipulation of the optoelectronic properties of the active device structure, leading to a prominent role of low...
What is the relation between Keldysh and NEGF ?
Closed | Responses: 1
I’m learning NEGF and Keldysh formalism. The latter seems also refereed to as NEGF in the literature. What is the relation between them ? Are they the same...
