ANGEL - A Nonequilibrium Green's Function Solver for LEDs
07 Feb 2010 | Contributor(s):: sebastian steiger
Introducing ANGEL, a Nonequilibrium Green’s Function code aimed at describing LEDs.ANGEL uses a description close to the classic NEMO-1D paper (Lake et al., JAP 81, 7845 (1997)) to model quantum transport in a light-emitting diode (LED).ANGEL is the first 1D-heterostructure NEGF to include the...

Metamaterials with low loss and gain
28 Jan 2010 | | Contributor(s):: Mikhail A. Noginov
Optical loss caused by absorption in metal and a need for active control are among the major challenges of plasmonic metamaterials. Both can be addressed by utilizing optical gain. Recent efforts aimed at the reduction of loss and the stimulated emission in nanoplasmonic systems with gain will be...
