Exciton-related electroluminescence from monolayer MoS2
Yu Ye, Ziliang Ye, Majid Gharghi +4
Excitons in MoS2 dominate the absorption and emission properties of the two-dimensional system. Here, we study the microscopic origin of the electroluminescence from monolayer MoS2…
Electromagnetic approach to ultrathin solar cell efficiencies
A. Niv, M. Gharghi, Z. R. Abrams +2
Current methods for evaluating solar cell efficiencies cannot be applied to extremely thin cells where phenomena from the realm of near field optics prevail. We overcome this probl…
Theoretical Efficiency Comparison between Carrier Multiplication and Down-Conversion 3rd Generation Solar Cell Designs
Z. R. Abrams, A. Niv, C. Gladden +2
Methods of exceeding the detailed balance limit for a single junction solar cell have included down-converting high energy photons to produce two photons; and carrier multiplicatio…
A Carpet Cloak Device for Visible Light
Majid Gharghi, Christopher Gladden, Thomas Zentgraf +4
We report an invisibility carpet cloak device, which is capable of making an object undetectable by visible light. The cloak is designed using quasi conformal mapping and is fabric…
