Nonmonotonic Band Gap Evolution in Bent Phosphorene Nanosheets

Eran Rabani and researchers show that fundamental band gaps of phosphorene sheets can be manipulated by as much as 0.7 eV depending on the bending direction.  Their work was published in Physical Review Matter on June 7, 2019.  (article)


Self-sustaining Thermophotonic Circuits

Researchers from Shanhui Fan's group demonstrate that a self-sustaining thermophotonic circuit can be constructed with the potential of significantly enhancing the power density of heat engines that use photons as the working medium.  Their article "Self-sustaining Thermophotonic Circuits" was published in the Proceedings of the National Academy of Sciences on May 22, 2019.  (article)


Spatiotemporal Light Control with Active Metasurfaces

Researchers from Mark Brongersma's group review recent developments toward time-varying metasurfaces and explore the opportunities that adding dynamic control can offer in terms of actively controlling the flow of light.  Their article, "Spatiotemporal Light Control with Active Metasurfaces," was published in Science on May 17, 2019.  (article)



Variational Theory of Nonrelativistic Quantum Electrodynamics

Researchers from Prineha Narang's group have developed a variational theory of general non-relativistic QED systems of coupled light and matter.   Their letter, "Variational Theory of Nonrelativistic Quantum Electrodynamics," was published in Physical Review Letters, May 16, 2019.  (article)

Redefining near-unity luminescence in quantum dots with photothermal threshold quantum yield

Researchers measure near-perfect performance in low-cost semiconductors

Collaborations between the labs of Professors Alberto Salleo and Paul Alivisatos are reported in Science.   They redefine what it means for low-cost semiconductors, called quantum dots, to be near-perfect and find that quantum dots meet quality standards set by more expensive alternatives. "Redefining near-unity luminescence in quantum dots with photothermal threshold quantum yield"   March 15, 2019  (article)
