Efficient Energy Transport in an Organic Semiconductor Mediated by Transient Exciton Delocalization
Alexander J. Sneyd, Tomoya Fukui, David Palecek +15
Efficient energy transport is highly desirable for organic semiconductor (OSC) devices such as photovoltaics, photodetectors, and photocatalytic systems. However, photo-generated e…
Bandgap Control in Two-Dimensional Semiconductors via Coherent Doping of Plasmonic Hot Electrons
Yu-Hui Chen, Ronnie R. Tamming, Kai Chen +6
Bandgap control is of central importance for semiconductor technologies. The traditional means of control is to dope the lattice chemically, electrically or optically with charge c…
Anapole mediated giant photothermal nonlinearity in nanostructured silicon
Tianyue Zhang, Ying Che, Kai Chen +14
Featured with a plethora of electric and magnetic Mie resonances, high index dielectric nanostructures offer a versatile platform to concentrate light-matter interactions at the na…
Ultrafast Triplet Pair Formation and Subsequent Thermally Activated Dissociation Control Efficient Endothermic Singlet Exciton Fission
Hannah L. Stern, Alexandre Cheminal, Shane R. Yost +12
Singlet exciton fission (SF), the conversion of one spin-singlet exciton (S1) into two spin-triplet excitons (T1), could provide a means to overcome the Shockley-Queisser limit in…
Electromechanically Tunable Suspended Optical Nano-antenna
Kai Chen, Gary Razinskas, Thorsten Feichtner +3
Coupling mechanical degrees of freedom with plasmonic resonances has potential applications in optomechanics, sensing, and active plasmonics. Here we demonstrate a suspended two-wi…
