Persistent Enhancement of Exciton Diffusivity in CsPbBr3 Nanocrystal Solids
Wenbi Shcherbakov-Wu, Seryio Saris, Thomas Sheehan +6
In semiconductors, exciton or charge carrier diffusivity is typically described as an inherent material property. Here, we show that the transport of excitons (i.e., bound electron…
Terahertz Field-Induced Reemergence of Quenched Photoluminescence in Quantum Dots
Jiaojian Shi, Frank Y. Gao, Zhuquan Zhang +13
Continuous and concerted development of colloidal quantum-dot light-emitting diodes over the past two decades has established them as a bedrock technology for the next generation o…
All-optical fluorescence blinking control in quantum dots with ultrafast mid-infrared pulses
Jiaojian Shi, Weiwei Sun, Hendrik Utzat +7
Photoluminescence (PL) intermittency is a ubiquitous phenomenon detrimentally reducing the temporal emission intensity stability of single colloidal quantum dots (CQDs) and the emi…
The Enhancement of Interfacial Exciton Dissociation by Energetic Disorder is a Nonequilibrium Effect
Liang Shi, Chee Kong Lee, Adam P. Willard
The dissociation of excited electron-hole pairs is a microscopic process that is fundamental to the performance of photovoltaic systems. For this process to be successful, the oppo…
Exciton Trapping Is Responsible for the Long Apparent Lifetime in Acid-Treated MoS2
Aaron J. Goodman, Adam P. Willard, William A. Tisdale
Here, we show that deep trapped "dark" exciton states are responsible for the surprisingly long lifetime of band-edge photoluminescence in acid-treated single-layer MoS2. Temperatu…
