Ultralow-voltage operation of light-emitting diodes
Yaxiao Lian, Dongchen Lan, Shiyu Xing +5
The radiative recombination of injected charge carriers gives rise to electroluminescence (EL), a central process for light-emitting diode (LED) operation. It is often presumed in…
High-performance green and blue quantum-dot light-emitting diodes with eliminated charge leakage
Yunzhou Deng, Feng Peng, Yao Lu +12
Quantum-dot light-emitting diodes (QD-LEDs) promise a new generation of efficient, low-cost, large-area, and flexible electroluminescent devices. However, the inferior performance…
Deciphering exciton-generation processes in quantum-dot electroluminescence
Yunzhou Deng, Xing Lin, Wei Fang +5
Electroluminescence (EL) of colloidal nanocrystals promises a new generation of high-performance and solution-processable light-emitting diodes (LEDs). The operation of nanocrystal…
Efficient and ultra-stable perovskite light-emitting diodes
Bingbing Guo, Runchen Lai, Sijie Jiang +12
Perovskite light-emitting diodes (PeLEDs) have emerged as a strong contender for next-generation display and information technologies. However, similar to perovskite solar cells, t…

Lei Zhang, Jing Pan, Zhang Zhang +12
Electronic skin, a class of wearable electronic sensors that mimic the functionalities of human skin, has made remarkable success in applications including health monitoring, human…
Highly efficient light-emitting diodes based on intramolecular rotation
Dawei Di, Alexander S. Romanov, Le Yang +5
The efficiency of an organic light-emitting diode (OLED) is fundamentally governed by the spin of recombining electron-hole pairs (singlet and triplet excitons), since triplets can…
Photonically-confined solar cells: prospects for exceeding the Shockley-Queisser limit
Qian Zhou, Arfa Karani, Yaxiao Lian +3
The Shockley-Queisser (SQ) limit, introduced by W. Shockley and H. J. Queisser in 1961, is the most well-established fundamental efficiency limit for single-junction photovoltaic s…
High-efficiency perovskite-polymer bulk heterostructure light-emitting diodes
Baodan Zhao, Sai Bai, Vincent Kim +17
Perovskite-based optoelectronic devices have gained significant attention due to their remarkable performance and low processing cost, particularly for solar cells. However, for pe…
