Significant Lifetime Enhancement in QLEDs by Reducing Interfacial Charge Accumulation via Fluorine Incorporation in the ZnO Electron Transport Layer
Autor: Dong Seob Chung, Tyler Davidson-Hall, Giovanni Cotella, Quan Lyu, Peter Chun, Hany Aziz
Publikováno v: Nano-Micro Letters, Vol 14, Iss 1, Pp 1-15 (2022)
Abstract ZnO nanoparticles are widely used for the electron transport layers (ETLs) of quantum dots light emitting devices (QLEDs). In this work we show that incorporating fluorine (F) into the ZnO ETL results in significant enhancement in device ele

Significant enhancement in quantum-dot light emitting device stability via a ZnO:polyethylenimine mixture in the electron transport layer
Autor: Tyler Davidson-Hall, Fatemeh Samaeifar, Peter Chun, Hyeonghwa Yu, Hany Aziz, Giovanni Cotella, Quan Lyu, Dong Seob Chung
Publikováno v: Nanoscale Advances. 3:5900-5907
The effect of adding polyethylenimine (PEI) into the ZnO electron transport layer (ETL) of inverted quantum dot (QD) light emitting devices (QDLEDs) to form a blended ZnO:PEI ETL instead of using it in a separate layer in a bilayer ZnO/PEI ETL is inv

Electrically Tunable Slow Light Using Graphene Metamaterials
Autor: Hyeon-Don Kim, Dong Seob Chung, Taewoo Ha, Rongkuo Zhao, Sang Soon Oh, Young Hee Lee, Bumki Min, Shuang Zhang, Teun-Teun Kim
Publikováno v: ACS Photonics
Metamaterials with classical analogues of electromagnetically induced transparency open new avenues in photonics for realizing smaller, more efficient slow light devices without quantum approaches. However, most of the metamaterial-based slow light d

Oxidation Effect in Octahedral Hafnium Disulfide Thin Film
Autor: Thuc Hue Ly, Taesoo Kim, Honggi Nam, Hyunyeong Na, Hyun Kim, Youngjo Jin, David J. Perello, Hye Yun Jeong, Sang Hoon Chae, Young Hee Lee, Dong Seob Chung
Publikováno v: ACS Nano. 10:1309-1316
Atomically smooth van der Waals materials are structurally stable in a monolayer and a few layers but are susceptible to oxygen-rich environments. In particular, recently emerging materials such as black phosphorus and perovskite have revealed strong
