Structurally Engineered Nanocrystal Quantum Dots for Light-Emitting Applications
배완기 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0
In this talk, I will present how the structural features of NQDs correlate with their optical properties and the device performances. Specifically, I explain the optical and electrical properties (i.e., single exciton and multi-carrier dynamics) of NQDs in respect to their size and shape. In addition I provide the relationship between the optical and electrical properties of NQDs with the performances of corresponding devices. Furthermore, I introduce recent achievements for high performance light-emitting diodes enabled by the structurally engineered NQDs. At the end, I discuss the state-of-the-art of NQD based optoelectronic applications and their potentials/limitations for practical realization.
Structurally engineered nanocrystal quantum dots for optoelectronic applications
배완기 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.1
Freestanding nanocrystal quantum dots (NQDs) promise the next-generation optoelectronic applications ranging from color-saturated light emitting systems to high-efficiency photo-responsive devices based on the cost-effective solution processing methods. Recent studies have unveiled that the structural features of NQDs govern the carrier dynamics within individual NQDs and NQD assemblies and thus have a significant impact on the performances of optoelectronic devices. In this talk, I will present how the structural features of NQDs correlate with their optical properties and the device performances. Specifically, I explain the optical and electrical properties (i.e., single exciton and multi-carrier dynamics) of NQDs in respect to their size and shape. In addition I provide the relationship between the optical and electrical properties of NQDs with the performances of corresponding devices. Furthermore, I introduce recent achievements for high performance light-emitting diodes and photovoltaic devices enabled by the structurally engineered NQDs. At the end, I discuss the state-of-the-art of NQD based optoelectronic applications and their potentials/limitations for practical realization.
