Autor: J. H. Jung, Dong Yeol Yun, Taikon Kim, Euidock Ryu, S. H. Lee, Joo Hyung You, Sang-Wook Kim

Publikováno v: Journal of Nanoscience and Nanotechnology. 11:449-452

InP nanoparticles were formed using a solution method, and the InP nanoparticles that were embedded in a polystyrene (PS) layer were formed using the spin-coating method. The transmission electron microscopy images showed that the InP nanoparticles w

Step-Wise Synthesis of InP/ZnS Core−Shell Quantum Dots and the Role of Zinc Acetate

Autor: Sungwoo Kim, Byungki Kim, Euidock Ryu, Sang-Wook Kim, Shinae Jun, Jang Eun-Joo, Hyosook Jang

Publikováno v: Chemistry of Materials. 21:573-575

Highly luminescent and stable InP/ZnS core−shell nanocrystals were developed by stepwise addition of zinc acetate and dodecanethiol to an InP core solution. Zinc acetate plays an important role in surface etching and ZnS shell formation.

Carrier transport mechanisms of bistable memory devices fabricated utilizing core-shell CdSe/ZnSe quantum-dot/multi-walled carbon nanotube hybrid nanocomposites

Autor: Tae Whan Kim, Euidock Ryu, Sang-Wook Kim, Dong Ick Son, Fushan Li

Publikováno v: Nanotechnology. 20(8)

Transmission electron microscopy images showed that conjugation between single core-shell CdSe/ZnSe quantum dots (QDs) and oxidized multi-walled carbon nanotubes (MWCNTs) was achieved through the complexation reaction. Current-voltage (I-V) measureme

Effects of CdSe shell layer on the electrical properties of nonvolatile memory devices fabricated utilizing core-shell CdTe-CdSe nanoparticles embedded in a poly(9-vinylcarbazole) layer

Autor: Tae Whan Kim, Euidock Ryu, Jae Hun Jung, Sang-Wook Kim, Dea Uk Lee, Dong Yeol Yun

Publikováno v: Applied Physics Letters. 96:123302

Nonvolatile memory devices were fabricated with core-shell CdTe-CdSe nanoparticles embedded in a poly(9-vinylcarbazole) (PVK) layer to investigate the variations in the electrical properties due to a CdSe shell layer. Capacitance-voltage measurements

Photovoltaic cells fabricated utilizing core-shell CdSe/ZnSe quantum dot/multiwalled carbon nanotube heterostructures

Autor: Sun Kyun Lee, Tae Whan Kim, Yong-Hoon Cho, Euidock Ryu, Sang-Wook Kim, Fushan Li, Dong Ick Son

Publikováno v: Applied Physics Letters. 95:061911

An efficient quenching of the photoluminescence spectrum was observed for the quantum dot (QD)-multiwalled carbon nanotubes (MWCNTs) nanocomposite. While the lifetime of the blue emission from ZnSe shell was significantly reduced, it did not exhibit
