Journal ArticleDOI
Reversible Halide Exchange Reaction of Organometal Trihalide Perovskite Colloidal Nanocrystals for Full-Range Band Gap Tuning
Dong Myung Jang,Kidong Park,Duk Hwan Kim,Jeunghee Park,Fazel Shojaei,Hong Seok Kang,Jae Pyung Ahn,Jong Woon Lee,Jae Kyu Song +8 more
TL;DR: A remarkable finding of reversible halide-exchange reactions of MAPbX3 is reported, which facilitates the synthesis of a series of mixed halide perovskite series, including those with I-rich composition, which exhibited the highest photoconversion efficiency.
Journal ArticleDOI
X-ray photoelectron spectroscopy and first principles calculation of BCN nanotubes.
Shin Young Kim,Jeunghee Park,Hyun Chul Choi,Jae Pyung Ahn,Jin Qiang Hou,‖,⊥ and,Hong Seok Kang +5 more
TL;DR: Using the first principles method, the relative stabilities and electronic structures of the various isomers of the double-walled boron carbonitride nanotubes with two different structures were investigated; the C-outerlayer BN nanotube structure is the most stable isomer.
Journal ArticleDOI
Red-to-Ultraviolet Emission Tuning of Two-Dimensional Gallium Sulfide/Selenide.
Chan Su Jung,Fazel Shojaei,Kidong Park,Jin Young Oh,Hyungsoon Im,Dong Myung Jang,Jeunghee Park,Hong Seok Kang +7 more
TL;DR: Graphene-like two-dimensional nanostructures have attracted significant attention because of their unique quantum confinement effect at the 2D limit, and a wide Eg tuning over the visible-to-UV range could provide an insight for the realization of full-colored flexible and transparent light emitters and displays.
Journal ArticleDOI
Nitrogen-Doped Graphitic Layers Deposited on Silicon Nanowires for Efficient Lithium-Ion Battery Anodes
Yong Jae Cho,Han Sung Kim,Hyungsoon Im,Yoon Myung,Gyeong Bok Jung,Chi-Woo Lee,Jeunghee Park,Mi-Hee Park,Jaephil Cho,Hong Seok Kang +9 more
TL;DR: In this paper, Nitrogen (N)-doped graphitic layers were deposited as shells on pregrown silicon nanowires by chemical vapor deposition, and graphite-like and pyridine-like structures were selectively chosen for 3 and 10% N doping, respectively.
Journal ArticleDOI
Tetragonal phase germanium nanocrystals in lithium ion batteries.
Yong Jae Cho,Hyungsoon Im,Han Sung Kim,Yoon Myung,Seung Hyuk Back,Young Rok Lim,Chan Su Jung,Dong Myung Jang,Jeunghee Park,Eun Hee Cha,Won Il Cho,Fazel Shojaei,Hong Seok Kang +12 more
TL;DR: Comparative studies on the cycle-dependent lithiation/delithiation processes of germanium-based nanostructures show that metastable tetragonal (ST12) phase Ge NCs were constantly produced upon lithiation and became the dominant phase after a few cycles, completely replacing the original phase.
