Organolead Halide Perovskites for Low Operating Voltage Multilevel Resistive Switching.
Jaeho Choi,Sunghak Park,Joohee Lee,Kootak Hong,Do Hong Kim,Cheon Woo Moon,Gyeong Do Park,Jun Min Suh,Jinyeon Hwang,Soo Young Kim,Hyun Suk Jung,Nam-Gyu Park,Seungwu Han,Ki Tae Nam,Ho Won Jang +14 more
TL;DR: Organolead halide perovskites are used for low-operating-voltage multilevel resistive switching and the migration of iodine interstitials and vacancies with low activation energies is responsible for the low-electric-fieldresistive switching via filament formation and annihilation.
Journal ArticleDOI
Organic–Inorganic Hybrid Halide Perovskites for Memories, Transistors, and Artificial Synapses
TL;DR: HPs have enormous potential to provide a new platform for future electronic devices and explosively intensive studies will pave the way in finding new HP materials beyond conventional silicon-based semiconductors to keep up with "More-than-Moore" times.
Journal ArticleDOI
Palladium Nanoparticles on Assorted Nanostructured Supports: Applications for Suzuki, Heck, and Sonogashira Cross-Coupling Reactions
Kootak Hong,Mohaddeseh Sajjadi,Jun Min Suh,Kaiqiang Zhang,Mahmoud Nasrollahzadeh,Ho Won Jang,Rajender S. Varma,Mohammadreza Shokouhimehr +7 more
TL;DR: Palladium has been the key element for several C-C bond-forming reactions, especially the Nobel-acclaimed Suzuki, Heck, and Sonogashira cross-coupling reactions, among others.

TL;DR: In this paper, the authors demonstrate that wafer-scale, transferable, and transparent thin-film catalysts based on MoS2, which consists of cheap and earth abundant elements, can provide a low onset potential of 1 mA cm−2 at 0.17 V versus a reversible hydrogen electrode and the high photocurrent density of 24.6 m
