Journal ArticleDOI
Ultrasensitive mechanical crack-based sensor inspired by the spider sensory system
Daeshik Kang,Peter V. Pikhitsa,Yong Whan Choi,Chanseok Lee,Sung Soo Shin,Linfeng Piao,Byeonghak Park,Kahp-Yang Suh,Tae Il Kim,Mansoo Choi +9 more
TL;DR: It is demonstrated that sensors based on nanoscale crack junctions and inspired by the geometry of a spider’s slit organ can attain ultrahigh sensitivity and serve multiple purposes, and that they are applicable to highly selective speech pattern recognition and the detection of physiological signals.
Journal ArticleDOI
Trapped charge-driven degradation of perovskite solar cells
Namyoung Ahn,Kwisung Kwak,Min Seok Jang,Heetae Yoon,Byung Yang Lee,Jong Kwon Lee,Peter V. Pikhitsa,Junseop Byun,Mansoo Choi +8 more
TL;DR: A mechanism for irreversible degradation of perovskite materials in which trapped charges, regardless of the polarity, play a decisive role is uncovered.
Journal ArticleDOI
A novel hybrid carbon material
Albert G. Nasibulin,Peter V. Pikhitsa,Hua Jiang,David P. Brown,Arkady V. Krasheninnikov,Arkady V. Krasheninnikov,Anton S. Anisimov,Paula Queipo,Anna Moisala,Anna Moisala,David Gonzalez,Günther Lientschnig,Abdou Hassanien,Sergey D. Shandakov,Giulio Lolli,Daniel E. Resasco,Mansoo Choi,David Tománek,Esko I. Kauppinen +18 more
TL;DR: The field-emission characteristics of NanoBuds suggest that they may possess advantageous properties compared with single-walled nanotubes or fullerenes alone, or in their non-bonded configurations.
Journal ArticleDOI
Correlation between catalyst particle and single-walled carbon nanotube diameters
TL;DR: In this article, single-walled carbon nanotubes (CNTs) were synthesized at different conditions by a novel aerosol method based on the introduction of pre-formed iron catalyst particles into conditions leading to CNT formation.
Journal ArticleDOI
Parallel patterning of nanoparticles via electrodynamic focusing of charged aerosols
Hyoungchul Kim,Hyoungchul Kim,Jaehyun Kim,Jaehyun Kim,Hongjoo Yang,Hongjoo Yang,Jeong-soo Suh,Jeong-soo Suh,Tae-Young Kim,Tae-Young Kim,Bangwoo Han,Sung-Won Kim,Sung-Won Kim,Dae Seong Kim,Peter V. Pikhitsa,Mansoo Choi +15 more
TL;DR: It is demonstrated that the ion-induced parallel-focusing approach could produce high-resolution patterns at high speed on both conducting (p-type silicon) and non-conducting (silica) surfaces.
