Hsueh-Chung Liao,Cheng-Si Tsao,Tsung-Han Lin,Meng-Huan Jao,Chih-Min Chuang,Sheng-Yong Chang,Yu-Ching Huang,Yu-Tsun Shao,Charn-Ying Chen,Chun-Jen Su,U-Ser Jeng,Yang-Fang Chen,Wei-Fang Su +12 more
TL;DR: The nanostructure of poly(3-hexylthiophene) and [6,6]-phenyl-C61-butyric acid methyl ester bulk heterojunction (BHJ) can be tuned by inorganic nanoparticles (INPs) for enhanced solar cell performance and exhibits significantly enhanced electron mobility, external quantum efficiency, and photovoltaic device performance.
Journal ArticleDOI
Bi-hierarchical nanostructures of donor–acceptor copolymer and fullerene for high efficient bulk heterojunction solar cells
Hsueh-Chung Liao,Cheng-Si Tsao,Yu-Tsun Shao,Sheng-Yung Chang,Yu-Ching Huang,Chih-Min Chuang,Tsung-Han Lin,Charn-Ying Chen,Chun-Jen Su,U-Ser Jeng,Yang-Fang Chen,Wei-Fang Su +11 more
TL;DR: In this paper, the authors present quantitative evolution of bi-hierarchical nanostructure of D-A copolymers and fullerenes by employing grazing-incidence small/wide angle X-ray scattering (GISAXS/GIWAXS) techniques and [2,6]-phenyl-C71-butyric acid methyl ester (PCPDTBT/PCBM) BHJ as model materials.

TL;DR: Polar skyrmions are topologically protected structures that can exist in (PbTiO 3 ) n /(SrTiO3 ) n superlattices and it is shown that they have negative permittivity at the surface, and that they can undergo a reversible phase transition with large dielectric tunability under an electric field.
Journal ArticleDOI
Electron ptychography achieves atomic-resolution limits set by lattice vibrations
Zhen Chen,Yi Jiang,Yu-Tsun Shao,Megan E. Holtz,Michal Odstrcil,Manuel Guizar-Sicairos,Isabelle Hanke,Steffen Ganschow,Darrell G. Schlom,Darrell G. Schlom,David A. Muller +10 more
TL;DR: In this paper, the authors demonstrate an instrumental blurring of under 20 picometers by solving the multiple scattering problem and overcoming the aberrations of the electron probe using electron ptychography to recover a linear phase response in thick samples.
Journal ArticleDOI
Coexisting ferromagnetic–antiferromagnetic state in twisted bilayer CrI3
Yang Xu,Yang Xu,Ariana Ray,Yu-Tsun Shao,Shengwei Jiang,Kihong Lee,Daniel Weber,Joshua E. Goldberger,Kenji Watanabe,Takashi Taniguchi,David A. Muller,Kin Fai Mak,Jie Shan +12 more
TL;DR: In this paper, stacking-dependent interlayer exchange interactions in small-twist-angle CrI3 bilayers yield an ordered ground state with coexisting ferromagnetic and antiferromagnetic regions.
