(IF 30.849) Pub Date : 2022-06-20 Wei Gao, Feng Qi, Zhengxing Peng, Francis R. Lin, Kui Jiang, Cheng Zhong, Werner Kaminsky, Zhiqiang Guan, Chun-Sing Lee, Tobin J. Marks, Harald Ade, Alex K.-Y. Jen
A record power conversion efficiency (PCE) of over 19% has been realized in planar-mixed heterojunction (PMHJ) organic solar cells (OSCs) by adopting the asymmetric selenium substitution strategy in making a pseudo-symmetric electron acceptor, BS3TSe-4F. The combined molecular asymmetry with more polarizable selenium substitution increases the dielectric constant of D18/BS3TSe-4F blend, helping lower

Complex oxides for brain-inspired computing: A review Adv. Mater. (IF 30.849) Pub Date : 2022-06-20 Tae Joon Park, Sunbin Deng, Sukriti Manna, A. N. M. Nafiul Islam, Haoming Yu, Yifan Yuan, Dillon D. Fong, Alexander A. Chubykin, Abhronil Sengupta, Subramanian K.R.S. Sankaranarayanan, Shriram Ramanathan
The fields of brain-inspired computing, robotics, and, more broadly, artificial intelligence seek to implement knowledge gleaned from the natural world into human-designed electronics and machines. Most advances to date have happened in software and algorithms. However, there is growing interest in designing hardware, i.e., new semiconductor materials and devices and their interconnections that can

Thermal Shock Fabrication of Ion-stabilized Perovskite and Solar Cells Adv. Mater. (IF 30.849) Pub Date : 2022-06-20 Yifei Kang, Anran Wang, Rong Li, Yilong Song, Xinjiang Wang, Hanming Li, Weiqing Xu, Lijun Zhang, Qingfeng Dong
Here we show a highly crystalline perovskite grain structure with compressed surface lattice realized by a thermal-shocking fabrication. The strained perovskite grain structure is stabilized by Cl–-reinforcing surface lattice and show enhanced bonding energy and ionic activation temperature, which contributes to hysteresis-free operation of perovskite solar cells (PSCs) at much higher temperature up

Nonvolatile control of metal-insulator transition in VO2 by ferroelectric gating Adv. Mater. (IF 30.849) Pub Date : 2022-06-17 Yoon Jung Lee, Kootak Hong, Kyeongho Na, Jiwoong Yang, Tae Hyung Lee, Byungsoo Kim, Chung Wung Bark, Jae Young Kim, Sung Hyuk Park, Sanghan Lee, Ho Won Jang
Controlling phase transitions in correlated materials yields emergent functional properties, providing new aspects to future electronics and a fundamental understanding of condensed matter systems. With vanadium dioxide (VO2), a representative correlated material, we develop an approach to control a metal-insulator transition (MIT) behavior by employing a heteroepitaxial structure with a ferroelectric

Brushed Metals for Rechargeable Metal Batteries Adv. Mater. (IF 30.849) Pub Date : 2022-06-16 Weiyin Chen, Rodrigo V. Salvatierra, John T. Li, Duy X. Luong, Jacob L. Beckham, Victor D. Li, Nghi La, Jianan Xu, James M. Tour
Battery designs are swiftly changing from metal-ion to rechargeable metal batteries. Theoretically, metals can deliver maximum anode capacity and enable cells with improved energy density. In practice, these advantages are only possible if the parasitic surface reactions associated with metal anodes are controlled. These undesirable surface reactions are responsible for many troublesome issues, like

A Single-Dot Perovskite Spectrometer Adv. Mater. (IF 30.849) Pub Date : 2022-06-15 Linqi Guo, Haoxuan Sun, Min Wang, Meng Wang, Liangliang Min, Fengren Cao, Wei Tian, Liang Li
There are significant applications for miniature on-chip spectrometers in many fields. However, at present, on-chip spectrometers have to utilize an integrated strategy to achieve spectral analysis, which undoubtedly squanders the photosensitive area and adds pressure to the miniaturization of the spectrometer. Here, we demonstrate a unique spectrometer design that adopts a single detection point with
