Designing a Built-In Electric Field for Efficient Energy Electrocatalysis.

ACS Nano, 2022
To utilize intermittent renewable energy as well as achieve the goals of peak carbon dioxide emissions and carbon neutrality, various electrocatalytic devices have been developed. However, the electrocatalytic reactions, e.g., hydrogen evolution reaction/

Efficient Photocatalytic Overall Water Splitting Induced by the Giant Internal Electric Field of a g‐C3N4/rGO/PDIP Z‐Scheme Heterojunction

Advances in Materials, 2021
A graphitic carbon nitride/rGO/perylene diimide polymer (g‐C3N4/rGO/PDIP) Z‐scheme heterojunction is successfully constructed to realize high‐flux charge transfer and efficient photocatalytic overall water splitting.

Electric-field mediated chemistry: uncovering and exploiting the potential of (oriented) electric fields to exert chemical catalysis and reaction control.

Journal of the American Chemical Society, 2020
This Perspective discusses oriented external-electric-fields (OEEF), and other electric-field types, as 'smart reagents', which enable in principle control over wide-ranging aspects of reactivity and structure.

Electric-field control of magnetism in a few-layered van der Waals ferromagnetic semiconductor

Nature Nanotechnology, 2018
Manipulating a quantum state via electrostatic gating has been of great importance for many model systems in nanoelectronics. Until now, however, controlling the electron spins or, more specifically, the magnetism of a system by electric-field tuning has

Disintegration of water drops in an electric field

Proceedings of the Royal Society of London. Series A, Mathematical and physical sciences, 1964
The disintegration of drops in strong electric fields is believed to play an important part in the formation of thunderstorms, at least in those parts of them where no ice crystals are present. Zeleny showed experimentally that disintegration begins as a

Giant Enhancement of Internal Electric Field Boosting Bulk Charge Separation for Photocatalysis

Advances in Materials, 2016
Incorporating carbon into Bi3 O4 Cl enhances its internal electric field by 126 times, which induces a bulk charge separation efficiency (ηbulk ) of 80%.

Electric-field-driven switching of individual magnetic skyrmions.

Nature Nanotechnology, 2016
Controlling magnetism with electric fields is a key challenge to develop future energy-efficient devices. The present magnetic information technology is mainly based on writing processes requiring either local magnetic fields or spin torques, but it has ...

Understanding the rate-dependent J–V hysteresis, slow time component, and aging in CH3NH3PbI3 perovskite solar cells: the role of a compensated electric field

, 2015
In this work we show that the rate-dependent hysteresis seen in current–voltage scans of CH3NH3PbI3 perovskite solar cells is related to a slow field-induced process that tends to cancel the electric field in the device at each applied bias voltage.

Electric-Field-Induced Degradation of Methylammonium Lead Iodide Perovskite Solar Cells.

Journal of Physical Chemistry Letters, 2016
Perovskite solar cells have great potential for high efficiency generation but are subject to the impact of external environmental conditions such as humidity, UV and sun light, temperature, and electric fields.
