Manipulating Ferroelectricity Without Electrical Bias: A Perspective

open access: yesAdvanced Physics Research, EarlyView.
Alternatives to electrical bias to control ferroelectric polarization are highly desired for the development of ferroelectric‐based applications. The polarizing role of chemically engineered surfaces, the impact of chemical substitution and mechanical pressure, and light‐induced effects on the final polarization state are highlighted in this short ...

Broadband Conductance Matching Effect in Conductive Metamirrors

open access: yesAdvanced Physics Research, EarlyView.
A conductance matching effect is revealed in conductive metamirrors whose input conductance can be broadband self‐matched to the free space when the conductivity‐thickness product equals 8 mS. This effect enables thickness‐invariant perfect absorption at low frequencies, and tunable resonances at higher‐order modes, providing new opportunities for ...

Interconversion of Optical to Terahertz Pulses in Nonlinear Beta Barium Borate Crystal

open access: yesAdvanced Physics Research, EarlyView.
ABSTRACT Low‐temperature β‐phase barium borate (β‐BBO) is an important nonlinear crystal, widely utilized for optical second‐harmonic (SH) generation. Recent re‐measurements of refractive indices in the terahertz (THz) range reveal that β‐BBO is a positive uniaxial crystal.

Molten Zinc Coordination Polymer Glass as a Host for Stable and Processable Optical Dye Composites

open access: yesEcoEnergy, EarlyView.
Zinc‐based coordination polymer glass is employed to suppress aggregation‐caused quenching (ACQ) and enhance molecular stability, enabling improved luminescence performance in the solid state. The emission color of the hybrid composites can be tuned by varying the incorporated guest molecules, while the glass matrix effectively prevents aggregation and

Bio‐Inspired Ordered WO3 Nano‐Helixes Enable Multi‐Band Electrochromic Smart Windows with Ultrafast Switching and Robust Cyclability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...
