Defect-engineered black tetragonal-tungsten-bronze ferroelectric crystal for full spectrum absorption and broadband photoelectronic conversion

The authors propose a hierarchical defect engineering strategy for ferroelectric oxides to achieve full-spectrum optical absorption and boost broadband self-powered photodetection, realizing self-powered photodetection in the 250–5000 nm range with a responsivity of >1 mA/W.

Unlocking the phase evolution of the hidden non-polar to ferroelectric transition in HfO₂-based bulk crystals

The underlying formation mechanism and evolution of the ferroelectric phase in hafnium dioxide-based crystals is under debate. Here, the authors characterize the phase transitions and reveal the accompanying atomic movements in a co-doped crystal.

Photon-phonon collaboratively pumped laser

Ultrahigh-efficiency and low-threshold yet tunable and compact laser devices are at the base of new functional devices. Here the authors harness a new temperature degree of freedom to realize a tunable photon-phonon collaboratively pumped laser.

Multiphonon-assisted lasing beyond the fluorescence spectrum

As laser action emerges from fluorescence, its emission wavelength lies within the fluorescence spectrum. Exploiting multiphonon processes can take the laser emission far beyond the spectral limits defined by a material’s intrinsic fluorescence.
