Ferroelectric materials, with a spontaneous polarization that is switchable by an applied electric field, are already used in electronics. Furthermore, internal bias in a ferroelectric shifts the whole polarization hysteresis loop, and the ability to control that would add another degree of freedom for device engineering. In this study, controlled deposition of stressed thin films onto ferroelectrics is used to control the internal bias via the flexoelectric effect. With this technique, strain-engineering concepts for silicon integrated circuits can be transferred, with the potential to individually tune myriad ferroelectric straintronic devices in a deeply scaled environment.

The study of cuprate high- superconductors (HTSs) at different charge-doping levels will shed light on the microscopic mechanism for high- superconductivity and its interplay with different symmetry-breaking orders, but the realization of nanostructures with varying doping levels is challenging due to the chemical instability of the materials. The authors develop an electromigration technique to tune the doping level of YBCO nanowires , which enables studying the (possibly entire) phase diagram in a single nanowire. This approach will benefit the applications of cuprate HTSs, and can be extended to other mesoscopic systems that require tailoring of doping.

The resistive switching induced in Mott materials by a strong applied voltage allows for artificial spiking neurons with great potential. However, controlling the resistive collapse is a challenge, as we lack physical understanding of the phenomenon. Here numerical simulations and experiments reveal how thermal and electronic effects jointly contribute to the phenomenon. The resistive collapse is intrinsically stochastic, and more surprisingly it is a Poissonian process with an exponential escape rate, just like the firing of actual biological neurons. This result provides an unexpectedly realistic aspect to the implementation of tomorrow’s energy-efficient neurocomputing hardware.

Acoustic metamaterials hold great potential for applications in the sensing and control of sound waves. These materials rely on their geometry, not their composition, for functionality, but their geometric configurations are usually fixed when they are fabricated, limiting their potential. In this study, researchers exploit the reversibility, reprogrammability, and inherently nondestructive nature of nonlinear magnetic lattices to engineer the propagation of sound waves through two distinct configurations (phases) of a metamaterial. Harnessing the unique wave-control properties of each phase yields a robust wave filter for ultralow-frequency sound waves that is in real time.

In atomic sensors, continuous interrogation of laser-cooled atoms carries the benefits of improved sensitivity and high measurement bandwidth. However, cooling in proximity to coherent atomic state evolution can degrade performance in compact systems, due to decoherence. This study demonstrates an inertially sensitive matter-wave interferometer in a three-dimensionally-cooled atomic beam that mitigates decoherence while operating continuously. The technique could enable compact atom-interferometer sensors that measure continuously and with high sensitivity on dynamic platforms.

Understanding exciton diffusion in organic solar cells is crucial to understanding the recent rise in power-conversion efficiencies afforded by using non-fullerene acceptor molecules (NFAs). This study introduces a technique called pulsed-PLQY for measuring exciton diffusion lengths in organic semiconductors. Compared to existing techniques, pulsed-PLQY is faster, easier, requires less specialized equipment, and is less sensitive to experimental conditions. Using this method, the authors find that modern non-fullerene acceptor semiconductors exhibit longer diffusion lengths than their fullerene forerunners, and that this increase is driven by increases in diffusivity.

Quick and easy methods for developing a stable three-dimensional (3D) structure from a planar sheet form a rapidly expanding area of research. While origami and kirigami provide a variety of concepts and designs for engineering, a physical understanding of the underlying mechanics is still elusive. The authors introduce a class of designs for 2D-to-3D shape-shifting materials: pop-up origami extended with chiral cuts. Experiments and simulations elucidate the basic actuation mechanism, and reveal superior load-bearing ability, thanks to a self-locking mechanism. This proof of concept for the “ori-kirigami” design will promote its use in industrial, artistic, and architectural systems.

The authors demonstrate a prototype of an electrically injected, circularly polarized near-infrared laser based on a specifically engineered chiral microcavity. Importantly, the high degree of polarization of the emitted coherent beam is determined by the chirality of the imprinted structure, which is based on an optical cavity with a gradually doped GaAs/AlAs distributed Bragg reflector. A two-step lithographic process was used to fabricate the chiral structures, in combination with electrical injectors. This device represents a key step toward utilizing chiral microcavities in real-world applications.

Although the advantageous properties of ferromagnetic Co-Fe-B spintronic devices (including their controllability through thermal annealing) have been recognized, there have been few reports on devices with Co-Fe-B. This study reports Nb/CoFeB/Nb Josephson devices in which the critical current is enhanced by up to 700% following thermal annealing, due to improved structural order of the Co-Fe-B barrier. The results offer a platform for the development of energy-efficient, high-performance superconducting spintronic devices.

Stretch here, not there: Programmable tailoring of a wave’s group velocity in space, achieved via synthetic impedance circuitry with digital signal processing, enables substantial design flexibility for devices. Here researchers demonstrate the programming of “rainbow trapping” (slowing waves to a temporary stop, based on frequency) in an elastic waveguide for chosen spatial grading profiles. The use of spatially graded resonators also significantly enhances the band gap’s bandwidth, beyond that for a uniform resonator. This class of metamaterials enables simple on-demand programming of elastic wave trapping, spatial filtering, and attenuation through a digital interface.

Understanding exciton diffusion in organic solar cells is crucial to understanding the recent rise in power-conversion efficiencies afforded by using non-fullerene acceptor molecules (NFAs). This study introduces a technique called pulsed-PLQY for measuring exciton diffusion lengths in organic semiconductors. Compared to existing techniques, pulsed-PLQY is faster, easier, requires less specialized equipment, and is less sensitive to experimental conditions. Using this method, the authors find that modern non-fullerene acceptor semiconductors exhibit longer diffusion lengths than their fullerene forerunners, and that this increase is driven by increases in diffusivity.

The authors review the past, present, and possible future of interband quantum cascade photodetectors (IB QCPs) based on type-II superlattices of semiconductors, in the context of high-operating-temperature (HOT) conditions for infrared technologies. Emerging trends related to IB-QCP detectivity and response time are discussed in terms of commonly used benchmarks, to promote the development of IR HOT optoelectronics.
