All-inorganic halide perovskites have thus far exhibited better thermal stability but lower power conversion efficiency (PCE), compared with their organic–inorganic hybrid counterparts. The experimentally observed nonradiative recombination loss is commonly attributed to the prevalence of native deep defects, yet exact microscopic origin remains elusive. Based on density functional theory calcu...

Repeated uniform switching of the magnetization thin films ferrimagnetic amorphous Gd x (FeCo) 1?x in response to single fast laser pulses is well established. Here, we report unusual toggle sperimagnetic Dy Co and Tb with ? 0.25 irradiated 200 fs 800 nm light. The samples have strong local random anisotropy due non-S state rare earth. compensation temperature ?180 K, their Curie ?500 K. They a...

A new strategy for the stable operation of high energy, solid-state Na batteries by operating symmetric cells at elevated pressures is demonstrated. Enhanced interface kinetics are achieved a stack pressure 100 MPa and temperature 50°C, evident lowering voltage polarization 10 times. More details can be found in article number 2200658, Milana Trifkovic co-workers.

All-inorganic halide perovskite materials have recently emerged as outstanding for optoelectronic applications. However, although critical developing novel technologies, the influence of charge traps on transport in all-inorganic systems still remains elusive. Here, properties cesium lead bromide, nanowire films are probed using a field-effect transistor geometry. Field-effect mobilities ?FET =...

We demonstrate a successful process scheme for the integration of CMOS-compatible ferroelectric gate stack on scaled vertical InAs nanowire gate-all-around MOSFET silicon. The devices show promising device characteristics with nanosecond write time and large memory window >1.5 V. In current implementation, performance is mainly limited by access resistance, which attributed to thermal sensitivi...

Many biological invasions do not occur as a gradual expansion along a continuous front, but result from the expansion of satellite populations that become established at 'invasion hubs'. Although theoretical studies indicate that targeting control efforts at invasion hubs can effectively contain the spread of invasions, few studies have demonstrated this in practice. In arid landscapes worldwid...
