Over 0.1 W root-mean-square output achieved in magneto-mechano-electric generators using Mn-doped PIN-PMN-PT single crystals

Here, the authors report magneto-mechano-electric energy generation based on Mn-doped PIN–PMN–PT single crystals. Their device provides sufficiently high and stable output power density for efficient self-powered operation of wireless IoT systems and other large-scale energy harvesting applications.

Nanoengineering room temperature ferroelectricity into orthorhombic SmMnO₃ films

Multiferroic materials exhibiting ferromagnetism (FM) and ferroeletricity (FE) at room temperature (RT) are promising for applications. Here, the authors demonstrate by inducing strain in SmMnO3 via introducing vertically aligned nanocomposites that exchange coupling can be modified tuning the system from anti-FM to FM and simultaneously inducing FE at RT.

SrNbO₃ as a transparent conductor in the visible and ultraviolet spectra

Optically transparent electrodes with high electrical conductance are essential for the implementation of optoelectronics, but current technology performs poorly in the ultraviolet regime. Here, SrNbO₃ is proposed as an alternative material due to its high figure of merit in the ultraviolet range.
