Structural transformation and magnetic change of pure and 1% La/Nd‐doped multiferroic BiFeO3 (BFO) nanoparticles are presented to study the influence of introducing rare‐earth elements at the A‐site in BFO. All samples are successfully produced by the conventional hydrothermal method. Scanning electron microscopy picture demonstrates that doping has an impact on the surface and size of particles,...
Hexagonal monolayer AlN (h‐mAlN) is an indirect wide‐gap semiconductor and is attractive for use in optoelectronic devices. Herein, first‐principles calculations are performed to study the electronic, vibrational, elastic, and piezoelectric properties of H and F‐functionalized AlN sheets. The results indicate that the H‐/F‐functionalized (FAlNH) and fully H‐functionalized (HAlNH) sheets are thermodynamically...
