Possible ferroelectricity in perovskite oxynitride SrTaO(2)N epitaxial thin films
Compressively strained SrTaO(2)N thin films were epitaxially grown on SrTiO(3) substrates using nitrogen plasma-assisted pulsed laser deposition. Piezoresponse force microscopy measurements revealed small domains (10(1)–10(2) nm) that exhibited classical ferroelectricity, a behaviour not previously...
