摘 要：The nanocrystalline ferroelectric LiNbO3films on(001)Si substrates with the random orientation of polycrystalline grains and the predominance of the grains with lateral orientation of the polar axis were grown using the ion beam sputtering method.The remanent polarization and the coercive field are 12μC/cm2 and 29 kV/cm,respectively.The thermal annealing leads to the coarsening of the grains.The appearance of the"local texture,"which gives rise to the unipolarity of the heterostructures caused by the predominance of the one direction in the vertical component of the spontaneous polarization,is investigated.
