Originally the term ‘morphotropic’ referred to phase transitions due to changes in composition 1,2, but it has come to be used mainly for the common ‘morphotropic phase boundaries’ (MPB) that separate ...
Vibrational spectroscopy of lead-free potassium sodium niobate and related perovskite ferroelectrics
The potassium sodium niobate (K x Na 1 −x)NbO 3 (KNN) family with the perovskite structure is a technologically important lead-free piezoelectric material. At first, the nature of end members, the ...
