This unique class of materials is commanding much attention now because they can display properties such as colossal magnetoresistance and high-temperature superconductivity, which are highly coveted by the high-tech industry
Wu says that in the future strain engineering might be achieved by interfacing a correlated electron material such as vanadium oxide with a piezoelectric – a non-conducting material that creates a stress or strain in response to an electric field.
“By applying an electric field, the piezoelectric material would strain the correlated electron material to achieve a phase transition that would give us the desired functionality,” says Wu. ”To reach this capability, however, we will first need to design and synthesize such integrated structures with good material quality.”
