“…Recent examples of such strain-functionality coupling include the control of metal-to-insulator transition temperature in VO2 5 and the insulator-tosuperconductor transition temperature in La1.9Sr0.1CuO4 6 . Going beyond the ability to effectively manipulate already existing physical properties of a given material, strain has also been shown to invoke entirely new exotic ground states such as ferroelectricity in SrTiO3 and increased ferroelectric polarization in BaTiO3, consistent with theoretical predictions [7][8][9] .…”

“…Thus, for experimental measurements of these systems to provide meaningful insight, the external parameters, the intrinsic interacting degrees of freedom, and the resulting properties must all be well characterized. Hence, measurements on samples subject to external perturbations, for example pressure and strain [5][6][7][8][9][10] , can provide additional insight into the underlying physics of these systems.…”

“…7,8,12,[16][17][18] strongly correlated electron system that exhibits a characteristic metal-insulator transition (MIT) at ∼68 • C, where its resistance decreases by more than four orders of magnitude. 19 Tokura et al used ionic liquids to reversibly switch epitaxial VO 2 films between insulating and metallic states.…”

“…7,8 However, S. P. Parkin et al proposed an entirely different mechanism to explain the ionic-liquid-controlled MIT in VO 2 films. 12,16 They believed that the electric-field-induced migration of oxygen vacancies in the VO 2 film by ionic liquids was critical for understanding the mechanism of the electrically manipulated MIT. Thus, it remains unclear how ionic liquids influence the transport properties of VO 2 films, and the tuning mechanism is not yet fully understood.…”
