Novel Study of Strain-Induced Piezoelectricity in VO₂.

ABSTRACT: VO₂ is well known for its dual-phase transitions, electrical and structural, at a single temperature of 340 K. The low-temperature structural phases of VO₂ are different from their high-temperature counterpart in terms of structural symmetry. The strain-induced modification of the structural distortion in VO₂ is studied in detail. A ferroelectric-type distortion is observed, and therefore, the piezoelectric effect in the low-temperature phases of VO₂ is investigated, for the first time, by piezoresponse force microscopy. Strain is one of the factors that can modify the electronic behavior of piezoelectric materials. At the same time, the two low-temperature phases of VO₂ (M1 and M2) can only be separated by the application of strain. T
