The Classical-to-Quantum Crossover in strain-induced ferroelectric transition in SrTiO 3 membranes
The study investigates how mechanical strain can induce a reversible ferroelectric transition in single, ultrathin SrTiO3 membranes. Researchers found that while strain induces ferroelectricity, there is a crossover from classical to quantum behavior at low temperatures. This suggests that strain engineering can be used to control exotic quantum states in these materials.
