How the experiment take place?
In his experiments, Samizadeh Nikoo applied an electric current to a sample of VO2. “The current moved across the material, following a path until it exited on the other side,” he explains. As the current heated up the sample, it caused the VO2 to change state. And once the current had passed, the material returned to its initial state.
