Vanadium oxide (VO2), a material that has the ability to remember the entire history of the stimuli it receives. POWERlab / 2022 EPFL - EPFL scientists have found that vanadium oxide (VO2), a material used in electronics, has the ability to remember the entire history of the stimuli it receives. This is the first material to be identified as such, but there may be others. This discovery was a fluke. Mohammad Samizadeh Nikoo, a PhD student in the Power Semiconductor Devices Laboratory (POWERlab) , wanted to study the transition of vanadium oxide (VO2). Without load and at room temperature, it exhibits an insulating phase. When it is energized and heated to 68 degrees Celsius, it transforms into a metal.
