Researchers report that the 2D form of tungsten ditelluride can undergo ‘ferroelectric switching.’ Materials with ferroelectric properties can have applications in memory storage, capacitors, RFID card technologies and even medical sensors – and tungsten ditelluride is the first exfoliated 2D material known to undergo ferroelectric switching.
2D materials can be prepared in crystalline sheets as thin as a single monolayer, only one or a few atoms thick...
