Quantization of surface Dirac states could lead to exotic applications

Scientists have uncovered the first evidence of an unusual quantum phenomenon - the integer quantum Hall effect - in a new type of film, called a 3D topological insulator. In doing this, they demonstrated that 'surface Dirac states' - a particular form of massless electrons - are quantized in these materials, meaning that they only take on certain discrete values.
