Figure 1 Schematic illustration of 3D-2D structural phase transition in a crystal

Caption

The direct 3D-2D structural phase transition was induced in (Pb1?xSnx)Se alloy epitaxial films by using a nonequilibrium growth technique. Reversible giant electronic property change was attained at x ~ 0.5 originating in the abrupt band structure switch from gapless Dirac-like state to semiconducting state.
