Polaron Density in Bulk Materials

Caption

Scientists have characterized for the first time in a large system of 9,000 atoms in 2D materials the fundamental properties of quasiparticles called polarons, a quantum wave packet consisting of an electron "dressed" by a cloud of atomic vibrations. This advance in polaron research can help improve development of touchscreens for phones and tablets, organic light-emitting diodes for TVs, hydrogen fuel generation from photocatalysis, and more.
