In the Feature Article by Chris G. Van de Walle, J. L. Lyons, and Anderson Janotti on p. 1024 ff., mechanisms for electron accumulation on InN polar surfaces based on first‐principles calculations are discussed. The ball‐and‐stick model shown in the cover picture illustrates a (2 × 2) In‐adatom reconstruction on the InN c ‐plane (0001) surface. Indium atoms are purple, nitrogen blue. The orange isosurface illustrates the wave function of a surface state corresponding to In–In bonds. This state lies at an energy Δ above the conduction‐band minimum (CBM) and pins the Fermi level E F , as illustrated by the band‐bending diagram, resulting in an electron accumulation layer.
