GaAs next nearest neighbour

AbstractWhen physicists form atomic surfaces using the technologically important semiconductor material gallium arsenide (GaAs), the surfaces appear in one of two kinds of state: flat or rough. But a team of physicists from Universisty of Arkansas, Albany and Oklahoma show experimentally that there’s a third type of surface, and this state depends upon the interactions of distant atomic neighbours.This is a short news story only.
