We investigated the adsorption structures of K atoms on a GaAs(110) surface as a function of coverage by scanning tunneling microscopy. We found three kinds of adsorption structures, namely, the low-density linear chain, the asymmetric chain and the symmetric chain. At the initial stage with low coverage, K atoms form low-density linear and asymmetric chains. With increasing coverage, low-density linear chains disappeared and the number of asymmetric chains increased. At high adsorption coverage, K atoms began to form symmetric chains, so that the symmetric and asymmetric chains coexisted. The strong dependency of the adsorption structure on the coverage is discussed by considering a recent theoretical work.
