Abstract
The atomic geometry of the (Formula presented) Bi reconstruction on the InAs(110) surface has been fully determined by means of grazing incidence x-ray diffraction. The (Formula presented) Bi phase is characterized by couples of unequivalent Bi chains bonded alternatively to In and As atoms. The chains are strongly buckled with respect to the (110) InAs plane and they can easily accommodate if the InAs(110) substrate presents alternate missing rows in the [1-10] direction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
