Scanning tunneling microscopy images are reported for the wurtzite GaN(0001) surface. Terraces are observed, with three kinds of defect structures that are assigned to ordered N-vacancies: (i) striations perpendicular to the step edges, (ii) row defe

The wurtzite GaN(0001) surface is imaged by scanning tunneling microscopy. Terraces are observed with line-defect structures on them: primarily regularly spaced striations perpendicular to step edges. A model of these striations as ordered N-vacancie

SUMMARY Using a scanning tunnelling microscope tip formed by cutting a platinum wire, we have modified the surfaces of gold and Hg1-xCdxTe on a nanometre scale by mechanical contact between the tip and the surface. By using the same tip to form image

Studies of electrochemically etched tungsten scanning tunneling microscope tips, using scanning electron microscopy, show that (i) the tips are often convolved or bent if the mass of the tungsten wire submerged in the etchant is large (an effect ascr
