Ion Sputtered Silicon Carbide
Classic ion-beam induced cone formation on sputtered Silicon Carbide. Impurities on the
original surface give rise to cone growth, shadowed from the incident ion bombardment. Ions
reflecting off the cones dig a deeper channel or moat around the base. Imaged with the MFP-3D AFM.
