An intermediate morphology in the patterning of the crystalline Ge(001) surface induced by ion irradiation
Denise J. Erb, Daniel A. Pearson, Tomáš Škereň +3
We investigate the morphologies of the Ge(001) surface that are produced by bombardment with a normally incident, broad argon ion beam at sample temperatures above the recrystalliz…
Measurement of Ehrlich-Schwoebel barrier contribution to the self-organized formation of ordered surface patterns on Ge(001)
Peco Myint, Denise Erb, Xiaozhi Zhang +6
Normal incidence 1 keV Ar ion bombardment leads to amorphization and ultrasmoothing of Ge at room temperature, but at elevated temperatures the Ge surface remains crystalline a…
Site-controlled formation of single Si nanocrystals in a buried SiO2 matrix using ion beam mixing
Xiaomo Xu, Thomas Prüfer, Daniel Wolf +8
For future nanoelectronic devices - such as room-temperature single electron transistors - the site-controlled formation of single Si nanocrystals (NCs) is a crucial prerequisite.…
Implanting germanium into graphene
Mukesh Tripathi, Alexander Markevich, Roman Böttger +4
Incorporating heteroatoms into the graphene lattice may be used to tailor its electronic, mechanical and chemical properties. Direct substitutions have thus far been limited to inc…
Nano patterns self-aligned to Ga dimer rows on GaAs surfaces
Martin Engler, Tomáš Škereň, Stefan Facsko
Ion beam irradiation of semiconductors is a method to produce regular periodic nanoscale patterns self-organized on wafer scale. At low temperatures, the surface of semiconductors…
Charge Exchange and Energy Loss of Slow Highly Charged Ions in 1nm Thick Carbon Nanomembranes
Richard A. Wilhelm, Elisabeth Gruber, Robert Ritter +3
Experimental charge exchange and energy loss data for the transmission of slow highly charged Xe ions through ultra-thin polymeric carbon membranes are presented. Surprisingly, two…
Reverse epitaxy of Ge: ordered and facetted surface patterns
Xin Ou, Adrian Keller, Manfred Helm +2
Normal incidence ion irradiation at elevated temperatures, when amorphization is prevented, induces novel nanoscale patterns of crystalline structures on elemental semiconductors b…
Dynamic effects induced by renormalization in anisotropic pattern forming systems
Adrian Keller, Matteo Nicoli, Stefan Facsko +1
The dynamics of patterns in large two-dimensional domains remains a challenge in non-equilibrium phenomena. Often it is addressed through mild extensions of one-dimensional equatio…
Phase diagram for nanostructuring CaF surfaces by slow highly charged ions
A. S. El-Said, R. A. Wilhelm, R. Heller +6
Impacts of individual slow highly charged ions on alkaline earth halide and alkali halide surfaces create nano-scale surface modifications. For different materials and impact energ…
Nanopatterning of Si surfaces by normal incident ion erosion: influence of metal incorporation on surface morphology evolution
Jing Zhou, Stefan Facsko, Ming Lu +1
The morphology evolution of Si (100) surfaces under 1200 eV Ar+ ion bombardment at normal incidence with and without metal incorporation is presented. The formation of nanodot patt…
