Michigan Ion Beam Laboratory FOR SURFACE MODIFICATION AND ANALYSIS
This report summarizes the principal research activities in the Michigan Ion Beam Laboratory during the past calendar year. Fifty-six researchers conducted thirty-one projects at MIBL that accounted for over 3200 hours of equipment usage. The programs included participation from researchers at the University, corporate research laboratories, private companies, government laboratories, and other...
متن کاملNanoscopic surface modification by slow ion bombardment
We present systematic scanning tunneling microscopy (STM)/atomic-force microscopic (AFM) investigations on nanoscopic defect production at atomically clean surfaces of SiO2, Al2O3 and highly oriented pyrolytic graphite (HOPG) after bombardment by slow (impact energy ≤ 1.2 keV) singly and multiply charged ions under strict ultra-high vacuum (UHV) conditions. Combined STM and AFM studies show tha...
متن کاملIon-beam Mixing and Solid-state Reaction
Vapor-deposited Zr-Fe multilayered thin films with various wavelengths and of overall composition either 50% Fe or Fe-rich up to 57 % Fe were either irradiated with 300 keV Kr ions at temperatures from 25K to 623 K to fluences up to 2 x 10l6 cm-2, or simply annealed at 773K in-situ in the Intermediate Voltage Electron Microscope at Argonne National Laboratory. Under irradiation, the final react...
متن کاملShape-modification of patterned nanoparticles by an ion beam treatment
This paper evaluated a practical approach to the fabrication of arrays of non-spherical nanoparticles by colloidal etching without a mask involving exposure to a low energy ion beam. A spherical nanoparticle array was transferred using a soft nanolithography technique, which is a simple and effective pattern transfer method for nanostructures on the surface of thin adhesive polymers on a planar...
متن کاملImproved atomic force microscope cantilever performance by ion beam modification
The performance of atomic force microscopy cantilevers, as measured by the resonant frequency and spring constant, is directly dependent on the shape of the cantilever. Here we have improved the performance of conventional silicon nitride cantilevers by using focused ion beam milling to minimize the width of the cantilever legs. The resonant frequency in solution for any given spring constant i...
