Web9 jun. 2008 · A single crystalline diamond tool, with 25 µm length in the cutting edge and smooth face quality, has been successfully fabricated by using a FIB. These excellent tool characteristics are proven in the results obtained from the machining experiments done on the ultra-precision machine. WebThe simplest and most widely used ion beam column design consists in two lenses (namely a condenser and objective lens) to focus the ion beam on the sample, a beam-defining apertures to select the beam diameter and probe current, deflection plates to raster scan the beam over the sample surface, an octupole stigmator to ensure a circular beam shape, …
WebThe ion beam was directed parallel to the c axis; each ion impact created an amorphous columnar track of radius 3.5 nm. The second, untwinned crystal, was not irradiated, but kept as the pristine reference sample.
