Ion beam induced luminescence in natural diamond
نویسنده
چکیده
We used ion beam induced luminescence (IBIL) to study the evolution of damage during ion implantation of natural type-IIa diamond with 30 keV carbon ions, for different sample temperatures in the range 35-300 K. Blue band-Aluminescence decays with irradiation dose from an initial value of -10e3 photons/e-h pair. This decay was modeled to obtain an effective damage cross section of -40 A2, which is roughly independent of-temperature. We explored the use of IBIL as a tool to characterize the processing of p-n junctions in natural type-IIb diamond and apply it to find conditions that determine the ultraviolet response of light-emitting diodes.

Maskless milling of diamond by a focused oxygen ion beam
Recent advances in focused ion beam technology have enabled high-resolution, maskless nanofabrication using light ions. Studies with light ions to date have, however, focused on milling of materials where sub-surface ion beam damage does not inhibit device performance. Here we report on maskless milling of single crystal diamond using a focused beam of oxygen ions. Material quality is assessed ...
متن کاملEffect of dislocations on charge carrier mobility–lifetime product in synthetic single crystal diamond
The authors report correlations between variations in charge transport of electrons and holes in synthetic single crystal diamond and the presence of nitrogen impurities and dislocations. The spatial distribution of these defects was imaged using their characteristic luminescence emission and compared with maps of carrier drift length measured by ion beam induced charge imaging. The images indi...

The price of single point diamond tools with a sharp tip is very high due to complex machining process and highly expensive machining equipments. Yet, the performance is not quite satisfactory. In this paper, we have presented a very simple and cost effective machining process for the sharpening and polishing of diamond stylus using low energy reactive ion beam machining (RIBM). In our method, ...

متن کاملInvestigation of focused ion beam induced damage in single crystal diamond tools
In this work, transmission electron microscope (TEM) measurements and molecular dynamics (MD) simulations were carried out to characterise the focused ion beam (FIB) induced damage layer in a single crystal diamond tool under different FIB processing voltages. The results obtained from the experiments and the simulations are in good agreement. The results indicate that during FIB processing cut...
