A deterministic single-ion source for microscopy and implantation — Felix Stopp, Luis Ortiz-Gutierrez, •Henri Lehec, and Ferdinand Schmidt-Kaler — QUANTUM, Institut für Physik, Universität Mainz, Staudingerweg 7, 55128 Mainz, Germany
We developed a deterministic single ion source based on cold ions extracted from a Paul trap and demonstrated a beam focus of 5.8(1.0) nm [1]. Using this first generation ion source, implantation of single N2+ in diamond and Pr+ in YAG [2] was performed, with an accuracy of about 20 nm. In this poster, the development of a second generation single ion source will be presented. This apparatus is more compact, highly stable, and modular. We aim for a focus spot of 1 nm and we envision a single ion extraction rate of 1 kHz for fast data acquisition. Our source will be used to implant arrays of single phosphorus ion in silicon surfaces in collaboration with the Australian cluster of excellence [3,4].
