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, ...

A superconducting wire can be considered as quasi-one dimensional (1D) if its characteristic transverse dimension is smaller than the coherence length ξ. The shape of the bottom part of the resistive transition R(T) of a not too narrow 1D strip is well described by the model of thermally activated phase slips [1,2]. However, if the wire width falls into a ~ 10 nm range, there are predictions th...
