TL;DR: In this article, conversion electron Mossbauer Spectroscopy (CEMS) was employed in order to study the mixing induced by swift Au and Ag ions at the Fe/Si interface in a Fe/Fe57/Si system, and an increase in the amount of mixing with ion fluence and electronic energy loss was observed.
Abstract: Conversion Electron Mossbauer Spectroscopy (CEMS) was employed in order to study the mixing induced by swift Au and Ag ions at the Fe/Si interface in the Fe/Fe57/Si system. An increase in the amount of mixing with ion fluence and electronic energy loss (Se) has been observed. Atomic Force Microscopy (AFM) results provided indirect evidence to support the above observations.

TL;DR: In this paper, a wide-angle novel X-junction switch (TSXB) was proposed to achieve a bandwidth of 145 nm at 1.5 dB over which the crosstalk is kept below −18.0 dB.
Abstract: We report here in detail the WDM performance of a wide-angle novel X-junction switch (TSXB) that we developed earlier. At a full branching angle of 1.5°, our new design achieves a bandwidth of 145 nm (1470–1615 nm) at 1.5 dB over which the crosstalk is kept below −18.0 dB. Maintaining the same order of bandwidth in normal X-junctions (NXB) requires a branching angle as narrow as 0.2°. A TSXB is thus suitable for WDM systems, yet comes in a size significantly more wide angle (and hence more compact) than an NXB. © 2001 John Wiley & Sons, Inc.

TL;DR: In this paper, the design and simulation performance of a digital push-pull switch based on a wide-angle, asymmetric X-junction was reported, and at a full-branching angle of 1.2°, the crosstalk and (straight-port) transmission at the zerovoltage state were −19 and −0.92 dB, respectively.
Abstract: We report the design and simulation performance of a digital push–pull switch based on a wide-angle, asymmetric X-junction that we recently proposed (truncated-structural X-branch). At a full-branching angle of 1.2°, the crosstalk and (straight-port) transmission at the zero-voltage state were −19 and −0.92 dB, respectively. In the switched state, they are −17.45 and −1.06 dB, respectively. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 208–211, 2001.
