Stencil lithography is used here for the fabrication of bismuth nanowires using thermal evaporation. This technique provides good electrical contact resistance by having the nanowire structure and the contact pads deposited at the same time. It has also the advantage of modulating nanowires’ height as a function of th…

When one attempts to modulate and control the characteristics of composite materials, limit of the modulation may be dictated by the mathematical threshold of the percolation transition. We report our computer simulation, in which percolation behavior can strongly be controlled by introducing size differences in the i…

Abstract In this work, the effect of Al ternary alloy addition on Ni–Ti alloys has been investigated. It has been seen that, with Al addition, martensite transformation temperatures decrease at different rates in Ti-rich and Ni-rich alloys. The paraequilibrium temperature, T 0 , and the chemical driving force for mart…
