Ni-Si Schottky barriers are fabricated by electrodeposition using n on n+ Si substrates. I -V , C-V and low temperature I -V measurements are presented. A high-quality Schottky barrier with extremely low reverse leakage current is revealed. The results are shown to fit an inhomogeneous barrier model for thermionic emission over a Schottky barrier proposed by Werner and Guttler [J.H. Werner, H.H. Guttler, Barrier inhomogeneities at Schottky contacts, J. Appl. Phys. 69 (3) (1991) 1522-1533]. A mean value of 0.76 V and a standard deviation of 66 mV is obtained for the Schottky barrier height at room temperature with a linear bias dependence. X-ray diffraction and scanning electron microscopy measurements reveal a polycrystalline Ni film with grains that span from the Ni-Si interface to the top of the Ni layer. The variation in Ni orientation is suggested as a possible source of the spatial distribution of the Schottky barrier height.

“…% of latex spheres, well-ordered templates have been self-assembled on glass substrates with buffer layers of sputtered Cr (10 nm) and Au (200 nm) or on HF-treated Si. These templates have been used as moulds to prepare nanoporous magnetic (Ni, Co, Fe, and Ni Fe ) structures by electrodeposition methods [5].…”

Shape-induced anisotropy in antidot arrays from self-assembled templates

et al. 2005

Using self-assembly of polystyrene spheres, well-ordered templates have been prepared on glass and silicon substrates. Strong guiding of self-assembly is obtained on photolithographically structured silicon substrates. Magnetic antidot arrays with three-dimensional architecture have been prepared by electrodeposition in the pores of these templates. The shape anisotropy demonstrates a crucial impact on magnetization reversal processes.

“…This technique offers new opportunities, which are not easily realized by standard lithographic methods, and allows us to create magnetic nano-structures with 3D architectures on a broad range of length scales, 20 -2000 nm. In this paper we briefly review our previous results [5][6][7][8][9][10][11][12][13] and in more detail describe some recent observations. We show that the 3D architecture of these structures produces many unique properties absent in nanostructures prepared by conventional lithographical techniques.…”
