- 1. J. Appl. Phys. 100, 074313 (2006) , “Deep levels in silicon Schottky junctions with embedded arrays of ß -FeSi2 nanocrystallites”, A. Tsormpatzoglou, D. H. Tassis, C. A. Dimitriadis, L. Dózsa, N. G. Galkin, D. L. Goroshko, V. O. Polyarnyi, and E. A. ChusovitinSchottky contacts on p-type silicon, with embedded arrays of β-FeSi2 nanocrystallites, were studied by current-voltage (I-V), deep level transient spectroscopy (DLTS), and low-frequency noise measurements. Forward I-V characteristics on logarithmic... (Read more)

Dobaczewski, N. V. Abrosimov, Z. R. ytkiewicz, and A. R. PeakerLaplace transform deep level transient spectroscopy (LDLTS) is used to investigate the alloy effects on iron related deep centers in Si1−xGex. A clear buildup of alloy disorder as a function of the germanium content has been observed for the isolated... (Read more)

PeartonThe properties of semi-insulating GaN films with the lower part of the film doped with Fe are reported. The 300 K sheet resistivity of the films was 2×1010 /square with an activation energy of the dark conductivity of 0.5 eV. The Fermi level is also pinned at... (Read more)
- 4. Appl. Phys. A 30, 1 (1983) , “Transition Metals in Silicon”, E. R. Weber.A review is given on the diffusion, solubility and electrical activity of 3d transition metals in silicon. Transition elements (especially, Cr, Mn, Fe, Co, Ni, and Cu) diffuse interstitially and stay in the interstitial site in thermal equilibrium at the diffusion temperature. The parameters of the liquidus curves are identical for the Si:Ti — Si:Ni melts, indicating comparable silicon-metal interaction for all these elements. Only Cr, Mn, and Fe could be identified in undisturbed interstitial sites after quenching, the others precipitated or formed complexes. The 3d elements can be divided into two groups according to the respective enthalpy of formation of the solid solution. The distinction can arise from different charge states of these impurities at the diffusion temperature. For the interstitial 3d atoms remaining after quenching, reliable energy levels are established from the literature and compared with recent calculations. (Read more)
