Enterprise Architecture is increasingly seen as transcending enterprise-wide IT architecture. In its exalted conceptualization, EA provides the link between strategy and execution and is driven by strategic considerations such as business transformation and business agility. However, academic research on the topic is still relatively incipient. In particular, there is a gap in the literature as to what is EA's scope in terms of the organizational structure. In this paper, we define EA as strategic capability: it pertains to the strategic application of competencies to organize and utilize the organization-specific resources towards desired ends. Its "area of value ownership" is at the organizing level, linking between strategy and execution, and guiding the evolution of the operational core. Anything "lower" is mere design, while anything "higher" goes beyond a single organization's scope. This platform of competencies is essentially socio-technical and calls for enterprise engineering perspective with qualitatively different kind of disciplinary premises than information systems perspective, in which EA has its roots. Furthermore, we posit that EA as capability is required to properly govern business-driven, value-oriented enterprise transformation.

The applicability of a novel silicon precursor with respect to reasonable nanowire (NW) growth rates, feasibility of epitaxial NW growth and versatility with respect to diverse catalysts was investigated. Epitaxial growth of Si-NWs was achieved using octochlorotrisilane (OCTS) as Si precursor and Au as catalyst. In contrast to the synthesis approach with SiCl4 as precursor, OCTS provides Si without the addition of H2. By optimizing the growth conditions, effective NW synthesis is shown for alternative catalysts, in particular, Cu, Ag, Ni, and Pt with the latter two being compatible to complementary metal-oxide-semiconductor technology. As for these catalysts, the growth temperatures are lower than the lowest liquid eutectic; we suggest that the catalyst particle is in the solid state during NW growth and that a solid-phase diffusion process, either in the bulk, on the surface, or both, must be responsible for NW nucleation.
