We study the role of the effective mass, band mixing, and phonon emission on multiexciton generation in IV-VI nanocrystals. A four-band k · p effective mass model, which allows for an independent variation of these parameters, is adopted to describe the electronic structure of the nanocrystals. Multiexciton generation efficiencies are calculated using a Green's function formalism, providing results that are numerically similar to impact excitation. We find that multiexciton generation efficiencies are maximized when the effective mass of the electron and hole are small and similar. Contact with recent experimental results for multiexciton generation in PbS and PbSe is made.
Purpose
The purpose of this paper is to explore the emplotment of organizational grand-narratives of a leading international organization, the Organisation for Economic Co-operation and Development (OECD). The paper includes the reconstruction of the OECD’s inclusion approach as a prototype grand-narrative. Moreover, the main goal of this paper is understanding the reciprocal relationship between the organizational narratives and other organizational domains.
Design/methodology/approach
To study the structural process of emploting grand-narratives, which combines reciprocal dependencies across organizational domains, I have used process tracing, content analysis and interviews methodologies, for each domain. These methodologies were monitored by quantitative and qualitative analyses of the interactions among these domains. These methods allowed me to explore the interdependencies in the discursive and non-discursive ordering of institutional memory as a means for identifying the development of organizational narratives.
Findings
The findings of this paper confirm the reciprocal dynamics among and within three core organizational domains, narratives, organizational-epistemological settings and organizational products. These domains evolve constantly and concurrently in a three-phased process where a former organizational constellation is challenged, a consolidation takes place, and a new narrative is institutionalized. The context I chose to demonstrate this dynamic is the OECD evolving interactions between innerorganizational units and the organizational products (i.e. its activation policy recommendations), of the OECD post-Cold War inclusive approach (1989–2002).
Research limitations/implications
The importance and complexity of the OECD as a global trendsetting organization, and the findings of this single case study are significant for their implications on trends and processes found in other complex grand-narratives. The transferability of these results would require further analysis.
Originality/value
The originality of this paper is using a transnational dynamic organization such as the OECD as the organizational model for understanding how organizations undergo emplotment processes. Moreover, this article’s analytical framework provides a deeper understanding of the complex interplay between the constraining structures and micro-level interactions.
