Surface-Effect-Induced Optical Bandgap Shrinkage in GaN Nanotubes
Park, Young S.,Lee, Geunsik,Holmes, Mark J.,Chan, Christopher C. S.,Reid, Benjamin P. L.,Alexander-Webber, Jack A.,Nicholas, Robin J.,Taylor, Robert A.,Kim, Kwang S.,Han, Sang W.,Yang, Woochul,Jo, Y. American Chemical Society 2015 NANO LETTERS Vol.15 No.7
<P>We investigate nontrivial surface effects on the optical properties of self-assembled crystalline GaN nanotubes grown on Si substrates. The excitonic emission is observed to redshift by ∼100 meV with respect to that of bulk GaN. We find that the conduction band edge is mainly dominated by surface atoms, and that a larger number of surface atoms for the tube is likely to increase the bandwidth, thus reducing the optical bandgap. The experimental findings can have important impacts in the understanding of the role of surfaces in nanostructured semiconductors with an enhanced surface/volume ratio.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2015/nalefd.2015.15.issue-7/acs.nanolett.5b00924/production/images/medium/nl-2015-00924p_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl5b00924'>ACS Electronic Supporting Info</A></P>

Quality performance information has been regarded as a significant step toward managing public performance. Although a correlation between the quality of information and its actual usage among managers in high-accountability policy areas has been found, quality performance information has not been properly provided to practitioners. This study takes an Institutional Analysis and Development approach to assess an appropriate institutional framework that facilitates state agencies and academics to coproduce this information. Based on a conceptual framework, we analyze a public information system of the Workforce Data Quality Initiative in Ohio and carry out a content analysis with NVIVO. It is found that arrangements that can manage the incentive dynamic in this process may help to align heterogeneous stakeholders in a mutually supportive fashion. Also, the research agenda and information resulted from being coproduced for management and academic purposes, simultaneously. This use of administrative data sheds light on how quality performance information can be coproduced under an appropriate institutional arrangement between administration and research communities. It is suggested that accessibility to the information system among various stakeholders should be improved.
