GaN and InN nanowires grown by MBE: a comparison
Morphological, optical and transport properties of GaN and InN nanowires
grown by molecular beam epitaxy (MBE) have been studied. The differences
between the two materials in respect to growth parameters and optimization
procedure was stressed. The nanowires crystalline quality has been investigated
by means of their optical properties. A comparison of the transport
characteristics was given. For each material a band schema was shown, which
takes into account transport and optical features and is based on Fermi level
pinning at the surface.Comment: 5 pages, 5 figure
Diversity in collaborative research communities: a multicultural, multidisciplinary thesis writing group in public health
Writing groups for doctoral students are generally agreed to provide valuable learning spaces for Ph.D. candidates. Here an academic developer and the eight members of a writing group formed in a Discipline of Public Health provide an account of their experiences of collaborating in a multicultural, multidisciplinary thesis writing group. We consider the benefits of belonging to such a group for Ph.D. students who are operating in a research climate in which disciplinary boundaries are blurring and where an increasing number of doctoral projects are interdisciplinary in nature; in which both academic staff and students come from enormously diverse cultural and language backgrounds; and in which teamwork, networking and collaboration are prized but not always proactively facilitated. We argue that doctoral writing groups comprising students from diverse cultural and disciplinary backgrounds can be of significant value for postgraduates who wish to collaborate on their own academic development to improve their research writing and communication skills; at the same time, such collaborative work effectively builds an inclusive, dynamic research community.Cally Guerin, Vicki Xafis, Diana V.
