Structural Characterisation of Heteroepitaxial Zincblende Gallium Nitride
… lighting, the mixing of light from red-, green- and blue- wavelength LEDs is desired. At present, the efficiency of green-wavelength LEDs based on InGaN is only about half that of red phosphide and blue nitride LEDs. This is known as the ‘green gap’ problem. III-nitrides based on the …

Less strain, more gain_nano_patterning III-N thin films
… regions of the light spectrum such as green and yellow, once found difficult to achieve in bulk planar LEDs, can be produced by manipulating the confinement and crystal facet growth directions of the active regions. A cheap and easily repeatable self-assembly nano-patterning technique …

Theoretical Investigations of the Photophysical Properties of Chromophoric Metal-Organic Frameworks
… An example is the presence of an indirect band gap. For organic semiconductors, such effects are typically precluded, since most organic materials employed are disordered, which hampers their characterization and theoretical analysis. The inspiration for this thesis came from the very first …
