In meeting the requirements of a dissertation, the author is typically asked to publish three
first-author publications. This dissertation comprises a collection of publications as well as …

The accurate prediction of bandgap energy Eg is crucial for the future development of
semiconductors. Ab initio simulation studies have been undertaken to unravel the intricacies …

In this paper we show a proof of concept for the application of the supercontinuum light
source as a probing beam in photoreflectance (PR) and photoacoustic (PA) spectroscopies …

Nitride semiconductors are promising for applications in opto-electronic devices due to their
wide band gap that is adjustable by appropriate choice of alloy composition. To date, many …
