My research area is carried out with the ultimate aim of developing devices with improved properties for various applications. My projects involve the preparation and characterization of the materials prior the device fabrication to investigate a change in structural, magnetic, optical and electrical properties. This research is highly significant to failure mechanisms in everyday electronic devices and appliances.
The research is carried out with the aim of developing devices with improved properties for various applications. The research is highly significant to failure mechanisms in everyday electronic devices and appliances. In achieving this aim, the set research objectives involve preparation and characterisation of the material prior to device fabrication. This is followed by the characterisation of material-based devices. Different material and device characterisation techniques are employed in this work to establish and investigate a change in crystal structural, magnetic, optical and electrical properties (behaviour) of the material at several operating conditions due to the surface and bulk manipulations.
The material of the main interest is Silicon. Silicon bulk is manipulated for the fabrication of efficient radiation sensors. Adopted research methodologies and data interpretations are extended to other materials for applications such as solar cells, advanced medical diagnostic and treatment, and data storage and processing. Other materials of specific interests are Semiconducting Polymer Nanocomposites, Multiwall Carbon Nanocomposites, Graphene-Oxide and compound semiconductors
