Research Interests

Investigation of chemical interactions on semiconductor surfaces, including Schottky Barrier formation, surface exchange reactions, surface chemical passivation and heteroepitaxial growth. Investigations of the interactions of group VI elements with semiconductor surfaces with the specific objective of improving the electrical characteristics of multiplayer structures fabricated on these surfaces. Electrical and chemical characterisation of thin film dielectric layers used in advanced transistor fabrication technology. Developing an understanding of the chemical and structural interactions of organic molecules with semiconductor surfaces. These studies involve investigation of direct bonding mechanisms between organic molecules and surface atoms with a view to exploiting these hybrid organic-inorganic structures for novel electronic device and sensor applications.
