III-V compound semiconductors are a different class of semiconductors that have unique properties not found in the more well known silicon. One of these unique features is that most III-V semiconductors have direct bandgap. In addition by using ternary or quaternary alloys of these semiconductors, the bandgaps can be continuously varied over a wide range. These properties have made III-V semiconductors the most dominant materials for optoelectronic device applications, where these devices are found in daily life such as the internet, lighting applications, disc-players etc.
The research carried out in the department deals from the growth of these materials to the structural, electrical and optical characterisation in order to understand the growth mechanism and material properties.
