II-nitride based semiconductor materials have attracted interest since they

have excellent physical, electrical, and optical properties, and their high

chemical and thermal stability as compared to traditional III-V semiconductors.

The UV capabilities of III-nitride based semiconductor materials have special

attraction for civilian applications such as air and water sterilization, efficient

white lighting, high density optical data storage and military applications such

as biological agent detection and non-line-of-sight communication etc. In last

10 years AlN and AlGaN have received a great deal of attention for use as a

template layer for deep UV (DUV) emitter and detector applications because

of their promising features such as UV transparency, good thermal stability

and high thermal conductivity. Generally, the surface morphology and defect

density of AlGaN and the upper quantum-well active layer of DUV devices

depend significantly on the crystalline quality of the underlying AlN template;

therefore, obtaining AlN with a smooth surface and low threading dislocation

(TD) density is critical to improve DUV device performance. In this study we

have investigated the effects of pulsed MOVPE growth of AlGaN epilayers on

structural, morphological and optical properties.
