Gayan WADUMESTHREE

This study is focused on growing and developing several magnetic nano materials for possible gas sensing applications. To fill the gap of finding low cost solutions for accurate measurements of magnetic characteristics of the newly developed materials, the following goals will be pursued:
01. Synthesis of Co, Fe, Ni based ZnO magnetics nanomaterials.
02. Carry out morphological, structural and magnetics characterization of the grown materials.
03. Fabricate nano magnetic gas sensors and study their characteristics and performance.
04. Optimize device performance by optimizing the material properties by changing the synthesis parameters.
