SYNTHESIS OF ULTRA-LONG HOLLOW MERCURY TELLURIDE (HgTe) CHALCOGENIDE NANOFIBERS FROM Co AND Ni SACRIFICIAL NANOFIBERS

This paper describes a procedure based on electrospinning for generating sacrificial Co and Ni nanofibers with control dimensions and morphology. We have combined electrospinning and galvanic displacement reaction to fabricate ultralong hollow chalcogen and chalcogenide nanofibers in a cost- effective and high through put manner. This technique is a general route of forming various ultra-long hollow semiconducting nanofibers. The aim of this study is to exploit the structural and compositional changes during the formation of HgTe chalcogenide with a view of fabricating a mercury senor.
