Synthesis and characterization of CuGaSe2 nanoparticles prepared by a microwave method
Copper gallium diselenide (CuGaSe 2 ) nanopowder is a p-type semiconductor potentially for use as a thermoelectric material. Nanoparticles of CuGaSe 2 were synthesized by a microwave method using Cu(NO 3 ) 2 • 3H 2 O, Ga 2 (SO 4 ) 3 and SeO 2 as precursors and ethylene glycol as a solvent. A pr...
