Electrochemical synthesis of CuSCN nanostructures, tuning the morphological and structural characteristics: From nanorods to nanostructured layers

Autor: Daniel Ariosa, Katherine Álvarez, Enrique A. Dalchiele, G. Riveros, Ricardo E. Marotti, Daniel Ramírez, Francisco Martín, José R. Ramos-Barrado, Bárbara González, C. J. Pereyra

Publikováno v: Materials Science in Semiconductor Processing. 68:226-237

P-type CuSCN nanorods (NRs) grown on CuSCN seed layers were obtained with modulated diameters through an electrochemical procedure. Their morphological, structural, optical, electrochemical and photoelectrochemical features were studied in depth. Mor
