High current density and low turn-on field from aligned Cd(OH)2 nanosheets.

High current density of 9.8 mA/cm 2 was drawn at an applied field of 4.1 V/μm from aligned Cd(OH) 2 nanosheets and low turn-on field of 1.4 V/μm was found for the emission current density of 10 μA/cm 2 . The aligned Cd(OH) 2 nanosheets were synthesized by CBD technique on Cadmium foil. To the best of our knowledge this is the first report on the field emission studies of Cd(OH) 2 nanosheets. Simple synthesis route coupled with superior field emission properties indicate the possible use of Cd(OH) 2 nanosheets for micro/nanoelectronic devices. [ABSTRACT FROM AUTHOR]
