Abstract:
Microwave assisted synthesis of colloidal Nickel
nanocrystals is considered as an efficient technique to control
particle size and their uniformity. This method is suitable for
large-scale synthesis of the nanocrystals, which can have
significant applications in memory devices. In this paper, we
report microwave-assisted synthesis of colloidal nickel
nanocrystals with an average size distribution of 5 nm.
Colloidal nickel nanocrystals are spin coated over silicon
dioxide wafer to understand the spin coating process
reliability for memory device fabrication. Spin coated wafer
surface is studied using atomic force microscopy and energy
dispersive X-ray characterization methods. The synthesized
nanocrystals are used for fabrication of non-volatile memory
devices using spin coating process. We also present the
process flow for fabrication and capacitance-voltage (C-V)
characteristics of the fabricated device. Our results show
significant flat band voltage shift of 4 V that indicates an
excellent memory window for memory devic
