Silver nanoparticles demonstrate better memory properties in plastic electronics

01 Aug 2011

Scientists at Hong Kong Polytechnic University have demonstrated silver nanoparticle-based transistors that have larger memory at high temperatures.

The team undertook a study on temperature-dependent behaviour of plastic electronics. They heated a non-volatile memory transistor made of plastic pentacene and combined with silver nanoparticles. At 90º the nanoparticles formed together in groups, leading to a decrease in the device's memory window. At higher temperatures the memory window increased, according to a report on AZO Nano.

The findings could be used to endow plastic electronic chips with better memory properties. The scientists report that the relationship between memory window and heat could be applied in applications that require measurement and storage of temperature profiles, and heat sensing.
