Printed Flash Memories and Sensors (Printed Electronics Europe 2014)

Dr Roy Vellaisamy, Assistant Professor
City University of Hong Kong
Hong Kong
Apr 02, 2014.

Presentation Summary

  • Floating gate flash memory devices have gained a great deal of attention due to the simple device structure, non-destructive read-out and controlled trap capacity.
  • On the other hand, attractive mechanical properties and the possible biocompatibility of thin film transistors structure will be explored for direct integration of sensing devices with biological systems, as gas sensors in the food industry and environmental monitoring applications.
  • solution processable or printable materials for flash memories and sensors will be discussed.

Speaker Biography (Roy Vellaisamy)

Roy completed his PhD in 2004 on light emitting materials, mainly on ESR (Electron Spin Resonance) analysis of organic materials. For his post-doctoral studies, he focused on the growth of various organic molecules for light emitting transistors (LET) and opto-electronic characterization of LETs. In 2004, he joined the Department of Chemistry at The University of Hong Kong and he focused on various molecular materials for electronic device applications. Currently, as an associate professor, he is leading a group of Physicists, Chemists and Engineers for the fabrication of functional self-assembly materials for various electronic devices and integration of such devices for printed electronics and energy harvesting devices.
