Abstract

Electronic devices have been going through intensive renovations in order to reply to the high demands of consumers. In the near future, electronic devices are projected to be incorporated into flexible and wearable modules to meet the everlasting needs. With the intention of turning this somewhat fantasy into reality, flexible and wearable electronic devices would require multiple core modules, such as display, logic, and memory to be integrated on a single substrate.

In this seminar, a graphene channel transistor based flexible and transparent memory (FTM) fabricated on Poly-ethylene-naphtalate (PEN) substrate will be presented as a memory module for flexible and transparent electronics. FTM samples were successfully fabricated through low temperature processes below 110℃ and characterized. The injection of electrons into the trap sites of a triple high-k dielectric stack resulted in excellent memory characteristics with large memory window. FTM might enable making a breakthrough in innovative design for electronics that has been impossible when using stiff and opaque substrates.

 

Biography

Sung Min Kim received B.S and M.S in Physics from KyungHee University Suwon, Korea in 1998 and 2000, respectively.
