There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Eric Vogel“Low-Temperature Processed Materials for Neuromorphic Circuits”
Neuromorphic spiking networks and associated highly parallel architectures have been the object of much interest in recent years. These systems are expected to complement binary CMOS architectures in applications where substantial amounts of imprecise information have to be processed. Some of the applications where neuromorphic systems could outperform binary architectures include adaptive learning, pattern classification, and outcome prediction. Complex neuromorphic circuits using nanocrystalline-silicon (nc-Si) thin-film transistors (TFTs) and memristive (resistive switch) devices have been fabricated, modeled and simulated. Complex synaptic and learning behavior has been demonstrated as a natural outcome of using these specific devices. The low-temperature fabrication processes employed have several important potential consequences. First, the fabrication processes are consistent with the use of glass or flexible substrates. The neuromorphic architecture may provide for information processing that is more efficient than that expected for conventional TFT circuitry. Second, the fabrication processes are compatible with a CMOS process, which facilitates 3-D applications where the neuromorphic circuitry is integrated with a CMOS core. Finally, the results demonstrate the feasibility of fabricating a 3-D system with physical structure similar to the human neocortex.
About Professor Vogel
Eric M. Vogel is currently Professor of Materials Science and Engineering at the Georgia Institute of Technology (GIT).
