San Antonio Nano-Technology Forum (SANTF)

Advancing Emerging Nonvolatile Memory with Carbon Nanomaterials

Speaker: Prof. Chiyui (Ethan) Ahn, Assistant Professor of Electrical and Computer Engineering, The University of Texas at San Antonio (UTSA)

Venue: BSE Multipurpose Room (2.102), One UTSA Circle, San Antonio, TX 78249

Date: Wednesday, February 21, 2018
Time: 11.30 AM – 12.45 PM


With the advent of so-called ‘abundant data’ era and the required throughput and energy-efficiency for the next-generation computing paradigm, it becomes increasingly important to explore more scalable approaches for both computational (logic) and information storage (memory) devices. This is important, as the energy efficiency of computing circuits/systems has been increasingly limited by the memory and storage devices. In this seminar, a frontier research on the near- and long- term potential of emerging nanoscale non-volatile memories (NVMs) will be discussed to replace today’s ultimately scaled CMOS memories. The novel 1TnR (one-transistor-n-resistors) x-point memory array with carbon nanotube field-effect transistor as one-dimensional selection device and thus reduced sneak leakage is demonstrated as a cost-effective and 3D-stackable solution for the next-generation NVM architecture. It is also pointed out that the atomically thin graphene can be integrated with phase-change memory to improve the thermal efficiency of the NVM cell. Key challenges in integrating nanoscale materials to build up novel nano-devices (systems) will be addressed, and future perspectives on certain on-going research projects in the UTSA Nanoelectronics Laboratory (including spin-neuromorphic computing, epitaxial thin film oxides, energy harvesting) will be provided in the talk.

Biography of the Speaker:

Dr. Ahn is currently an Assistant Professor of Electrical Engineering and a founder and a principal investigator of the Nanoelectronics Laboratory at The University of Texas at San Antonio. Previously he served as a Sr. Process Engineer at Apple, Inc. (Cupertino, CA) and as a post-doctoral researcher at Stanford University. He received his Ph.D. in EE at Stanford University in 2015, under the supervision of Professor H.-S. Philip Wong. He joined Stanford in 2010, after a 3-year research career on the STT-MRAM technology with the KIST in Seoul, Korea. He received the B.S. and M.S. degrees in EE from the KAIST in Daejeon, Korea, in 2005 and 2007, respectively. He is the author of over 40 peer-reviewed research journal and conference papers and wrote one book chapter. His primary research interests include energy-efficient nanoscale logic and memory devices, low-dimensional nano-materials, electronic/thermal/magnetic transport in nanoscale devices, and novel devices in beyond-CMOS domain. Dr. Ahn has been the recipient of numerous awards and honors, including John Bardeen Research Award for Excellence in Nanodevice Research in 2014. He is currently serving as an ECE concentration chair for Electronic Materials and Devices at UTSA, and a technical committee member for IEEE Electron Devices Society (EDS) optoelectronic devices

SANTF Purpose:

SANTF aims to provide participants with information on the state of nanotechnology research in Greater San Antonio institutions, presents trends in industry and research universities, informs innovative applications of nanotechnology, information related to current work in progress towards establishing national skills standards, details the involvement and support of national professional societies, and the current technician education programs supported by the National Science Foundation (NSF). The newly formed SANTF strives to build stronger communication and networking opportunities between educational and private businesses, both regionally and nationally; to solidify pipelines in education and stimulate job creation in the Greater San Antonio area in the field of nanotechnology and STEM related fields.    


SANTF brings together researchers, innovators, entrepreneurs, and companies in the Greater San Antonio area working in the areas of nanomaterials and nanotechnology to showcase innovations related to the development and application of nanotechnology and nanomaterials. 


Establish a venue for local researchers, early-stage investors, venture capitalists, and industry leaders to gather and discuss developments in nanotechnology and its applications in the areas of Biomaterials, Energy, Clean Technology, and Sustainability.  

 SANTF brings together major technology players in the area to form strong alliances among the researchers at the University of Texas at San Antonio (UTSA), University of Texas Health Science Center at San Antonio (UTHSCSA), Southwest Research Institute (SwRI), Texas Biomedical Research Institute, Alamo Community Colleges, Trinity University, Texas State University in San Marcos, and other educational institutions. SANTF promotes intellectual creativity in the area of nanotechnology that will create a strong nanotechnology base in San Antonio.    

 The forum is expected to spur productive collaborations among the researchers in Greater San Antonio area and promote innovations leading to scientific discoveries and engineering innovations.  SANTF is committed to enhancing San Antonio’s nanotechnology future and establishing the Alamo City as a global leader in nanotechnology.
